The RHT-WM y RHT-DM 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. Optionally, 0 to 10 Vdc voltage outputs are available.
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) or 18 to 30 Vdc (0-10 V model)
Output
4-20 mA or 20-4 mA current, 2-wire – loop powered
0-10 Vdc voltage (optional)
– Isolation between outputs:
Isolated 4-20 mA outputs
Non-isolated 0-10 V outputs
– Output load (RL):
4-20 mA model: RL (max. in ohms) = (Vcc – 12) / 0.02. Where: Vcc = supply voltage in volts
0-10 Vdc model: minimum 10 kOhms
– Internal protection against reverse supply voltage polarity
