C7600A,C

Solid State Humidity Sensors

APPLICATION

The C7600A,C Solid State Humidity Sensors sense relative

humidity in air and are used with controllers that can process

a 4 to 20 mA signal (see Table 1).

FEATURES

• Sensor enclosed in rugged glass-fiber reinforced

plastic case.

• Compact size and lightweight construction for easy

mounting in duct or on wall.

• Cover vents allow air flow to humidity sensing element

inside.

• 4 to 20 mA output to relative air humidity.

• Can be used indoors or outdoors.

• The C7600A provides 4-20 mA output inversely

proportional to air relative humidity.

• The C7600C provides 4-20 mA output directly

proportional to air relative humidity.
