Pressure transmitter for vacuum-to-30-psi systems

This Ashcroft G2 pressure transmitter measures from minus 15 psi up to 30 psi and outputs a 1 to 5 V DC signal. It suits process and outdoor power equipment that need a compact transducer with a DIN 43650 Form A electrical connector and a male 1/8 in NPT process connection.

Output range and accuracy define fit

The transducer delivers a linear 1 to 5 V DC output across the full vacuum-to-30-psi span with an accuracy of +/- 0.50 percent full scale. A three-wire design operates on a 9 to 36 V DC supply, so the single electrical specification that decides compatibility is the required output voltage range and supply window.

Rated for harsh environments

The housing carries a NEMA 4X rating and an IP65 ingress rating, sealing the electronics against wash-down and dust. It operates continuously from minus 40 degrees F to 257 degrees F, and the cable-gland wiring entry maintains the seal during normal use without adding audible noise or significant power draw.

Questions about this item

What does the -15 to 30 psi range mean when the transmitter is installed on a pressure washer?

The transmitter reads vacuum down to -15 psi and positive pressure up to 30 psi, so it covers both suction and discharge sides of the pump.

How does the DIN 43650 Form A connector limit the output signal in practice?

The three-wire DIN 43650 Form A plug carries the 1 to 5 V DC output and the 9 to 36 V DC supply, fixing the voltage interface to that pin layout.

What mounting hardware does the 1/8 in male NPT process connection require?

It threads directly into a 1/8 in female NPT port; no flange or adapter is needed beyond standard pipe sealant or tape.
