Product Specification

Measuring trace humidity in gases

The dew point sensor NP330-G for trace moisture measurement in gases is a 4-20 mA transmitter for measuring absolute humidity in °C dew point or frost point (optional ppmW/ppmV). The measuring range of the sensor covers both, high humidity and trace humidity. The standard measuring range is -80°C FP to +20°C DP (other measuring ranges on request).

The integrated RS232 interface is used for data output and configuration of the sensor. The switching output of the sensor is also programmed via this access.

The high media compatibility creates a wide field of application possibilities as an online measuring device for various gases and gas mixtures. The sensor is used in industrial measurement technology for control, monitoring and quality assurance of air and gas conditioning.

Due to its wide measuring range, the sensor is used for monitoring and controlling refrigeration and adsorption dryers. The NP330-G ensures the quality of air drying systems in production processes and saves energy costs during drying.
