SKU CH-WE0H-WETE4

Measures vacuum to 30 and pressure to 60 psi with ±0.5 % accuracy in a liquid-filled IP66 aluminium case

  • TypeElectronic
  • +/- 0.5% accuracy ensures precise vacuum and pressure readings
  • 4 1/2 in dial provides clear visibility in industrial settings
  • IP66 and NEMA 4X ratings protect against dust and water ingress
  • 1/2 in NPT male connection fits standard process piping
  • Liquid-filled case delivers vibration resistance for stable operation

Compound Gauge 30 to 0 to 60 psi

The Ashcroft 451379 process compound gauge measures vacuum and pressure from 30 inches Hg vacuum through 0 to 60 psi. A 4 1/2 inch white dial with glass lens sits in a black aluminum case rated IP66 and NEMA 4X for dust and water ingress protection. Accuracy is +/- 0.5 percent of span.

1/2 in NPT male bottom connection

The gauge mounts via a 1/2 inch NPT male process connection located at the bottom of the case. The unit is field fillable for liquid damping, though it ships without dampening fluid installed. Vibration resistance is provided by the liquid-filled design when filled.

Suits process monitoring needing vacuum and pressure

This gauge suits technicians and plant operators who need a single instrument for compound vacuum and pressure readings in harsh environments. It does not suit applications requiring electrical output signals or digital display integration. Buyers needing panel-mount or back-connection configurations should look at other models.

Questions about this item

Will the liquid fill need to be topped up or replaced over time?

The gauge is field-fillable, so the liquid dampening can be replenished or changed during routine maintenance without removing the instrument from service.

At what pressure does the +/- 0.5 percent accuracy limit apply across the 30 to 0 to 60 psi range?

The stated accuracy of +/- 0.5 percent covers the full span from 30 inHg vacuum through 60 psi pressure.

How hot does the aluminum case get and what is the power draw when the gauge runs continuously?

As a purely mechanical process gauge it draws no electrical power, and the aluminum case remains at ambient process temperature.
