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.
