The hygro module HM120 is a humidity-dependent switch that can be fitted in equipment such as hygrostats, humidifiers, dehumidifiers, ventilating fans, driers and many more. The module represents an on-off controller with changeover contact. The switch connection is via a connecting terminal, but can also be supplied ready-made with cable connections. Protection of the module is of the IP00 type. Remarkably straightforward and durable design Our Humidistats feature a simple and robust design. The Polyga® measuring element is a unique hygroscopic fibre that changes its length depending on the humidity. The changes in length of the POLYGA® fibres are transferred via a lever system to a microswitch, resulting in an on/off controller that needs no auxiliary power supply. 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.
