1.1 Intended use
CAUTION!
Responsibility for the use of the measurement devices with regard to suitability, intended use
and corrosion resistance of the used materials against the measured fluid lies solely with the
operator.
INFORMATION!
The manufacturer is not liable for any damage resulting from improper use or use for other than
the intended purpose.
The compact sensors are used to measure the temperature of gases, liquids, vapour and solids
in industrial applications with limited installation space. The devices are particularly suited to
the measurement of
• liquids with low viscosity
• water and chemicals with low corrosiveness

2.2.1 Design of the compact sensors
INFORMATION!
In this documentation, the term "compact sensor" refers to all temperature assemblies
featuring with/without built-in transmitter.
OPTITEMP TRA-CXX
Figure 2-1: Design of all compact sensors
1 Electrical connection
2 Housing
3 Process connection
4 Thermowell
OPTITEMP compact sensors consist of a measuring probe with a process connection and a neck
tube with an electrical connection at the end. The sensors are avaiable with a built in
transmitter.
The transmitter linearizes to measured value to a 4… 20mA output and has a built in failure
mode, loop.

2 DEVICE DESCRIPTION
2.2.3 Types of temperature transmitters
Electrical temperature assemblies have just one, weak, interference-prone output signal. If this
signal has to travel a great distance or if a standard signal of 4...20 mA is required, use of a
temperature transmitter is recommended:
INFORMATION!
The manufacturer cannot make any general statement as to the distance from which the use of a
temperature transmitter is necessary as it depends on the specific interference associated with
the installation site. The operator alone is responsible for this decision.
There are two types of temperature transmitters:
• Built-in transmitter: Located in the housing of the temperature assembly
• Rail-mounted transmitter: Located in the control cabinet or field housing, recognisable by
the "R" in the product name (e. g. TT 50 R); they are usually used when the temperature in the
connection head does not allow for the use of a head-mounted transmitter
Built in transmitters
Built in transmitters
Built in transmittersBuilt in transmitters
OPTITEMP TRA-CXX
The built-in transmitters convert the temperature sensor's small signal into a standardised
output signal of 4...20 mA, not susceptible to interference. Which built in transmitter that is used
depends on the choice of the sensor.
The temperature range is set at factory:
• 0... +100°C / +32... +212°F
• -50... +150°C / -58... +302°F
Other temperature ranges are available on request.

You can parameterise almost any temperature transmitter using a PC and a computer program.
The only exceptions are the TT 10 R and TT 11 R versions, whose measuring ranges must be set
using solder bridges. The following temperature transmitters are currently available:

INFORMATION!
Consult the relevant transmitter handbook for more detailed information on the rail mountesd
temperature transmitters.
2.2.4 Housing
The housing connects the process connection (i.e. screw socket or flange) to the electrical
contact. Its function is to thermally decouple the connection and transmitter so the ambient
temperature doesn't exceed the permissible limits.
The materials of the housing and the thermowell are identical.
2.2.5 Thermowells
The thermowell is designed to prevent external loads (e. g. static pressure, flowing and
aggressive media) from damaging the sensor element. As a rule, the thermowell is made of the
same material as the system in which the measuring is done. The thermowell is built up from
multiple part and welded together.

2.3 Process connections and areas of application
2.3.1 Threaded sensor
The gas tight threaded process connection is suitable for general applications with none or low
pressure. Can be mounted on pipes or tanks like in the chemical industry and into a solid part as
in the equipment industry. Depending on the application there are several types of threads and
standards to consider.
2.3.2 Flange sensor
The ISO 2852 Stainless steel clamp is a pipe coupling for the food and beverage industry. It is an
international standard defining a non-permanent hygienic piping interconnect method. Mainly
used in the food processing industry and with dairy farm equipment. The connection is built up
with a flange on the instrument and a counter flange in the pipe or tank. Between the flanges a
polymer sealing gasket fitting is placed. An enclosing clamp covers the outer circumference of
the flange to squeeze the two flanges together and with help of the gasket make a tight and solid
connection.
This clamp connection makes it easy to connect and disconnect without any special tools,
suitable for processes where continues cleaning is required like the food and beverage industry.
Companies that supply products according to the specifications of ISO 2852 do not necessarily
mention the ISO standard as such, instead referring to the equipment by terms common in the
relevant industries or applications like Tri-clamp or S-clamp.
