HART®

HART® or Highway Addressable Remote Transducer is a type of digital communications protocol for configuring and reading instrumentation via the 4 to 20mA current loop. HART® data is communicated via a low level AC digital signal which is superimposed on a 2 wire 4-20mA current loop signal and functions simultaneously without interfering with the measurement output signal.

• 30 to 300 psig natural gas HART 4-20mA pressure sensor for oil and gas use
• XMD Process Plant DP Cell Differential Pressure Transmitter
• LMK382 Low Range IP68 Waste Water Level Transmitter
• 500 psi absolute range HART enabled 4-20mA output diesel pressure sensor for pipeline leak testing use
