The TPD-2500.. transmitters are dual-loop differential pressure gauges TPD-2500-… designed to measure inert gas pressure differences in HVAC applications.

They allow to measure two pressures or two independent pressure differences that can be transmitted separately in the form of 4..20mA or 0..10V signals selectable by internal jumpers.
