Ashcroft GC51 150 psi Transducer

The Ashcroft GC51 is an electronic pressure transducer built for industrial monitoring up to 150 psi. It suits technicians and engineers who need a local digital readout combined with a standard 4 to 20 mA output signal. The IP66 and NEMA 4X rated enclosure withstands harsh wash-down environments. Its 17-4PH and 316 stainless steel wetted parts resist corrosion in demanding process applications.

Accuracy ±0.25% Full Scale

The single specification that decides fit is the accuracy of ±0.25 percent of full scale across the 0 to 150 psi range. This precision level determines whether the instrument meets your calibration and control-loop requirements. The two-wire 4 to 20 mA loop-powered design simplifies wiring over long cable runs. Process connection is a 1/4 inch female NPT located on the back for panel or pipe mounting.

Integrated LCD Display Included

The built-in LCD display shows live pressure readings directly in psi without a separate handheld meter. This reduces commissioning time and allows operators to verify process conditions at the point of measurement. A 1/2 inch FNPT conduit entry protects signal wiring from moisture and mechanical damage. No additional software or configuration tools are bundled with the unit.

Questions about this item

What does the 150 psi upper limit mean when the transducer is installed in a live system?

The sensor reads from 0 to 150 psi and outputs a 4 to 20 mA signal proportional to that range, so the controller sees 4 mA at zero pressure and 20 mA at full scale.

How does the 4 to 20 mA two-wire loop limit cable length and supply voltage in practice?

The loop drops voltage across the cable resistance; with a typical 24 V supply you can run several hundred metres of standard instrument cable before the transmitter falls below its minimum operating voltage.

What mounting clearance and thread engagement does the 1/4 in female back connection need?

The back-mounted 1/4 in female port threads onto a male NPT fitting; allow enough depth for full thread engagement and clearance for the 1/2 in FNPT conduit entry on the housing.
