Dew Point

The Dew Point Sensor NP330- G

The Dew Point Sensor NP330-GThe Dew Point Sensor NP330- G  is a 4-20mA transmitter to measure absolute moisture in °C dew point (°C dp) in gases.

Due to a special manufacturing process it has a high media compatibility for use as online unit for the most diverse gases and gas mixtures for control, monitoring and quality assurance in gas treatment. Due to its wide measuring range the sensor is used for monitoring and control of freeze dryers and adsorption dryers.

The use of the NP330-G ensures the quality of air dryers in production processes and saves energy during drying.

Dew point switch  typ  NP 400

Dew point switch typ NP 400The dew point switch  typ  NP 400 is designed according to the same principle as the sensor above. However, as a low cost unit, it is especially intended to monitor  moisture in gases.

This is achieved by an electronic unit integrated in the sensor head and contains two adjustable outputs. A preset fixed switch point is triggered when the moisture is exceeded or falls short of it.
