- Indirect measuring method: Capacity determination in the high frequency stray field. This method uses the different dielectric constant (permittivity) of water and different materials (solids and liquids).
- Fully reproducible sensors: If the plant is subsequently extended with sensors or if sensors are replaced, no recalibration is necessary thanks to the built-in microprocessor.
- Waterproof and dustproof: The sensor is also suitable for the harshest environments thanks to its IP69K protection class.
- High sensitivity: The sensor surface is made of the high-temperature resistant, thermoplastic material PEEK.
- Process control and regulation: Thanks to extensive interfaces, the moisture measurement can be integrated into process control systems and controls.
- Cost saving: Time-consuming and costly laboratory analyses are no longer necessary or can be reduced.
- Limit values: Maximum or minimum limits can be set using the software. Light or sound signals can be triggered if required.
- Mean value calculator: The sensor passes on already averaged values to the FMS evaluation and transfer module.
- SIP & CIP: Cleaning in Place (CIP) und Sterilazation in Place (SIP)
- GEA VARINLINE Type-N Process connection, so you pretty flexible
- EHEDG: Hygenic food equipment certified according to the EHEDG guidelines
