  • for on-off control of relative humidity
  • in air ducts, climatic cabinets, storage and cold rooms
  • for controlling, humidifying and de-humidifying the plant
  • for duct, wall and C-rail mounting

Description

Specially prepared plastic fibres are used as the sensing element in hygrostats. The hygroscopic properties of the fibres produce a proportional change in the length of the sensing element with changes in relative humidity.
The length change is transmitted through a precision mechanism to a microswitch with an extremely small switching displacement. Movement of the setting knob shifts the mechanism so that the microswith is operated when the relative humidity setting is reached.
The duct version is also available with two changeover contacts.
The contact spacing is adjustable within the range 3-18 % rH.
