Differential pressure transmitter with two wire output
AST Sensors' AST5400 differential pressure transmitter is now available with a 4-20mA two wire output signal. The addition of the two wire output signal opens new markets and applications for the DP, which was traditionally used on off-road filtration systems and SCADA telemetry units requiring a voltage output signal. The 4-20mA output signal is more popular among test stand and OEM designs. It allows for long transmissions with greater noise immunity. The differential pressure transmitter is available with line pressures up to 5,000 PSI (350 bar) and is typically packaged with a measurement range of 1/10 to 1/15 it’s line pressure.
