SITRANS TF Field Indicator for 4-20 mA Signals

Brand: Siemens AG
Does not ship to Virginia, United States
SITRANS TF is an IP67 field transmitter for heavy industrial use.

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.
Features
  • Flexible use - Local sensing of measured values over digital display; version without transmitter
  • Rugged two-chamber enclosure in die-cast aluminum or stainless steel
  • Easy handling - Test terminals for direct read-out of the output signal without breaking the current loop
  • Unobstructed operation – remote mounted sensor prevents transmitter from heating up, immune against vibrations and oscillations thanks to long neck tubes and protection pipes
