Humidity and Temperature Sensors Transmitters

Temperature and humidity sensors for industrial environments that require high accuracy, stable readings and a fast response. Easy to configure outputs for current or voltage signals. Available as wall or duct mounting with two insertion lengths. Ranges from -40 to 120°C for temperature and 0-100% for humidity

Temperature and Relative Humidity Sensors

Loop powered 4-20 mA or 20-4mA outputs.

Voltage outputs 0-10Vdc (optional).

Power supply: 12 to 30 Vdc (4-20 mA output) or 18 to 30 Vdc (0-10 V output).

Channel isolation: the 4-20 mA outputs are isolated from each other. The 0-10 V outputs share a common ground.

Reverse polarity protection.

Cable entrance: compress fitting PG7.

Operating limits:
Sensor probe (RHT-DM): -20 to 80 °C, 0 to 100 %RH.
Electronic circuit: -10 to +65 °C, 0 to 95 %RH.

RH channel:
Accuracy: ±1,5 %RH @ 25 °C, from 20 to 80 %RH.
Repeatability: ±1% RH.
Hysteresis: ±1% RH.

Span: any value between 0 and 100% RH or –40 to 100°C for dew point.

Temperature channel:
Accuracy: ±0,5 °C @ 25 °C. Maximum ±2 °C from -40 to 80 °C.
Repeatability: ±0.1°C.

Span: between -40 and 120°C.

The Relative Humidity and Temperature Transmitters RHT-WM and RHT-DM are microprocessor based instruments that incorporate high accurate and stable sensors whose information is converted to linear 4-20 mA or 0-10 Vdc.

Using the digital communication interface, the transmitter parameters can be configured to tailor a particular application.
The RHT-WM model is intended for wall mounting. The RHT-DM comes with a probe tip for duct mounting.
