The PX760 is an industrial-grade,
microprocessor-based differential
pressure transmitter with 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.
Units can also be configured in the
field for a linear or square root
output for flow applications.
