MAIN FEATURES
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 :

Gold plated silver: recommended when storage at high humidity conditions may occur, or when the product is used in low voltage application (electronic control boards)

Silver: recommended for standard resistive load application or low inductive loads

ELECTRICAL CONNECTIONS: screw terminals

AMBIENT CONDITIONS :

   Humidity: 5 to 95% without condensation

   Ambient temperature: 5 to 40°C

RATING:

• UL and CSA: 6A resistive, 20A LRA, FLA 3.7A, 240V

• EC: 6A resistive, (3.7A inductive) 250V

OPTIONS: Customized housing or knob (MOQ Apply)
