Relative humidity sensor
FOS&S
The fibre optic humidity sensor HS-01 makes use of a humidity sensitive element that is connected to a FBG. The humidity element shows a very strong swelling effect when humidity reaches 80%. Due to the swelling, the FBG will be strained resulting into a wavelength shift of the FBG. The complete system is mounted within a ruggidised housing foreseen of a water ingress filter.
In order to compensate for temperature influences, a high resolution temperature probe is integrated within the housing.
The housing is made of stainless steel and is terminated with an optical connector using a plastic tubing. Tubing lengths and connector can be specified following the needs of every application.
The sensor also can be connectorised at both ends to make series configurations possible.
Features
The fibre optic humidity sensor HS-01 is an on/off sensor that detects water ingress or relative humidity above 80%. The sensor also can measure temperature with a resolution of 0,1°C and an accuracy of 1,0 °C respectively.
Applications
The humidity sensor HS-01 can be mounted on as well as embedded in all kind of structures for leakage detection of pipelines, dams, dikes,...
