Duct Mounted Humidity Transmitter (0 to 100% RH)

Description

The 2232-150 Duct Mounted Relative Humidity Transmitter is
designed to measure relative humidity in an air duct and to
transmit a 3 to 15 psig 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. The pressure versus relative humidity curve is
shown in Figure 1.
The 2232-150 is a one-pipe, force-balance transmitter which
utilizes an external restrictor in a supply line. It incorporates a
highly sensitive hygroscopic nylon ribbon element and a ball
valve for pneumatic feedback which ensures accuracy
stability over the entire operating range. All internal parts are
corrosion resistant and there is an internal filter to maintain
cleanliness of operating parts. These features, along with
simplified design and small movement of operating parts,
provides an instrument with a long, maintenance-free life.
