Compact temperature transmitter Wika TFT35

Date: 26 June 2018
WIKA, a supplier of measuring instruments and accessories, presented compact temperature transmitter Wika TFT35. Within the refrigeration cycle and its periphery there are many points where pressure, temperature and level are measured and monitored. In view of the increasing requirements on refrigeration plants due to new refrigerants or leak-free systems the quality requirements for measuring instruments are also increasing.

Special features

    • Measuring ranges from -50 ... +200 °C (-58 ... +392 °F)
    • Electrical connection via plug connection
    • Output signal 4 … 20 mA, 0 … 10 V or 0.5 … 4.5 V
    • Factory configured
    • Measuring insert exchangeable


The model TFT35 compact temperature transmitter is used for temperature measurement of liquid and gaseous media in the range -50 ... +200 °C (-58 ... +392 °F).

It can be used for pressures up to 40 bar. All electrical components are protected against splash water and are designed to withstand vibration.

The integrated thermowell with fixed threaded connection or adjustable compression fitting enables direct installation into the process. All wetted parts and also the case are from stainless steel.

The case and the exchangeable measuring insert are screwed together using a knurled nut. This enables the exchange of the measuring insert without having to remove the instrument from the process.

Through the integrated connector, simple installation of the transmitter is ensured.

The integrated electronics convert the temperature-dependent resistance signal of the measuring element into a linear unit signal. For the signal outputs, 4 ... 20 mA, 0 ... 10 V and also 0.5 ... 4.5 V ratiometric are available.
