The gauge type IPT is a two-port device available in 1, 2, 5, 10 and 20 psig ranges. Instead of supplying a vacuum reference to one side of the silicon diaphragm, it is plumbed to an external reference, typically ambient pressure. Movement of the IPT gauge diaphragm is only characterized in one direction. For a gauge IPT to operate properly, the pressure at port P1 must always be greater than the pressure at port P2. The gauge IPT has a maximum total error band of ±0.10% full scale output over a temperature range of -40ºC to +85°C.
