|Some Common Pressure Gauge Types|
The high reliability of the OMEGA® Commercial Gauge line is chiefly attributed to the unique OMEGA® Spring Suspended Movement. The entire movement is suspended between two springs, the Bourdon tube above and the link below. Wearing parts have been reduced to a minimum. Furthermore, these movement parts are ultrasonically cleaned and lubricated with silicone oil to ensure long cycle life. The OMEGA® Spring Suspended Movement is largely resistant to the effects of shock, pulsation, and vibration. The result of this is longer gauge life. The numerous applications for OMEGA® Commercial Gauges include installation on pumps, portable compressors, industrial machinery, hydraulic and pneumatic systems, instrumentation, and pressurized vessels. For the user, this means greater resistance to mechanical shock and vibration. This increased resistance to the effects of rough usage contributes to longer gauge life.
||Liquid Fillable Utility Gauges|
OMEGA’s PGUF series liquid fillable utility gauges are designed for a wide range of applications on pumps, compressors, hydraulic systems, machine tools and petrochemical processing equipment. For high shock and vibration applications the PGUF can be liquid filled in the field to dampen the gauge pointer movement. The PGUF Series liquid filled gauges come in ranges of (PSI/BAR) 0-30/2, 60/4, 100/7, 160/11, 300/20, 600/40 and 1000/70 (63 mm (21.2") gauge is also available in 2000/140 and 3000/200). Rated accuracy is ± 2.5% of span. Gauges feature a corrosion resistant 304 stainless steel case and ring, and a durable polycarbonate window. Phosphor bronze bourdon tubes with brass movement, socket and NPT connections are standard. PGUF gauges are available in 38 mm (11.2"), 50 mm (2") and 63 mm (21.2") designs with center back or lower mount NPT connections.
||General Service Gauges|
Sustained accuracy and excellent readability are important user features of the OMEGA® General Service Gauge line. Meeting the requirements of many industrial applications, General Service Gauges can be used on steam boilers or other pressurized vessels; on pumps and compressors; on many types of industrial machinery; in the chemical, petrochemical and allied process industries; in power plants; in pulp and paper mills. The pressure gauge actuation system in the OMEGA® General Service Gauge line is the standard 316 SS Bourdon tube system, which is engineered to precise tolerances for consistent repeatability and response to pressure fluctuations. Warning: All gauge components should be chosen with an eye to the media and ambient operating conditions to which they will be exposed, to prevent misapplication. Improper application can be detrimental to the gauge, cause failure, and possible personal injury or property damage.
||Stainless Steel Industrial Pressure Gauges|
OMEGA’s PGM series gauges are suitable for corrosive environments in chemical, petro-chemical, refining, power, marine and food and pharmaceutical processing applications. The PGM series comes in a 63 mm (21.2") or 100 mm (4") case, features all stainless steel construction and is environmentally protected to IP65. The PGM series can also be liquid filled in the field. Liquid filled pressure gauges provide users with a number of advantages in certain applications. They are ideally suited for uses on equipment where excessive vibration and pulsation are encountered such as pumps, compressors and machine tools etc. The liquid fill minimizes the effect of these severe environments, protects the gauge internals and provides continuous lubrication in the mechanism, all adding up to extended service life. Liquid filling provides greater protection of the gauge internals from corrosive atmospheres. Gauges can be filled with a variety of fluids including glycerin, mineral oil and silicone oil.
||Industrial Process Gauges|
These gauges are a very popular style for the factory floor. Thousands are installed world wide to monitor process pressures. Available in vacuum, compound and ranges up to 20,000 psi (1380 bar). A hermetic seal provides greater protection and efficiency.
||Type T: High Accuracy and Monel Wetted|
Highly accurate gauges designed for use in instrument shops, plants of all types, and laboratories throughout industry. They provide sustained accuracy to 0.25% full scale for most models. Performance, reliability and precision measurement are coupled with consistent accuracy in meeting the demanding service needs of numerous test gauge applications. These gauges are often used as master reference gauges, in test stand measurements, for production inspection, and for verifying the accuracy of general service gauges. They have a stainless steel mirror ring for pointer reflection to prevent parallax error. This mirror surface reflects the pointer in any position and allows the gauge to be read with great accuracy.
||Differential Pressure Gauges|
Differential pressure gauges are rugged industrial gauges which indicate the difference between two input connections. Differential ranges provide the maximum resolution for applications where one input is always at a higher pressure than the other. In cases where one input can be higher or lower than the other, a bi-directional differential range should be used. The OMEGA PGD Series is constructed with two independent Bourdon tubes. The opposing Bourdon tubes are linked to a single pinion gear which rotates a pointer for direct pressure readings. By using two independent Bourdon tubes, the gauge can handle liquids or gases on either or both ports.
