The Barksdale UPA2 (0431-352) is an electronic pressure transducer used within marine control systems, where it converts a measured pressure into an analogue signal for monitoring and automation equipment. Its input range is 0-9.5 m H2O, and it delivers a 4-20 mA output over a two-wire connection from a 9-32 V DC supply. The configuration code 761-9500-K-1-2-1-K-4-3-006-000 identifies this specific build, and the cable assignment is marked white for UB+, brown for UB- and yellow-green for the case. This unit is offered in Used condition.
