Ashcroft 2174 Vacuum Gauge Transmitter

The Ashcroft 2174 is a digital vacuum gauge with an integrated transmitter designed for pressure measurement from 0 to 100 psi. It features a 3 in nominal dial size and a stainless steel wetted construction with an IP65 rating for demanding environments.

Suits technicians needing 4-20mA output

This gauge suits technicians who require a 4 to 20mA DC output signal for integration with control systems and data loggers. It is not for operators who need a purely mechanical gauge without electronic signal transmission or external power requirements.

Accuracy decides the application

The single specification that determines suitability is the accuracy of +/- 0.25 percent of full scale. This precision level dictates whether the instrument meets the calibration standards required for your specific process control or testing application.

Questions about this item

Does the 1/4 in NPT male process connection on the Ashcroft 2174 require a specific adapter for my existing plumbing?

The gauge uses a 1/4 in NPT male bottom connection. You will need a matching female NPT fitting or an appropriate adapter to connect it to your system's piping.

Will the 4 to 20mA DC output from this transmitter work with my older panel meter that expects a 0 to 20mA signal?

The transmitter provides a 4 to 20mA DC output. A 0 to 20mA panel meter will read 4mA as a non-zero value, so you would need to adjust the meter's zero offset or use a signal converter for correct readings.

How can I verify the +/- 0.25 percent full scale accuracy of the Ashcroft 2174 after installation?

Apply a known reference pressure from a calibrated source across the 0 to 100 psi range. Compare the displayed reading and the 4 to 20mA output signal against the reference to confirm they fall within the stated tolerance.
