The OMEGA PX157 transmitter
provides an accurate, reliable, and
economical means for monitoring
differential pressures in HVAC
automation, pneumatic systems,
and process control. The output
can be easily interfaced with chart
recorders, data loggers, and
computerized monitoring and
control systems. Modern, lowpressure chemical vapor
deposition methods provide
simple, stable molecular bonds
