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 30 C/R

•

It must be installed in a housing that has the protection category IP20 or better according
to DIN IEC 60529. 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 in zone 0, 1 and 2.

•

It must be supplied by an intrinsically safe power supply unit or a Zener barrier placed
outside of the potentially explosive 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 class. For detailed information refer to the section about the
temperature data for potentially explosive areas on page 42

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!

14

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.

5.1 Configuration with a PC

DANGER!

Never establish a connection between a PC and a transmitter if one of them is within a
potentially explosive area. Otherwise the PC or the transmitter might cause an explosion that
can result in fatal injuries. If you want to configure the transmitter with the help of a PC, assure
that both of them are not in a potentially explosive area.

DANGER!

If you want to configure a transmitter with an Ex approval with the help of a PC, always use an
ATEX certified cable. Never configure the transmitter when in hazardous area or when
connected to a sensor located in hazardous area.

CAUTION!

Only use the manufacturer's configuration kit for PC configuration. Another configuration kit
could destroy or damage the transmitter.

DANGER!

Always put the cover on the transmitter programming connector when not used.
If the transmitter is not properly installed, the programming connector can get energized and
cause electrical shock.

OPERATION 5

The configuration of the transmitters works with a PC and the manufacturer's
PC configuration kit (for further information refer to
PC nor the transmitter (including its sensor) is within a potentially explosive area, you can carry
out the configuration "online" (i.e. the transmitter can remain in operation during the
configuration and you have access to all functions). During configuration, the output is "frozen"
and the transmitter continues to work with the last value. As soon as the configuration has been
completed, the transmitter uses the new parameters.

If you want to configure the transmitter with a PC, the following conditions have to be fulfilled:

• The transmitter must be connected to a power supply. For further information refer to the

chapter "Electrical connection".

• The software "TempSoft" has to be installed on your PC. For further information refer to the

manual "TempSoft". The current version of the software and the manual "TempSoft" are
available in the download area on the manufacturer's website.

• You have available the manufacturer's PC configuration kit which contains a

configuration cable and an adapter cable.

• Maximum common-mode voltage on the input is restricted to 50 VAC / 75 VDC.

To configure the in-head version (Ex and Non-Ex) you just need the configuration cable with the
adapter cable; to configure the rail-mount version, you only need the configuration cable. For
further information refer to the following illustrations:

5 OPERATION

5.3 SmartSense function

The in-head transmitter uses the measuring sensors (needs one additional wire in sensor) to
monitor permanently the isolation resistance of the sensor and of the sensor leads. This function
is called "SmartSense" and it is possible in combination with a sensor of the type Pt100 (3-wire
connection) and with thermoelements. The "SmartSense" function is important because an
isolation resistance which is too low creates an incorrect measuring value and thus a faulty
output.

If the transmitter shows a low isolation resistance, the "SmartSense" function allows to set the
output to a predefined value. You can set the function with the help of the PC configuration
software, in the Input tab, select:
Connection: 3w+Low Isolation for Pt100 or Cold Junction Comp.: Yes+Low Isolation for
thermocouple.

5.4 Temperature difference measurement

The transmitters are able to measure the temperature difference between two 2-wire connected

Pt100 sensors, T1 – T2. T1 must always be equal or greater than T2. Select this function in the

connection window of the input folder.

OPTITEMP TT 30 C/R

For temperature difference measurements you have to deactivate the sensor break function, i.e.
it must have the setting "Sensor break = None". You can set the function with the help of the
PC configuration, for further information refer to

5.5 Sensor break monitoring

The transmitter is able to determine a sensor break/short circuit with the help of a pulse signal.
This signal may interfere with electronic temperature calibrators. To switch off the pulse signal,
you have to choose the setting "Sensor break = None". You can set the function with the help of
the PC configuration, for further information refer to

7 TECHNICAL DATA

7.1 Measuring principles

The kind of the measuring principle depends on the measuring insert that you combine with the
transmitter. In matters of the thermometer type the manufacturer offers two different
measuring inserts, either with a resistance thermometer or with a thermocouple. For more
information refer to the handbook of the measuring inserts or the handbook of the industrial
thermometers.

7.1.1 Resistance thermometer

The measuring insert with a resistance thermometer 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.

OPTITEMP TT 30 C/R

-3K-1

in the range from 0...+100°C/

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).

OPTITEMP TT 30 C/R

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 which is then 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 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.

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.

sensor from the standard curve).

precondition is that the sensor has been exposed to one (one-point correction) or
two (two-point correction) accurately measured temperatures ("true
temperatures"); after you have entered these true temperature(s), the transmitter
automatically corrects these errors afterwards.

This function continously monitors the isolation resistance of thermocouples and 3­wire connected RTDs as well as the cabling between sensor and transmitter; if the
isolation is too low, the transmitter forces the output to a user-defined level; note
that SmartSense requires an extra lead inside the thermocouple or RTD.
