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. 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)
Two-wire loop powered 4-20 mA or 20-4 mA
Isolation between outputs
Isolated 4-20 mA outputs
- Output load (RL):
Model 4-20 mA: RL (max. in Ohms) = (Vdc – 12) / 0.02
where: Vdc=power voltage in Volts
- Internal protection against reversed voltage wire polarity
- Cable input: PG7 cable gland
- Operational Limits:
Electronic Module: -10 to +65°C, 0 to 95%RH
When the integrity of a product or package is threatened because of variations in humidity, the control and recording of this variable are essential to avoid losses. To maintain the quality standard in measurements, equipment with calibration certification is required. Thus, NOVUS offers relative humidity calibration for all its compatible products and for third-party instruments.
