Galltec + Mela Humidity Transmitter Controller Polyga Humidistat HG80
This is a Brand New Galltec + Mela Humidity Transmitter Controller Polyga Humidistat HG80
Description of the Humidistat
The humidity measuring element, produced by Galltec under the name Polyga®, consists of several synthetic fabric bands each with 90 individual fibres with a diameter of 3 µm. A special process gives the fibre hygroscopic properties. The measuring element absorbs and desorbs humidity. The swelling effect, which is predominantly in a lengthways direction, is carried via a suitable lever system to a microswitch with an extremely small switching path. The measuring element reacts quickly and precisely to the change in air humidity. By adjusting the setpoint value control knob, the lever system is engaged so that when the set air humidity is reached the microswitch is activated.
Application
The humidistat type HG80 is used as an on-off controller to control the relative air humidity in air ducts of air conditioning units and climatic cabinets, and to control air humidifying and dehumidifying. Other areas of use are storage of foodstuffs and luxury foods, cooling rooms for fruit and vegetables, greenhouses for gardening use, the textile industry, the paper and printing industry, film industry and hospitals.
