Basics

3 Basics

3.1 Measurement of Infrared Temperatures

Every object emits an amount of infrared radiation (IR) according to its surface temperature. The intensity of the infrared radiation changes with the temperature of the object. Depending on the material and surface properties, the emitted radiation lies in a wavelength spectrum of approximately 1 to 20 µm. The intensity of the infrared radiation (”heat radiation”) is dependent on the material. For many substances this material-dependent constant is known. It is referred to as ”emissivity value”, see appendix 10.2 Typical Emissivity Values on page 57. Infrared thermometers are optical-electronic sensors. These sensors are able to detect ”radiation of heat”. Infrared thermometers are consist of a lens, a spectral filter, a sensor, and an electronic signal processing unit. The task of the spectral filter is to select the wavelength spectrum of interest. The sensor converts the infrared radiation into an electrical signal. The connected electronics process this signal for further analysis. The intensity of the emitted infrared radiation is thereby used to determine the temperature of the target. Since the intensity of the infrared radiation is dependent on the material, the appropriate emissivity can be selected on the sensor. The biggest advantage of the infrared thermometer is its ability to measure temperature without the need to be in contact with the target. Consequently, surface temperatures of moving or hard to reach objects can be easily measured.

3.2 Emissivity of Target Object

For accurate temperature readings, the sensor must be set to the appropriate emissivity value for the target material. Determine the emissivity of the target object as described in appendix 10.1

Determination of Emissivity on page 57.

When measuring materials with low emissivity, the results could be effected by interfering infrared radiation from background objects (such as heating systems, flames, fireclay bricks, etc. near to or behind the target object). This type of problem can occur when measuring reflective surfaces and very thin materials such as plastic films and glass. This error can be reduced to a minimum if particular care is taken during installation, and the linescanner is shielded from reflected infrared radiation.

Installation

The temperature inside the housing must be between 0°C to 60°C (32°F to 140°F) during

5 Installation

Linescanners are able to measure temperature values along a line through the use of a rotating mirror. For 25% of its revolution, the linescanner scans the field of view (FOV). This corresponds to a scan angle of 90°. The remaining 75% of its revolution is used for the internal operation of the sensor. The rotating mirror views the scene and reflects the infrared energy striking it onto a system of lenses which focuses the radiation onto a thermoelectrically cooled detector. The incoming signal is scanned, digitized, and then converted to temperature values by the internal microprocessor. For every revolution of the mirror, up to 1024 measured values will be internally collected. An air purge system keeps the scanner’s window free of dust, debris, and condensation.

5.1 Ambient Temperatures

Without water cooling, the linescanner is designed for ambient operating temperatures between 0°C and 50°C (32°F and 122°F). With water cooling, it can be used in environments of up to 180°C (356°F), see section 5.9 Water Cooling, page 26. The internal temperature is the determining factor for proper operation of the linescanner. It is displayed in the DataTemp software. The difference between the external ambient temperature and the temperature inside the housing also depends on the thermal contact of the linescanner and its mounting hardware.

operation and never more then 65°C (150°F) at any time, including non-operation!

5.2 Environment

The linescanner complies with class IP65 and is therefore dust and splash resistant. The linescanner’s window is made of a material that is resistant to thermal stresses and it is equipped with an integrated air purge system which protects the window against contamination. Air supply for the air purge should be oil free, clean “instrument“ air.

5.3 Electrical Interference

To minimize electrical or electromagnetic interference, follow these precautions:

• Mount the sensor as far away as possible from possible sources of interference such as motorized equipment producing large step load changes!

• Ensure a fully insulated installation of the sensor (avoid ground loops!).

• Make sure the shield wire in the sensor cable is earth grounded at one location!

• To avoid potential differences use a single power circuit to power both the linescanner and the

PC running the software!

