231RS Series

REMOTE MOUNTED DIFFERENTIAL PRESSURE TRANSMITTER

The 231RS Series Multi-Range Differential Pressure Transmitter is ideal for monitoring pumps and load differential pressures in HVAC systems and processes where local indication is needed.Setra's 231RS Series with remote sensors reduces labor, materials, and time. The sensors are installed directly into the pipe and electrical connection is made between the remote sensors and the Model 231RS via cables or conduit. This reduces labor cost by one-third and the cost of copper to connect the pressure transducer to the pipe. Startup time is reduced since purging air out of the lines is not necessary.The Multi-Sense® Model 231 wet-to-wet differential pressure transducer's all inclusive design provides users with field accessible ranging, choice of output and field zeroing.
