SITRANS TF is used where other transmitters can't cope. One main point is its rating of IP67.

SITRANS TF is made of rugged die cast aluminum or long-lasting stainless steel. It transforms resistance thermometers, thermocouples, Ohm and mV signals into a load independent DC current corresponding to sensor characteristic or a digital signal according Fieldbus standard Profibus PA or Foundation Fieldbus. The remote mounted sensor prevents the transmitter heating up at high temperature; there are no vibrations and oscillations due to long neck tubes and protective pipes with SITRANS TF.

For tags with difficult access to you can mount your SITRANS TF remotely at easily accessible places and display the measured value on the freely programmable digital display (with version 4 to 20 mA).

You can even use the SITRANS TF in a version without a transmitter as a comfortable field display unit for all 4 to 20 mA signals. 
All SITRANS TF are available in intrinsically safe or explosion proof version

Model: SITRANS TF

Input: Resistance thermometers, Thermocouples, Resistance-type sensors, DC sources

Output: 4 to 20 mA, 4 to 20 mA with HART, Profibus PA or Foundation Fieldbus

• Local sensing of measured values over digital display
• Rugged two-chamber enclosure in die-cast aluminium or stainless steel
• Test terminals for direct read-out of the output signal without breaking the current loop

The SITRANS TF280 is a WirelessHART temperature transmitter that provides all measured process values as well as diagnostic information, parameters and functions via radio. The device is powered by an internal battery and designed for ultra low power consumption. Its compact and rugged design makes it specially suitable for direct mounting on tanks and pipes in remote parts of plants, and on moving or rotating equipment for process monitoring or asset management applications