5.4 Geometry

The smallest possible object which can be measured depends on two conditions:

1. The area measured must be no less than 90% (90% energy response).

2. Hot spots must be clearly detected, when in front of a cold background (50% energy response).

Remark: The measured area for 50% energy response is approximately ⅓ of the area size of the measured spot for 90% energy response.

surface of housing)

Figure 7: Relationship between scan line width and distance to target

The relationship between the scan line width (L) and the distance (D) to the front side of the linescanner housing is defined as described above. For long distances, the scan line width is about twice the measurement distance (90° FOV).

5.5 Mounting

The linescanner can be installed as follows:

• on a tripod with a standard 1/4-20 UNC (photo equipment) thread. This type of setup requires the optional tripod mounting plate (XXXTMP50ACCC) and is recommended if the linescanner is to be used only for temporary or mobile measurements.

• with the mounting holes of the linescanner housing. This type of setup is recommended for permanent installations where higher stability is desired.

Prevent all contact between heat sources and the linescanner to protect the linescanner from overheating.

5.6 Communication Interfaces

The MP150 can communicate via Ethernet interface or RS485. During system configuration the user selects either Ethernet or RS485. You cannot use Ethernet and RS485 communications for the data transfer at the same time! The Ethernet connection between linescanner and the PC has a maximum speed of 100 MBit/s and permits real-time data transfer for all temperature pixels. For multi-scanner systems you can use a standard Ethernet Switch to connect to the PC network adapter.

5.6.1 Ethernet Wiring

The linescanner is shipped with an Ethernet cable specified to NEMA WC-63.1 Category 5e, UL verified to Category 5e, Ethernet/IP Compliant. This standard cable is 7.5 m (24.6 ft.) long, free from Halogen, and withstands ambient temperatures up to 180°C (356°F). The connector on one cable end (scanner wiring) is an M12 plug-in connector, 4 pin D-coded, suited for industrial Ethernet with IP67 protection rate with a screw retention feature. The connector on the other cable end (field/PC wiring) is an RJ45 connector.

Installation

To establish the Ethernet communication, the subnet addresses for both the scanner and the PC need to match! Appropriate changes can be applied either on the scanner side or on the PC network adapter!

5.6.2 Ethernet Settings

Scanner IP Address

The factory default IP address for the linescanner is 192.168.42.30. The scanners address is not free of choice: It has to be unique in the network meaning that no other device in the network including the PC network adapter may run at the same IP address.

Ask your IT administrator for a free IP address to be used!

Advanced Ethernet Settings

Subnet Mask: The Subnet Mask defines the interpretation of the IP address. The factory default setting is

255.255.255.0. The Subnet Mask can be changed using the <NM> command of the scanner.

Port: In the case that the default scanners port (2727) should conflict with something else (it could be blocked by the firewall for example) it can be changed using the <PO> command of the scanner.

Gateway: A gateway connects two subnets (which have a different subnet address). The IP address of this gateway is given with the route command <RO>. The default is RO0.0.0.0 - this does mean no gateway is set.

MP150 Rev. E3 07/2013 21

Page 22

Installation

The current settings for the IP address and the netmask of the PC can be asked with the

command <ipconfig> in a Command Prompt window!

For the example above, the IP address of the PC is 193.221.142.103. The subnet address is 193.221.142, the host address is 103. The scanner’s subnet address must be 193.221.142 as well. The host address of the scanner must be in the range from 1 to 254 with the exception of 103 which is already used for the PC.

5.6.3 Changing the Ethernet Settings for the PC

The network adapter on the PC side can be configured as following:

1. Go to <Start> <Settings> <Network Connections> <Local Area Connection>

2. Click on <Properties>:

5.6.4 Changing the Ethernet Settings for the Scanner

When using the linescanner on an Ethernet network you may need to change the IP address so that the factory default address does not conflict with another device on the network. Change the IP address following the procedure described below:

• Make sure that the PC network adapter is configured as required, see sections 5.6.2 Ethernet

Settings, page 21 and 5.6.3 Changing the Ethernet Settings for the PC, page 22.

• Make sure that the scanner runtime software DTDP is stopped!

• Switch off the scanner!

• Switch on the scanner!

