Intrinsically Safe Transducer 0-5 psi

The Ashcroft A4 series transducer measures pressure from 0 to 5 psi with a 4 to 20mA DC output. It is built for hazardous-area installations where intrinsic safety certification is required. The DIN 43650 Form A connector simplifies wiring in the field.

Accuracy and operating envelope

Accuracy is rated at +/- 0.50 percent of full scale across the range. The unit operates from -40 to 257 degrees Fahrenheit and accepts a 12 to 30V DC supply. NEMA 4X and IP65 ratings protect against wash-down and dust ingress.

1/2 inch NPT process connection

A male 1/2 inch NPT thread mounts directly into compatible process ports without adapters. The two-wire loop-powered design reduces cabling cost and panel space. Mating connector is included for immediate termination.

Questions about this item

Will the A4 transducer's 1/2 in male NPT process connection thread directly onto my existing pressure washer pump outlet?

The transducer has a 1/2 in male NPT process connection, so it will thread directly onto a matching female NPT port; verify your pump outlet uses the same thread standard before installing.

How can I confirm the transducer is operating correctly after wiring it to a 12 to 30V DC supply?

With power applied and zero pressure, the output should read 4 mA; at full-scale 5 psi it should read 20 mA, staying within the stated +/- 0.50 % accuracy across the range.

Does the box include the mating DIN 43650 Form A connector, or must I source it separately?

The specification lists wiring entry with mating connection, indicating the matching DIN 43650 Form A connector is supplied in the box.
