Stainless steel cylindrical transducer with M12 connector and 1/4 NPT male fitting

Ashcroft

Ashcroft G2 Pressure Transducer -15 to 30 psi 4-20mA M12 NEMA 4X IP67

SKU CH-T8AV-0751D

Measures -15 to 30 psi with 4-20mA output, M12 connector, NEMA 4X and IP67 protection

  • TypeElectronic
  • Accurate readings with ±0.50 % full-scale precision
  • Wide range covers -15 to 30 psi in one unit
  • Rugged NEMA 4X and IP67 enclosure resists dust and water
  • 4-20 mA two-wire loop simplifies wiring and power
  • Operates reliably from -40 °F to 257 °F

Purpose and fit

The Ashcroft G2 pressure transducer measures from -15 psi to 30 psi and outputs a 4 to 20mA DC signal on a 4-pin M12 connector. It suits process and test engineers who need a 2-wire, loop-powered sensor with 1/4 in male NPT process threads for direct pipeline or vessel installation.

Thermals and power

The unit operates from -40 °F to 257 °F while drawing 9 to 36 V DC, so it tolerates wide ambient swings without active cooling. Its NEMA 4X and IP67 ratings mean the housing resists wash-down, corrosion and temporary immersion, keeping the electronics dry and quiet in harsh plant environments.

Deciding specification

The +/- 0.50 percent full-scale accuracy determines whether the transducer meets your calibration envelope. If your procedure demands tighter tolerance, this sensor will not satisfy the requirement.

Questions about this item

How do I wire the 4-pin M12 connector for the 4-20mA 2-wire loop?

Connect the supply positive to pin 1 and the signal return to pin 3; pins 2 and 4 stay unused. The loop draws 9 to 36V DC and the transmitter regulates 4 to 20mA proportional to -15 to 30 psi.

What ongoing checks does the G2 transducer need after installation?

Verify the 4-20mA output against a calibrated reference at 0 psi and full scale annually; inspect the 1/4 in NPT seal and M12 connector for corrosion, and confirm the NEMA 4X IP67 enclosure remains intact.

At what temperature does the transmitter hit its operating limit first during continuous service?

The upper limit is 257 Degrees F; sustained process or ambient heat above this value will exceed the specified range before the -40 Degrees F lower limit becomes relevant.
