3 INSTALLATION

3.1 Notes on installation

INFORMATION!

Inspect the cartons carefully for damages or signs of rough handling. Report damage to the carrier and to the local office of the manufacturer.

INFORMATION!

Do a check of the packing list to make sure that you have all the elements given in the order.

INFORMATION!

Look at the device nameplate to ensure that the device is delivered according to your order.

3.2 In-head transmitter (Ex and Non-Ex)

DANGER!

Never install or operate the Non-Ex version in potentially explosive areas, it might cause an explosion that can result in fatal injuries! Only use the Ex version in potentially explosive areas! Also note the following items which concern the Ex version:

OPTITEMP TT 10 C/R

•

It must be installed in a housing that has the protection category IP20 or better according to DIN IEC 60529 (an exception are in-head transmitters mounted on a rail as described in the next section). Additionally the magnesium component of the housing must not exceed 6% as a higher magnesium component may increase the flammability and the Ex capability.

•

If it is mounted in a housing which is isolated from the ground and can be charged to an ignition capable level, then the housing must be electrostatically grounded when installed in hazardous areas.

•

It is approved for potentially explosive areas (zone 0).

•

It must be electrically connected (terminal 4 and 5) via a certified isolating interface/zener barrier having double or reinforced insulation which shall be placed outside the hazardous area.

CAUTION!

The manufacturer has developed the Non-Ex version for an operating temperature range of

-40...+85

C / -40...+185°F (the Ex version has the same ambient temperature range). To avoid destruction or damage of the device, always assure that the operating temperature or the ambient temperature does not exceed the permissible range and note the following items:

•

If you operate the Ex version in potentially explosive areas, the ambient temperature also depends on the temperature classification. For detailed information refer to the section about the temperature data for potentially explosive areas on page 46

The thermowell also transfers the process temperature to the transmitter housing. If the

•

process temperature is close to or exceeds the maximum temperature of the transmitter, then the temperature in the transmitter housing can rise above the maximum permissible temperature!

www.krohne.com 02/2013 - 4000752703 - MA OPTITEMP TT 10 C/R R03 en

Page 17

OPTITEMP TT 10 C/R

One way to decrease the heat transfer via the thermowell is to install the transmitter farther away from the heat source. An alternative is to make the thermowell longer. Inversely you can take similar measures if the temperature is below the specified minimum temperature.

The in-head transmitters (Ex and Non-Ex version) are intended for installation in DIN B connection heads or larger. The large Ø7.5 mm / 0.29" center hole facilitates the electrical connection of the measurement sensor and the installation (for detailed information refer to the chapter "Dimensions and weights"). The following drawing shows the installation of the in-head transmitter with the help of the connection head installation kit:

5.1 Configuring the in-head version

DANGER!

To avoid electric shocks and destructions or damages of the device, assure that all electrical connections comply with the instructions within the chapter "Electrical connections".

DANGER!

Only perform the configuration described in this section if no sensor is connected to the transmitter. Otherwise you could damage the cable insulation during soldering, furthermore the cables could handicap during soldering.

INFORMATION!

•

The steps in this section show the complete configuration procedure in the correct order for new transmitters. The manufacturer strongly recommends to follow this procedure, otherwise the calibration may not be proper.

•

As an option the manufacturer offers preset transmitters according to the customer's order. Only in this case the solder pad configuration and potentiometer adjustment is not necessary.

•

In some cases you have to change the solder pad configuration and perform a new potentiometer adjustment of a transmitter that has already been in use. This may be the case e.g. if you must define a new zero point or measuring span for a new application.

CAUTION!

You have to choose one sensor break configuration, i.e. you may only set one of the two solder jumper! If you establish both solder jumper connections, this could lead to damage or destruction of the transmitter.

Step 4: setting the sensor break monitoring

1 Lower solder jumper: the output signal for sensor break is in this case ≤ 3.6 mA 2 Upper solder jumper: the output signal for sensor break is in this case ≥ 23 mA

CAUTION!

After the solder pad configuration of the sensor break monitoring is complete, assure that the cover is on its original place again! The cover prevents electrostatic discharge if the solder pads are touched inadvertently; furthermore it protects the solder pads against dirt.

The setting of the sensor break monitoring is the last step in the configuration procedure. After the configuration is complete, a calibration and an adjustment of the potentiometers is necessary to achieve correct measuring results.

5.7 Calibration

DANGER!

To avoid electric shocks and destructions or damages of the device, assure that all electrical connections comply with the instructions within the chapter "Electrical connections".

INFORMATION!

The manufacturer recommends checking the calibration annually. To achieve the best possible accuracy, note the following items:

•

All calibration instruments (i.e. resistance decade and amperemeter) must have an accuracy of at least 0.02%.

•

Assure that the complete solder pad configuration has taken place before the calibration.

•

The calibration has to take place according to the temperature scales ITS 90 (IEC 60751 for Pt100, IEC 60584 for thermocouple type J, K, N and T and DIN 43710 for thermocouple type L). The simulation source for RTD input on the transmitter must have a temperature coefficient setting for platinum (= 0.00385). The simulation source for thermocouple input on the transmitter must have the selected thermocouple type and used with correct thermocouple wire that is connected with the correct polarity.

•

If you set an input signal that delivers an outputs signal of 12 mA as described in the following actionsequence, wait about 15 minutes and check the stability of the output signal afterwards. Only if the output signal is stable then, the transmitter is ready for calibration.

7.1 Measuring principle

7.1.1 Resistance thermometer

The transmitter works together with a measuring insert that has a Pt100 RTD. This kind of measuring inserts features a temperature-sensitive sensor made from a platinum RTD, whose

value at 0°C / +32°F is 100 Ω. That is where the name "Pt100" comes from.

It is generally valid that the electric resistance of metals increases according to a mathematical function as the temperature rises. This effect is taken advantage of by resistance thermometers to measure temperature. The "Pt100" thermometer features a measuring resistance with defined characteristics, standardised in IEC 60751. The same is true for the tolerances. The

average temperature coefficient of a Pt100 is 3.85 x 10

+32...+212°F.

During operation, a constant current I (≤ 1 mA) flows through the Pt100 RTD, which brings about a voltage drop U. The resistance R is calculated using Ohm's Law (R=U/I). As the voltage drop U

at 0°C / +32°F is 100 mV, the resulting resistance of the Pt100 thermometer is 100 Ω (100 mV /

1 mA = 100 Ω).

7 TECHNICAL DATA

7.1.2 Thermocouples

The thermocouple features two electric conductors made from different metals, connected at one end. Each free end is connected to a compensation cable extension or direct connected to a millivolt meter. This circuitry forms a "thermal circuit". The point at which the two electric conductors connect is called the measuring point or hot junction and the point at which the compensation cables connect to the conductors of the millivolt meter is called the cold junction.

If the measuring point of this thermal circuit is heated up, a small electrical voltage (thermal voltage) can be measured. If, however, the measuring point and the cold junction are at the same temperature, no thermoelectric voltage is generated. The degree of thermoelectric voltage, also known as electromotive force (EMF), depends on the thermocouple material and the extent of the temperature difference between the measuring point and the cold junction. It can be measured using the millivolt meter with no auxiliary power.

Compensation cable has the same thermoelectric behavior as the thermocouple in a limited temperature range.

Extension cable is a thermocouple but designed as an installation cable.

OPTITEMP TT 10 C/R

Simply put, the thermocouple behaves like a battery, the voltage of which also increases as the temperature rises.

INFORMATION!

The characteristic curves and tolerances of commercially available thermocouples are standardised in IEC 60584.