• Open the Command Prompt window and start a Telnet session by using the command:

telnet <IPAddressScanner> <Port>

Windows 7 does not have Telnet enabled by default. using the command:

• Under Telnet you have access to the scanner command level. Give the new IP address for the scanner with the command:

IP<NewScannerIPAddress>

• With changing the IP address for the scanner you will immediately loose the connection, so you have to restart a further Telnet session by using the new IP address for the scanner:

telnet <NewScannerIPAddress> <Port>

• Save the new IP address permanentely in the scanner with the command:

• Stopp the Telnet session by closing the DOS window. The Ethernet communication will be automatically closed.

5.7 Power Supply Cable

This standard cable is 7.5 m (24.6 ft.) long, free from Halogen, and withstands ambient temperatures up to 180°C (356°F). The linescanner requires a nominal 24 VDC power supply, 18 VDC minimum. To insure that sufficient voltage is supplied t the linescanner, it is necessary to define the gage and the length of the power cable to determine the resistance and the voltage drop. The maximum current draw of the linescanner is 1 A. The following table shows typical parameters from shielded 2 wire copper cables and the maximum recommended cable length.

Tab. 1: Maximum allowed cable length from a 24 VDC power supply to the linescanner

The linescanner is equipped with an electronic fuse to prevent damage from voltage spikes greater than 36 V on power or signal lines. If the fuse circuit switches the power off, disconnect the power line for several seconds and turn power on again.

5.8 Warm-Up time

For accurate temperature readings we recommend a 30 minute warm-up period after power on. During this time the internal calibration sources will be stabilized. Digital communication and the analog outputs can be started 60 seconds after power on.

5.9 Water Cooling

The linescanner is equipped with integrated stainless-steel pipes for water cooling. These pipes are embedded in the cast aluminum housing. The water cooling system enables the linescanner to be installed in ambient temperatures up to 180°C (356°F). Maximum pressure for the cooling fluid is 15 bar (218 PSI). Only filtered water should be used in order to reduce the risk of clogging at the hose couplings. In order to prevent the accumulation of water condensation on the scanner window and to protect the window, the air purge system should always be used when water cooling is used. Threaded tube fittings to connect a water cooling system are provided as accessory, see section

7.4 Tube Fittings, page 37. The internal stainless steel tube is designed to mate to a hose with an internal diameter of 6 mm (0.24 in.).

The following table gives some examples for the efficiency of the water cooling system.

Tab. 2: Efficiency of the water cooling system

5.9.1 Avoiding Condensation

If environmental conditions make water cooling necessary, it is strongly recommended to check for condensation on the interior of the scanner housing. Water cooling also cools the air in the interior of the scanner housing thereby decreasing the capability of the air to store water. The relative humidity increases and can reach 100% very quickly. In case of additional cooling, the surplus water vapor will precipitate out as water (condensation) that will condense on the lenses and the electronics thereby causing device failure. Condensation can even occur with an IP65 sealed housing.

The presence of condensed water inside the housing will void the warranty!

There are several ways to prevent condensation:

1. Adjust the flow rate and check visually for moisture on the exterior of the housing. This method has a degree of risk if the moisture is not detected quickly.

2. Use a radiator or heat exchanger where the cooling fluid can be heated above the dew point.

3. Measure the ambient temperature and the relative humidity where the device has to be installed. Use the table below to get the minimum device temperature. If the temperature of the cooling fluid is much lower than the minimum device temperature, condensation can be expected. To avoid this, adjust the flow rate manually or use a thermostat to keep the device at a minimum temperature above the dew point.

The use of a thermostat is strongly recommended, see section 7.5 Thermostat, page 38!

5.10 Air purge collar

The air purge system produces a laminar air flow that protects the linescanner window from dust, moisture, and vapor. The air flows from the couplings through the walls of the housing and through side slits near the scanner’s window. The air flow should be between 100 l/min (3.53 cfm) and 200 l/min (7.06 cfm) through each side, which corresponds to a pressure between 0.5 bar (7.25 psig) and

3.0 bar (43 psig) when using the supplied metric fittings. The inside diameter for the air hose should be 4 mm (0.16 in.). The hose couplings for the air purge system are connected to the housing through ISO 228 G 1/8” stainless steel fittings.

