Humidity and Temperature Transmitter
Microprocessor based humidity and temperature transmitters
The RHT-WM and RHT-DM transmitter series incorporate the best high accuracy and great stability relative humidity
and temperature sensors. They convert the measured values into linear 4 to 20 mA signals and optional 0 to 10 Vdc output
can also be offered under request.
The microprocessor based circuit enables full configuration of output range when used with the TxConfig PC interface and
the Windows® based software.
The humidity signal can be configured to either relative humidity or dew point output.
The RHT-WM model is dedicated to wall mounted applications and the RHT-DM version is suitable for duct and through-the-wall
applications.
- Power: from 12 Vdc to 30 Vdc (model 4-20 mA) or 18 to 30 Vdc (model 0-10 V)
- Output:
Two-wire loop powered 4-20 mA or 20-4 mA
Voltage output: 0-10 Vdc (optional)
- Isolation between outputs:
Isolated 4-20 mA outputs
Non-isolated 0-10 Vdc outputs
- Output load (RL):
Model 4-20 mA: RL (max. in Ohms) = (Vdc 12) / 0.02
- where: Vdc=power voltage in Volts
Model 0-10Vdc: 10 Kohms Minimum
- Internal protection against reversed voltage wire polarity
- Cable input: PG7 cable gland
- Operational Limits:
Sensor and Probe (RHT-DM)
Electronic Module: -10 to +65°C, 0 to 95%RH
