Compressed-air thermometer hygrometer with Ethernet interface and relays, cable 1 meter
code: H3531PCompressed-air ambient humidity, temperature Ethernet sensor with two relay outputs. T+RH probe from hard anodized duralumin for compressed air up to 25 bars with cable. Humidex reading.
Sensor H3531P is designed for online monitoring of temperature, relative humidity of air without aggressive substances. Three binary inputs to detection of two-states signals are the advantage. Other devices are controlled by two relay outputs.
High precision capacitive polymer sensor ensures excellent long term calibration stability and ultimate accuracy. Measured values are also converted to other humidity interpretation: dew point temperature, absolute humidity, specific humidity, mixing ratio and specific enthalpy.
The device is supplied with T+RH probe with 1m cable. Cable lengths 2m or 4m available optionally.
Included in delivery:
- H3531P sensor
- Traceable calibration certificate
- Quick start manual
- Technical support at discussion forum
