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 RANGE:
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)
