SITRANS TF Field Transmitters are installed directly on the sensor thermowell or near the sensor, if the conditions like vibration or ambient temperature allow no installation of head transmitters. Available for intrinsic safety and explosion proof applications according to international standards. 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. This transmitter is used where other transmitters can't cope.
