  • 40 to 257 °F operating span handles extreme environments

Ashcroft G2 0-100 psi Transducer

The Ashcroft G2 is a pressure transducer built for industrial monitoring tasks. It converts a 0 to 100 psi range into a standard 4 to 20mA DC current loop signal. The unit carries a NEMA 4X enclosure rating and an IP67 ingress protection rating. It is suited for engineers and technicians needing reliable process pressure measurement.

Check power supply and process connection

Verify that the control system provides a DC supply between 9 and 36 volts. Confirm the process port accepts a male 1/8 inch NPT thread for direct mounting. Ensure the two-wire loop wiring matches the cable and wire leads provided. The transmitter operates accurately from -40 to 257 degrees Fahrenheit.

Thermals noise and power in normal use

The housing is moulded from nylon and rated for continuous operation up to 257 degrees Fahrenheit. As a passive two-wire loop device it draws its operating current directly from the 4 to 20mA signal circuit. No internal fan or active cooling is present so acoustic noise is negligible. Power consumption scales with the loop current.

Questions about this item

What comes with the transducer and what must I source separately?

The unit has 1/8 in male NPT threads and cable wire leads for a 2-wire 4 to 20mA loop powered by 9 to 36V DC. You supply the DC power source, any mating cable or connector, and thread sealant for the NPT port.

How do I choose between the available pressure ranges for this G2 series?

This specific transducer is fixed at a 0 to 100 psi range with +/- 0.50 percent full scale accuracy. If your system pressure exceeds 100 psi or requires a different span, you need a different G2 model with the appropriate range.

What does the +/- 0.50 percent full scale accuracy mean when the sensor is installed?

At the 100 psi upper limit the reading can deviate by up to 0.5 psi. The same absolute tolerance applies across the entire 0 to 100 psi span, so at 50 psi the error is still within +/- 0.5 psi.
