Pressure Gauges

 

Pressure GaugesESP Gauges is a US manufacturer of industrial pressure gauges and we became affiliated with ESP during the summer of 2017.  They can provide a complete range of pressure gauges, which includes the very low cost commodity products to extremely precise industrial grade pressure gauges, differential pressure gauges and related accessories such as diaphragm seals and needle valves.

 

Most of our pressure gauges are available to ship from stock and are drop-shipped directly from the manufacturers warehouse in Georgia.  We can also accommodate requests to establish minimum inventory levels for OEM's with JIT delivery goals.

 

DIAL SIZE

Standard available dial sizes: 1”, 1½”, 2”, 2½”, 3½”, 4”, 4½”, 6”, or 8½”. Other dial sizes are available. Determine dial size by measuring across the diameter of the face.

 

CONNECTION LOCATION

Lower mount is the most common. Center back mount or lower back mount is also considered standard. Other locations can be supplied by special request.

 

CONNECTION SIZE

Typical sizes include ⅛”, ¼” and ½” NPT. Other sizes and types of connections are available upon request. Please call to verify if there are special requirements.

 

MOUNTING

Lower mount or back mount (without special mounting hardware). Panel mount - U-clamp. Panel mount - Front flange. Wall mount - Back flange.

 

MATERIAL OF WETTED PARTS

Refers to all parts in contact with process fluid. Please check corrosion guides for suitable materials. Most applications are compatible with copper alloy or bronze tube and socket. More severe applications may require 316 stainless steel. Most severe applications require Monel parts. If none of these materials are adequate for the application, a diaphragm seal will be required.

 

DRY OR LIQUID FILLED

Dry gauges are suitable for most applications. Glycerine filled gauges will be specified for applications with pulsation or vibration or for other reasons based on customer preference. Silicone filling may be required where process conditions do not allow the use of glycerin filling, such as temperature extremes or concerns regarding interaction with the process media. Other fluids are available, please
call for assistance.

 

CASE MATERIAL

Industry standard case materials for gauges include: black painted steel, chrome plated steel, aluminum, stainless steel, Phenolic and polypropylene.

 

RANGE

Specified in PSI for pressures from 0 up to 15,000 PSI or in inches of mercury vacuum for 0 to 30” Hg vacuum. Compound ranges have both pressure and vacuum. Other available scales: Metric (BAR, kPa, kg/cm2, mPa), Low pressure (inches of water column or millibar), Altitude (feet of water or meters of water), Force (tons on ram) and many others.

 

ACCURACY

Typically will be determined by size and type of gauge specified above. Accuracy grades are specified by ASME standards.

 

CERTIFICATION AND CLEANING

Conformance Certificate - States that gauge meets catalog and/or order specifications.

Certificate of Accuracy - Gauge is tested up scale and down scale with accuracy and percentage of error noted. Traceable to NIST.

Special Certification/Material Certification - By customer request, particular aspect of gauge certified to meet customer requirement.

Oxygen Cleaning - Gauge cleaned and bagged, suitable for oxygen service. Special Cleaning - By customer request, cleaned to a particular cleanliness level required by customer.

 

OTHER

Any other special process conditions to be aware of or any special requirements the customer may have, such as approvals for 3A, NACE, UL or others.
