SENSING ELEMENT: hygroscopic polymer film with special treatment, guaranteeing a fast response, long lifetime and high stability
HOUSING: Wall mounting, with vents. IP30.
Housing must be placed in a naturally ventilated area to ensure a good humidity measurement and be protected against the risk of splashing water. Do not use in rooms with risk of condensation.
MOUNTING: wall mounting by two screws accessible after removing the cover. In standard this cabinet also provides a backside clip to snap on symmetrical DIN rail
ADJUSTMENT: by knob graduated in % relative humidity, from 20 to 80% on 235 ° angular.
CALIBRATION: at mid position at 42% RH and 22 ° C. Calibration tolerance at mid point: + / -5% relative humidity. Minimum and maximum positions have positive contact actuation
CONTACT STYLE :
SPDT, the NC opens when the relative humidity goes above the set-point (humidification applications), the NO contact closes when the relative humidity goes above the set-point (ventilation or dehumidification applications)
CONTACT MATERIAL :
ELECTRICAL CONNECTIONS: screw terminals
AMBIENT CONDITIONS :
Humidity: 5 to 95% without condensation
Ambient temperature: 5 to 40°C
OPTIONS: Customized housing or knob (MOQ Apply)
Gold plated contact
Rotation to increase set-point
