Overview
This transmitter amplifies a signal from a RTD or linear resistance, and it turns the signal into a current which increases from 4 to 20 milliamperes as the temperature or input signal increases. This industry-standard 4-20mA signal travels thousands of feet over a pair of wires, ignoring electrical interference and bringing the temperature, accurately, into your computer or controller. Drawing power directly from the signal line, only 2 wires are needed for power and signal.
  • RTD or Ohm input
  • Accurate, Stable 4–20mA Output
  • PC and field-programmable
  • FM Approved Intrinsically Safe
Converts multiple inputs
Temperature measurement can be done with one of several RTD’s: 100 Ω, 1000 Ω platinum, 100 Ω Nickel and 1000 Ω Nickel. Because amplification and conversion of the input signal is performed within a few feet of the sensor, electrical interference in noisy environments is eliminated. The transmitter can be mounted at the field location in a standard DIN form B head or on a DIN rail inside a local box.
