Relative humidity and temperature transmitter (T)FG80

wall-mountresistance4-20 mA

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.
