Dwyer德威爾 RHP-2E/N44 RHP-2E/N40 露點溫濕度變送器

The SERIES RHP-E/N Wall Mount Humidity/Temperature/Dew Point Transmitter is the

most versatile room transmitter on the market. The stylish housing is well vented to

provide air flow across the sensor to improve measurement accuracy.

The humidity and the dew point are measured using a capacitive polymer sensor. The

humidity and dew point can have either a current or voltage output, while the optional

temperature output can be a current, voltage, RTD or thermistor. For models with

current or voltage for the temperature output, the temperature range is field selectable.
