American Sensor Technologies' AST5400 Differential Pressure Transmitter
AST5400 differential pressure transmitter is 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.