Operation

Scan

Target direction Speed = 2 m/s

Distance between the actual measured lines (d), as output, is a function of the optical scan rate, line averaging and target speed.

Optical scan rate = 150 Hz

Each revolution = 6,6 ms Target viewed for 1,6 ms Internal calculations occur for 5 ms

Example

Snapshot Mode Target speed = 2 meters/sec (78.7 in.) Distance between measured lines is given by the following formula:

i.e., During 100% mirror rotation, which takes 6,6 ms, target moves d = 0.013 m (0.51 in.)

6.1 Scan Rate and Target Viewing Time

During 25% mirror rotation (target viewing time), which takes 1,6 ms, target moves d1 = 0.003 m (0.12 in.) During 75% mirror rotation (internal calibration time), which takes 5 ms, target moves d2 = 0.01 m (0.4 in.)

6.2 Sectors

The linescanner is equipped with three analog outputs. Each output can be assigned to a ”sector” within the 90° scan angle. For each sector, the type of output (maximum, minimum, or mean value) can be selected. The output range can be configured for either 0 ... 20 mA, 4 ... 20 mA, or custom configured by user settings. The sector size and the emissivity value can be set for each sector, even if the sectors overlap. (In the case of overlapping sectors, the higher emissivity is given priority.) To use the sector function, the linescanner must run in the continuous mode.

Use the Configurator of the scanner software to configure the analog outputs!

• The maximum size of a sector is 90°.

• The corresponding analog output will remain inactive if the sector size is 0.

• Each sector can have either a maximum, minimum, or mean output value.

• Each sector is assigned to an analog interface.

• The output range can be adjusted to any value between 0-20mA.

• The analog interfaces are potential-free, but have a common ground connection

6.3 Data Transfer Modes

After each scan, the temperature values are transferred through the serial or the Ethernet interface to a computer. This computer will require either DataTemp software or custom software for data analysis. The data transfer can be achieved through one of two methods (selected by the user):

• Snapshot mode (discontinuous mode): The lines are scanned at the set sampling rate and are

subsequently stored in the internal memory of the linescanner (capacity: 700 lines). After completing the snapshot, all lines are transferred through the digital interface. When measuring discrete objects, it may be advantageous to use the trigger input of the linescanner to initiate the image capture. The trigger signal can be generated by a voltage/switch indicating the approach of an object from the production process into the linescanner field-of-view, see section 5.11 Input

and Output Connectors on page 29 for more information.

• Image mode (continuous mode): One line is scanned and transferred through the digital

interface immediately. The duration of the data transfer is determined by the maximum interface speed. These factors determine whether every line is transferred.

6.4 Scanner as Stand-Alone Device

The scanner is equipped with internal sectors supporting three analog outputs and the alarm relay. To configure the scanner as stand-alone device without having a computer software running follow the steps given below:

1. Launch the DTDP Configurator.

2. Configure the scanner’s standard settings like scan speed and pixel count.

3. Configure the internal sectors on the Configurator’s <Device Sector> page.

Please note, the software sectors under the <Sector> page are not supported with a scanner in the stand-alone mode.

The DTDP software sends a <PS> command automatically to the scanner if at least one scanner internal sector is detected.

4. Launch the DTDP software one times to transfer all the parameters into the scanner. Afterwards, the DTDP software can be exit and the scanner runs as stand-alone device.

7.8 RS485 Interface Kit

The RS232/485 interface provides a serial data transfer to the PC. However, the PC will have to be capable of communicating at a sufficiently high baud rate. Most standard PC’s communicate at speeds up to 115 kBaud which is capable of communication with the linescanner at a scan speed of 36 Hz and at 256 pixel per scan data sampling rate. For faster scan frequencies or for a higher pixel count the Ethernet connection should be used.

