Pressure Gauge

Pressure Gauge Industrial 1490

5″ and 3.5″ dial size.
Glass-filled polysulfone case material.
Beryllium copper diaphragm.
Brass socket.
Wetted materials of beryllium copper, brass, polysulfone and RTV silicone.

1490 low pressure diaphragm gauge is designed to measure pressure from 10 in.H2O to 15 psi, both positive and negative pressures. This pressure gauge uses a very sensitive diaphragm capsule to measure low pressure and vacuum.

The low pressure diaphragm gauge is specifically designed for use whenever the pressure medium is a gas that is not corrosive to beryllium copper, brass, polysulfone and RTV silicone.

Typical Applications are, but not limited to, vacuum pumps, gas leak detectors, air compressors, air filters, gas burners, gas measurement, vacuum ovens, suction regulators and respirators.

Pressure Gauge Industrial 1187

Available in 4.5″, 6″ and 8.5″ dial sizes.
Bellows-actuated mechanism.
Three bellows materials.
Nonadjustable, narrow-edge pointer for easy reading.
Phenolic (1188) or aluminum (1187, 1189) cases.
All-stainless steel movements.
1187 bellows pressure gauges are used for measuring low pressures from 10″ H2O to 10 psi pressure as well as vacuum and compound ranges.

Coupled with their sensitivity, these low pressure bellows gauges have a rugged design for process and industrial Applications.

Process Pressure Gauge 1259

5″ and 3.5″ dial size.
Glass-filled polysulfone case material.
Beryllium copper diaphragm.
Brass socket.
Wetted materials of beryllium copper, brass, polysulfone and RTV silicone.

Meeting ASME B40.1, 1259 process pressure gauge has been engineered to meet marketplace requirements. Many options which are not shown are available.

Process Pressure Gauge 1377

1377 Duragauge pressure gauge (4.5″, 6″, or 8.5″ dial sizes)
Standard stainless steel rotary geared movement with Teflon-coated gears and bearings

Process Pressure Gauge 2462

2462 Duragauge pressure gauge (6″ dial size)
Standard stainless steel rotary-geared movement with Teflon®-coated gears and bearings
Easily adjustable, self-locking micrometer pointer
100 standard psi and metric ranges, five standard systems.

This solid-front gauge is designed for greater readability by using a large 6″ dial and a durable 4.5″ system. Viewed from the front, it appears to be a 6″ gauge.

Its glass-filled polypropylene case is highly impact resistant and holds up well in most environments. This general-purpose gauge offers truly functional styling and economy.

The result is a process pressure gauge that will fit most Applications at a price that represents outstanding value.

Process Pressure Gauge 1279

1279 Duragauge pressure gauge (4.5″ dial size only)
Standard stainless steel rotary geared movement with Teflon®-coated gears and bearings
Easily adjustable, self-locking micrometer pointer
1100 standard psi and metric ranges, five standard systems
These Ashcroft pressure gauges are in stock for immediate delivery. FLW will not be beat on price, quality or service.
Pressure Gauges are readily available with chemical seals and capillaries of any length.

The solid-front Ashcroft phenolic case gauge is truly an industry first. Offered in 4.5″ size only, weather-proof, hermetically sealed or liquid-filled versions.

The weatherproof gauge is easily field converted to a hermetically sealed or liquid-filled gauge with a special kit. Molded threads at the front and rear of the case provide axial seals with the use of threaded rings.

The ring is glass-filled polypropylene. In the weather-proof version, the pressure relief back is polypropylene, fastened with stainless steel screws.

Process Pressure Gauge 1379

1379 Duragauge pressure gauge (4.5″, 6″, or 8.5″ dial sizes)
Standard stainless steel rotary-geared movement with Teflon®-coated gears and bearings
Easily adjustable, self-locking micrometer pointer
100 standard psi and metric ranges, five standard systems

This rugged, solid-front aluminum case pressure gauge is tops in its field. It is available as a weatherproof hermetically sealed or liquid-filled version in 4.5″ and 6″ sizes in pressures to 30,000 psi.

Like the Ashcroft 1279 process pressure gauge, it can be easily field converted from the weatherproof version to either the sealed or liquid-filled version using an optional kit.

Ranges 50,000, 80,000 and 100,000 psi are available in 6″ hermetically sealed and liquid-filled cases. All size cases are coated with black epoxy which will withstand most environmental conditions.

Pressure Gauge Industrial 1010

5″, 6″, 8.5″ and 12″ dial sizes.
Open-front case style, black epoxy-painted aluminum case.
Slip-fit steel ring, black epoxy-painted.
Non-adjustable pointer.
