The size of the measuring object and the optical resolution of the infrared thermometer
determine the maximum distance between sensing head and measuring object.
In order to prevent measuring errors the object should fill out the field of view of the optics
completely.
Consequently, the spot should at all times have at least the same size like the object or should
be smaller than that.

2.4 Optics

The vario optics of the CSvideo allows a smooth focusing of the optics to the desired distance. The sensors
are available in two optic versions:

The following tables show the diameter of the measuring spot for some selected distances. The spot size
refers to 90 % of the radiation energy.
The distance is always measured from the front edge of the sensing head.

As an alternative to the optical diagrams, the spot size calculator can also be used on the optris website

5 Electrical Installation

5.1 Cable Connections

The CSvideo has two connector plugs integrated in the sensor backplane.
Therefore an opening of the sensor for cable assembling is not necessary.
For connection to a PC you can use the supplied 5 m USB cable with a
4-pin sensor connector (lengths of 10 m and 20 m are optional available).

For the analog connection (4-20 mA current loop, alarm, laser) a cable with
a 7-pin plug is needed. This cable is not included in the scope of
supply and has to be ordered separately.
Lengths of 3, 8 and 15 m are available.
Please use the original ready-made, fitting connection cables.

5.2 Power supply

Please use a separate, stabilized power supply unit with an output voltage of 5–30 VDC which can supply
100 mA. The ripple should be max. 200 mV.

Please use shielded cables only for all power and data lines.
The sensor shield has to be grounded.

5.3 Analog Mode

If the CSvideo is used as analog device the sensor provides beside the 4-20 mA signal in addition an alarm
output (open-collector). To activate the alarm output and set the alarm threshold value the software is
needed.

The supply line for the sighting laser must be led via a switch or pushbutton, which has to be
installed max. 2 m away from installation site of the sensor.

With a laptop or tablet PC, the sensor parameterization and alignment can be carried out on site. The USB
cable can be plugged into the sensor during operation (hot plug & play).

-Electrical Installation 23-

5.4 Digital Mode

In the digital mode the sensor and the laser will be powered via the 5 V from USB interface. The activation/
deactivation of the laser has to be made via the software.

The sensor is offering two ways of digital communication:

 bidirectional communication (sending and receiving data)
 unidirectional communication (burst mode – the sensor is sending data only)

-24 -

5.5 Maximum Loop Impedance

The maximum impedance of the current loop depends on the supply voltage level:

-Sighting 25-

WARNING: Do not point the laser directly
at the eyes of persons or animals!
Do not stare into the laser beam. Avoid
indirect exposure via reflective surfaces!

The laser should only be used for sighting and positioning of the sensor. A permanent use of the laser can
reduce the lifetime of the laser diodes and also the measurement accuracy can be affected.

6 Sighting

The CSvideo has an integrated video camera which is using the same optical channel than the IR detector.
In addition the sensor has a cross laser aiming which marks the center of the measurement spot at any
distance. The combination of video and laser sighting enables a perfect alignment of the sensor to the
object.

The supply line for the sighting laser must be led via a switch or pushbutton, which has to be
installed max. 2 m away from installation site of the sensor.

The laser can be activated/ deactivated via this switch (which needs to be installed by the user) or via the
software.

At ambient temperatures >50 °C the laser will be switched off automatically.

-26 -

6.1 Focusing and Video Sighting

On the back plane of the sensor you will find a rotary button for focusing of the
optics.
To set the focus to the desired measurement distance you have to connect
the sensor with a PC using the USB cable. Please start the CompactConnect
software. You will see the video beside the temperature-time diagram. The
position of the measurement spot is indicated by a circle inside the video
picture. The size of this circle is equivalent to the IR spot size.

By turning the rotary button clockwise you will change the focus in direction far. By turning
counterclockwise you will change the focus in direction close.

After a successful focusing please enter the measurement distance (distance sensor front – object) in the
according field in the software (underneath the video picture).

You will find a detailed description of the video
settings in the software description which you can
call via the menu [?/ Help...].

