2 Wires Humidity Transmitter – Lutron TR-RH2W

Features

  • Range : 10 %RH to 95 %RH.
  • Output : 4 to 20 mA DC.
    • 5.6 mA = 10 %RH, 12 mA = 50 %RH
    • 16 mA = 75 %RH, 19 mA = 95 %RH
  • 2 wires, both for signal and power supply.
  • Precision capacitance type humidity sensor.
  • External zero and span adjustment.
  • Allow high cable load resistance, transmitter can install far away from the controller/incator.
  • Protection for the reverse wires connecting.
  • TR-RH2W can cooperate the “4-20 mA Controller/Alarm/Indicator” CT-2012, then become a humidity controller and the indicating system. The user can control and monitor the humidity value from far away.
