H7012A,B
ROOM HUMIDITY SENSOR/ COMBINED ROOM HUMIDITY/TEMPERATURE SENSOR
PRODUCT DATA
GENERAL
The H7012A Room Humidity Sensor is a capacitance type relative humidity sensor for wall mounting.
The H7012B Combined Room Humidity/Temperature Sensor incorporates a capacitance type relative humidity sensor with a Pt 1000, BALCO 500 or 20kΩ NTC temperature sensor in one housing.
These sensors are used for control, indication and alarm monitoring in room air conditioning installations.
