L20-70 D- Polyester housing
Description:
- The Lidec type L20-70D, is specially designed for water ingress detection and offers a dependable solution for detecting the presence of liquids within dry cargos. The Lidec L20-70D is based on the propagation of a surface wave. This design does not include any moving part. The reliability of the device is ensured by a built-in function which monitors electronic or transducer failures.
- The polyester housing is designed to be installed in areas protected against adverse weather conditions.
The Lidec L20-70D does not require any calibration as it is not influenced by the surrounding cargo (e.g. coal,
cement, or any powdery substance).
