(T)FM80 OEM - duct version
OEM duct version with Polyga® measuring element
Features
- Accuracy: ±2.5 % RH
- very high accuracy in high humidity
- washable measurement element
- with the robust Polyga® humidity measuring element
- Long-term stability
- high-grade steel sensor material
- with resistance output
Typs:
FM80 – Humiditymodule
TFM80 – Humidity-Temperature-Module
TFM80 Module for integration in a wide range of customer-specific standard products.
With resistance output, the module does not require its own power supply.
Universal POLYGA® transmitters demonstrate excellent measuring properties and accuracy in high humidity. They can be adjusted and cleaned in water. Their outstanding durability, reliability and robustness make them the classic choice for applications with extended high humidity.
Remarkably straightforward and durable design
The Polyga® measuring element is a unique hygroscopic fibre that changes its length depending on the humidity. The changes in the length are converted into electrical resistance values that can either be directly measured (passive transmitters) or converted further into standard analogue output signals (active FG80 transmitters).
Waterresistent and maintenance-free
It has unparalleled long-term stability and is 100 % waterproof, which makes it ideal for use in high humidity. In pure ambient air the measurement element is maintenance-free.