The RS485 Interface Kit comes with 7.5 m (25 ft) long RS485 cable (for ambient: 180°C/356°F: XXXTMP50S485CB, for ambient: 60°C/140°F: XXXTMP150S485CBLT), RS232/485 converter and RS232 adapter cable 25 to 9-pin.

To use the RS232/485 connection, connect the linescanner to the PC with the RS485 cable. First, insert the 7-pin DIN-round plug (IP65) into the socket on the back side of the linescanner, then tighten the

8.1 Cleaning the Window

The linescanner’s window must be kept as clean as possible. Any foreign matter on the window will affect the accuracy of the measurements. Take care when cleaning the window as it can easily be scratched. Please observe the following guidelines:

• Lightly blow off loose particles.

• Gently brush off remaining particles with a soft camel hair brush.

• Clean remaining dirt using a soft cotton cloth dampened in distilled water. Don’t rub.

• To remove finger prints or other grease, gently wipe with a soft cloth dampened in a mild

soap or distilled water (or ethanol or alcohol) solution.

• You should avoid getting any liquid in areas surrounding the window material.

8.2 Replacing the Window

1. Remove the 4 hex screws on the back side using a 2.5 mm allen wrench. Slide the collar forward to separate it from the housing!

Figure 32: Removing the air purge collar

2. Remove the 4 hex screws on the front side separating the window frame from the housing. Separate the window from the frame!

3. The window assembly consists of a frame (holder), the window material (mica) and a gasket.

The gasket lies close to the housing, followed by the window material. If necessary, exchange the window material. Window size: 114 x 60 mm (4.49 x 2.36 inches).

10.1 Determination of Emissivity

Emissivity is a measure of an object’s ability to absorb and emit infrared energy. It can have a value between 0 and 1.0. For example a mirror has an emissivity less of 0.1, while the so-called “Blackbody“ reaches an emissivity value of 1.0. If a higher than actual emissivity value is set, the output will read low, provided the target temperature is above its ambient temperature. For example, if you have set

0.95 and the actual emissivity is 0.9, the temperature reading will be lower than the true temperature. An object’s emissivity can be determined by one of the following methods:

1. Determine the actual temperature of the material using an RTD (PT100), a thermocouple, or any other suitable method. Next, measure the object’s temperature and adjust emissivity setting until the correct temperature value is reached. This is the correct emissivity for the measured material.

2. For relatively low temperatures (up to 260°C, 500°F) place a plastic sticker on the object to be measured. This sticker should be large enough to cover the target spot. Next, measure the sticker’s temperature using an emissivity setting of 0.95. Finally, measure the temperature of an adjacent area on the object and adjust the emissivity setting until the same temperature is reached. This is the correct emissivity for the measured material.

3. If possible, apply flat black paint to a portion of the surface of the object. The emissivity of the paint must be above 0.95. Next, measure the temperature of the painted area using an emissivity setting of 0.95. Finally, measure the temperature of an adjacent area on the object and adjust the emissivity until the same temperature is reached. This is the correct emissivity for the measured material.

10.2 Typical Emissivity Values

The following table provides a brief reference guide for determining emissivity and can be used when one of the above methods is not practical. Emissivity values shown in the table are only approximate, since several parameters may affect the emissivity of a material. These include the following:

1. Temperature

2. Angle of measurement

3. Geometry (plane, concave, convex)

4. Thickness

5. Surface quality (polished, rough, oxidized, sandblasted)

6. Spectral range of measurement

7. Transmissivity (e.g. thin films plastics)

Tab. 8: Typical Emissivity Values

To optimize surface temperature measurements, consider the following guidelines:

• Determine the object emissivity using the instrument which is also to be used for the measurements.

• Avoid reflections by shielding the object from surrounding temperature sources.

• For higher temperature objects use instruments with the shortest wavelength possible.

• For translucent materials such as plastic foils or glass, assure that the background is uniform

and lower in temperature than the object.

• Mount the sensor perpendicular to surface whenever emissivity is less than 0.9. In all cases, do not exceed angles more than 30 degrees from incidence.
