RHT series transmitters incorporate highly accurate, stable sensors for measuring temperature, relative humidity and dew point. Measured values are converted into 4 to 20 mA output signals linearly related to their readings. They are fully configurable via the TxConfig communication interface and Windows® software.
The RHT-XS model is suitable for applications where the sensor module must be separated from the electronics module, but in an environment at the same pressure. Housing with remote probe, cable length 3 meters.
Humidity measurement :
- Measurement range: Configurable between 0 and 100% RH or -100 and 103 °C dew point
- Response time (1/et (63%)): 8 seconds @ 25 ºC (with air moving at 1 m/s)
Temperature measurement :
- Measurement range: Configurable between -40 and 120 °C
- Response time (1/and (63%)): up to 30 s (with air moving at 1 m/s)
- Power supply: 12 Vdc to 30 Vdc
- Outputs: 4-20 mA or 20-4 mA current, 2-wire type - loop powered
- Load on outputs (RL)
- RL (max. in Ohms) = (Vcc - 12) / 0.02 Where: Vcc= Supply voltage in Volts
- Output resolution OUT1: 0.006 mA
- OUT2 output resolution: 0.022 mA
- Isolation between outputs
- Isolated 4-20 mA outputs.
- Internal protection against reverse polarity of supply voltage
