The PX764 is an industrial-grade,
microprocessor-based pressure
transmitter with all 316 SS wetted
parts and a 2-wire 4 to 20 mA
output. The built-in 4-digit LCD
indicator can display the measured
pressure in bar, psi, or percent of
full scale. Parameters such as span,
zero, and damping can be adjusted
with the 2 pushbuttons on the digital
display.
