Dew Point Sensor for OEM Application
The newly developed FA 505 is designed for OEM applications in desiccant and refrigeration dryers for long term stable dew point monitoring in industrial applications. Through our new sensor technology paired with a compact casing, FA 505 can be easy fit into dryers or other equipment which required long term dew point monitoring. This allows applications in smaller dryers and point of use dryers using a more energy efficient dew point control.
With a digital RS 485 interface, all values like e.g. dew point, temperature, absolute humidity... which are measured and calculated by the dew point sensor can be retrieved via the Modbus protocol. The sensor included sinter cap protects the sensor tip from dust and other particles, this ensures a stable measurement and low maintenance.
