Ashcroft 302174SD02LXBLBK30# Digital Vacuum Gauge with Transmitter 0 to 30 psi

SKU CH-NHNZ-FQG5V

Digital vacuum gauge measuring 0 to 30 psi with ±0.25% accuracy, 4-20 mA output, IP65 rating and 1/4 in NPT bottom connection

  • TypeElectronic
  • +/-0.25% full-scale accuracy for precise vacuum readings
  • 4-20 mA DC output enables direct control-system integration
  • IP65 rating protects against dust and water jets
  • Stainless-steel wetted parts resist corrosion in harsh media
  • Eight selectable pressure units cover bar, psi, kPa and more

0-30 psi Digital Vacuum Gauge

This Ashcroft 2174 series gauge measures vacuum and pressure from 0 to 30 psi with ±0.25 % full-scale accuracy. The 3-inch digital display reads in ten selectable units including bar, kPa and in Hg. A 4-20 mA DC transmitter output allows direct integration with data loggers or PLCs. The IP65-rated stainless-steel case suits panel or field mounting.

Instrument technicians and HVAC installers

Technicians who need a single instrument for vacuum verification and low-pressure testing will find the wide unit selection and analogue output convenient. Users requiring measurement above 30 psi or a different process connection must select another model. Buyers needing a battery-powered standalone display without loop wiring should look elsewhere.

4-20 mA DC transmitter output

The gauge provides a two-wire 4-20 mA DC signal proportional to the 0-30 psi range for remote monitoring. A 1/4 inch male NPT bottom connection fits standard ports. Wetted parts are stainless steel for compatibility with common fluids and gases. Accuracy is stated as ±0.25 % of full scale across the operating range.

Questions about this item

How can I verify the gauge is reading correctly after installation?

Apply a known reference pressure within the 0 to 30 psi range and confirm the display shows a value within ±0.25% of full scale for the selected unit such as psi or kPa.

What components are included and what must I source separately?

The gauge with 1/4 in Male NPT bottom connection and integrated 4 to 20 mA DC transmitter are supplied; a compatible DC power supply for the loop and any required tubing or fittings are not included.

Which pressure range version should I select for my application?

Choose the 0 to 30 psi model when your working vacuum or pressure stays within that span; the Series 2174 design covers the full scale with the stated accuracy across all supported display units.
