Duct Relative Humidity Transmitter

Model Chart

Specifications

Accessories

The Relative Humidity Transmitter is designed to

measure relative humidity in an air duct and to

transmit a 3 to 15 psig pneumatic signal over its 0

to 100% R.H. span to remote controlling, indicating,

and alarm devices such as receiver-controllers,

receiver gauges, and sensitive pressure switches.

Features:

• Widest possible (0 to 100%) relative humidity range for 3 to

15 psig (20.7 to 103.4 kPa) output.

• Shielded, highly sensitive, temperature-compensated nylon

sensing element, designed for duct insertion.

• Force-balance pneumatic feedback for stable, repeatable

operation.
