Order # TT-DR-R-100, Temperature Transducers

Base Price $176.00

  • 2 wire 4...20mA connection
  • Wide operating range
  • Low price
  • 0.5% accuracy

    The TT-R-100 is used to convert a platinum RTD temperature sensor to a 4-20 mA signal to interface with your energy management panel. The output is proportional over a selected span.
    The resistance change of the RTD passes through a bridge to the amplifier and is converted to a proportional d.c. current in the output stage. The output current is controlled through a feedback circuit and thereby becomes independent of load. A diode protects against reverse polarity. This technology is field proven and has been capable of withstanding rigorous environmental chamber testing while retaining linearity without damage.
    This technique produces a very reliable system with good accuracy at an excellent price.
