3. Regulation Use
The Temperature Sensor, model: TSA, is to be installed only in the specified
applications. Any usage which exceeds the specifications may invalidate its
warranty. Therefore any resulting damage is not the responsibility of the
manufacturer. The user assumes all risk for such usage. The application
specifications include the installation, start-up and service requirements specified
by the manufacturer.
4. Operating Principle
Model TSA Temperature Sensors respond quickly and are designed to work from
-40 to +150 °C. The measuring device is a laser-trimmed electronic sensor
enclosed in a sturdy brass or stainless steel housing and is suitable for harsh
industrial applications.
Laser trimming allows a high output signal at the temperature sensor to be
achieved with respect to the measured temperature change. This system means
that no line compensation is required for cabling under 20 meters.
This relationship is linear with positive temperature coefficients. For evaluation of
the output signal control and indicating instruments, which allow a flexible
application in a wide range of installations, are being used.
The sensors come in a housing with female threaded connections on both sides
(G 1/4” to G 1 1/2”) and a 1.5 m connection cable with a silicone jacket.

5. Instrument Inspection
Instruments are inspected before shipping and sent out in perfect condition.
Should the damage to a device be visible, we recommend a thorough inspection
of the delivery packing. In case of damage, please inform your parcel service/
forwarding agent immediately, since they are responsible for damages during
transit.
Scope of supply:
The standard delivery includes the following:
• Temperature sensor model: TSA
• Operating instructions
6. Mechanical Connection
Before installation:
• Remove all packing materials and transport retainers and ensure that no such
materials remain in the device.
• Make sure that the maximum operating pressures and temperatures will not be
exceeded in the intended installation of the device (see “Technical
Information”).
• Install the temperature sensor tension-free in the piping.
• This device must not be installed within an induction field.
• If possible, after completing the mechanical installation, immediately check the
threaded connection between the device and the piping for leakage.
7. Electrical Connection
The temperature sensor is connected with a two-wire silicone cable. The polarity
of the connection does not matter.

10. Maintenance
This temperature sensor is maintenance-free. If it is necessary to remove
accumulated dirt, loosen the sleeve nut and remove the sensor for cleaning.
Caution! Before removing the sensor, be sure to relieve the pressure in the
piping and drain it of fluid.
