Temperature and Humidity Transmitters

Temperature and Humidity Transmitters

This relative humidity and temperature transmitter complete with sensors continuously measures temperature and humidity and provides a 4-20mA output signal over the range of both sensors. The transmitter is housed in a sturdy Macrolon box rated to IP67. There are three styles of mounting. Wall mounted, duct mounted (using a compression fitting) or wall mounted with remote sensor. A dust filter is available as an option. A dual display indicator/on-off indicator/controller reference 715-115 is available to suit this humidity/temperature transmitter.
  • Probe dimensions:
    Wall mounted, 135mm long x 14mm diameter
    Duct mounted, 135mm long x 14mm diameter (mounting flange and gland required)
    Remote mounted, via 2 mtr leads to 135mm or 335mm long x 14mm dia. probe
  • Relative Humidity:
  • Measuring range: 5% to 98%
  • Accuracy: ±2% RH - 5 to 90% RH; ±2.5% RH - 90 to 98% RH

  • Response: (63% of full value) without filter 6 seconds, with filter 3 minutes
  • Measuring range: -20°C to +80ºC
  • Accuracy: ±0.2ºC, ±0.15% of reading
  • Output: 4 to 20mA configurable
  • Response: (63% of full value) without filter 6 seconds, with filter 2 minutes
  • Power supply required: 16V to 40V DC
  • Ambient operating temp: Sensor -20ºC to +80ºC, Electronics 0ºC to +60ºC
  • Junction box dimensions: 80 x 84 x 44mm (HxWxD)
