The GC30 and GC31 digital pressure sensors from Ashcroft are said to pack substantial utility into a tiny IP40-rated enclosure.

Measuring just 1.2 x 1.2in and equipped with a 1-5VDC analogue output, a 3.5-digit LED display and dual-programmable switch contacts, the GC30 and GC31 pressure sensors perform the functions of a transducer, a digital indicator and a pressure switch.

Designed to monitor higher pressures in both gaseous and liquid media, the GC31 is offered in ranges from vacuum through 0/1,500psi.

A choice of a back or bottom 1/4 NPT pressure inlet allows the GC31 to be easily adapted to any installation requirement.

A panel-mounting bracket is provided with each GC30 and back-connected GC31.

Other standard features include minimum/maximum recall and adjustable analogue scaling along with RoHS and CE compliance.

Electrical connections are made through an integral 6ft (1.8m) five-conductor cable.

The GC30 measures low differential pressures from 0/0.25 through 0/25 H2O and similar bidirectional ranges.

Clean, dry gases are introduced through two back-mounted 4mm hose barbs.

Ashcroft Instruments

Over 150 years ago, Edward Ashcroft saw the need for safer, more sophisticated pressure and temperature instruments for use in the emerging steam industry. In response, he introduced a then-revolutionary new Bourdon tube pressure gauge. The rest is history.

Times continue to change and so do the needs of industry. Products manufactured by Ashcroft Inc. have become the benchmark in pressure and temperature measurement and include gauges, thermometers, switches, transducers, transmitters, instrument isolators and diaphragm seals and control and calibration equipment.

Specified around the world for the most demanding requirements, these instruments are widely recognized under the brand names Ashcroft, Heise, Willy, and Weksler. And you can find them in wastewater treatment facilities, biotech and pharmaceutical labs, medical applications, semiconductor facilities, refineries, power generation plants, food processing plants, pulp and paper mills, chemical manufacturing plants and the host of support companies that serve these industries.

Our team consists of experts ready to help resolve even the most difficult applications and technical issues. If you require broader specifications than our standard product line offers, our engineers, technical staff and product marketing specialists can work with you to custom fit the right product to the job. Our customer service representatives are highly trained to answer product application questions, offer competitive product cross-references and work closely with you to help meet your goals.

We maintain an extensive network of field and in-house sales personnel, local representatives and distributors to ensure you receive quick product delivery and service. Along with our “partner” representatives we offer product training and education, facility surveys, calibration services, seal assembly and answers to your application questions.  

Safety is a critical issue, and our instrument audit can improve the safety or your plant. Industry surveys indicate that 20% to 30% of customers’ instruments are misapplied and fail prematurely due to pulsation and vibration, allowing the process media or liquid fill to escape and cause environmental damage or even harm those nearby. Experts from Ashcroft Inc. can help identify areas of concern before they become problems. This important service will help prevent accidents, avoid misapplications and save money and time.  

As the leader in technology and innovation we design new products based on current and emerging market requirements as well as individual customer’s requirements. As the industry leader our “firsts” lead the way with breakthrough new product features and value added benefits for the customer. With our 2005 acquisition by (our longtime sensor partner) Nagano Keiki Company of Japan we now have access to additional engineering expertise and superior, exclusive sensor technology.
