Description
The RHT-WM y RHT-DM transmitters include high-accuracy, highly stable sensors for measuring relative humidity and temperature. Measured values are converted into 4 to 20 mA output signals linearly related to the readings.
Being microprocessor-based, they can be fully configured using the TxConfig communication interface and Windows software. Humidity measurement and transmission can be set to Relative Humidity or Dew Point. The RHT-WM model is intended for wall mounting, and the RHT-DM model has an extended sensor sheath for duct or through-wall mounting.
– Power supply: 12 Vdc to 30 Vdc (4-20 mA model)
Output
4-20 mA or 20-4 mA current, 2-wire – loop powered
– Isolation between outputs:
Isolated 4-20 mA outputs
– Output load (RL):
4-20 mA model: RL (max. in ohms) = (Vcc – 12) / 0.02. Where: Vcc = supply voltage in volts
– Internal protection against reverse supply voltage polarity
Cable entry: PG7 cable gland
Operating limits
Electronic module: -10 to +65 °C, 0 to 95% RH