8 Basics of Infrared Thermometry

Depending on the temperature each object emits a certain amount of infrared radiation. A change in the
temperature of the object is accompanied by a change in the intensity of the radiation. For the measurement
of “thermal radiation” infrared thermometry uses a wave-length ranging between 1 µm and 20 µm.
The intensity of the emitted radiation depends on the material. This material contingent constant is described
with the help of the emissivity which is a known value for most materials (►9 Emissivity).

Infrared thermometers are optoelectronic sensors. They calculate the surface temperature on the basis of
the emitted infrared radiation from an object. The most important feature of infrared thermometers is that
they enable the user to measure objects contactless. Consequently, these products help to measure the
temperature of inaccessible or moving objects without difficulties. Infrared thermometers basically consist of
the following components:

 lens
 spectral filter
 detector
 electronics (amplifier/ linearization/ signal processing)

The specifications of the lens decisively determine the optical path of the infrared thermometer, which is
characterized by the ratio Distance to Spot size.
The spectral filter selects the wavelength range, which is relevant for the temperature measurement. The
detector in cooperation with the processing electronics transforms the emitted infrared radiation into electrical
signals.

-Emissivity 31-

9 Emissivity

9.1 Definition

The intensity of infrared radiation, which is emitted by each body, depends on the temperature as well as on
the radiation features of the surface material of the measuring object. The emissivity (ε – Epsilon) is used as
a material constant factor to describe the ability of the body to emit infrared energy. It can range between 0
and 100 %. A “blackbody” is the ideal radiation source with an emissivity of 1,0 whereas a mirror shows an
emissivity of 0,1.
If the emissivity chosen is too high, the infrared thermometer may display a temperature value which is much
lower than the real temperature – assuming the measuring object is warmer than its surroundings. A low
emissivity (reflective surfaces) carries the risk of inaccurate measuring results by interfering infrared radiation
emitted by background objects (flames, heating systems, chamottes). To minimize measuring errors in such
cases, the handling should be performed very carefully and the unit should be protected against reflecting
radiation sources.

9.2 Determination of unknown Emissivities

► First, determine the actual temperature of the measuring object with a thermocouple or contact sensor.

Second, measure the temperature with the infrared thermometer and modify the emissivity until the
displayed result corresponds to the actual temperature.

► If you monitor temperatures of up to 380 °C you may place a special plastic sticker (emissivity dots – part

number: ACLSED) onto the measuring object, which covers it completely. Now set the emissivity to 0,95

-32 -

and take the temperature of the sticker. Afterwards, determine the temperature of the adjacent area on
the measuring object and adjust the emissivity according to the value of the temperature of the sticker.

► Cove a part of the surface of the measuring object with a black, flat paint with an emissivity of 0,98. Adjust

the emissivity of your infrared thermometer to 0,98 and take the temperature of the colored surface.
Afterwards, determine the temperature of a directly adjacent area and modify the emissivity until the
measured value corresponds to the temperature of the colored surface.

CAUTION: On all three methods the object temperature must be different from ambient temperature.

9.3 Characteristic Emissivities

In case none of the methods mentioned above help to determine the emissivity you may use the emissivity
tables ►Appendix A – Emissivity Table Metals and Appendix B – Emissivity Table Non Metals. These
are average values, only. The actual emissivity of a material depends on the following factors:

 temperature
 measuring angle
 geometry of the surface
 thickness of the material
 constitution of the surface (polished, oxidized, rough, sandblast)
 spectral range of the measurement
 transmissivity (e.g. with thin films)

Appendix C – Smart Averaging

The average function is generally used to smoothen the output signal. With the adjustable parameter time
this function can be optimal adjusted to the respective application. One disadvantage of the average function
is that fast temperature peaks which are caused by dynamic events are subjected to the same averaging
time. Therefore those peaks can only be seen with a delay on the signal output.
The function Smart Averaging eliminates this disadvantage by passing those fast events without averaging
directly through to the signal output.
