    Model 231RS Differential Pressure Transducer

    Model 231RS is a multi-configurable wet to wet differential pressure transducer utilizing remote sensors. Model 231RS is ideal for monitoring pumps and load differential pressures in HVAC systems and processes where local indication is needed.

    Overview

    Model 231RS is a multi-configurable wet to wet differential pressure transducer utilizing remote sensors. Model 231RS is ideal for monitoring pumps and load differential pressures in HVAC systems and processes where local indication is needed. This design reduces labour and material costs versus traditional copper piping installations.

    The 231RS has a robust NEMA 4 enclosure with an LCD display and a hinged captive cover allowing for easy access to switches in order to adjust range and output. An optional display is available that allows users to view high, low and differential pressure readings on a simple rotating cycle. By connecting the high and low side transducers at the point of measurement instead of running copper piping back to the transducer, the labour and material costs are cut by one-third.

    All-inclusive field selectable design the 231RS has a multi-configurable design providing the user with field selectable ranges and outputs as well as push button or remote zero. This design gives the user total flexibility to make changes on the job site. Multiple connector options for added flexibility the 231RS offers remote sensors that connect to the unit via armoured jacket, cable or conduit fitting available in 10, 20, 30, 40 and 50 foot lengths. The visual indicator gives instant feedback providing performance validation to the user.
