Supported Applications
The Omega PGM Series consists of stainless steel industrial pressure gauges designed for corrosive processing environments. The series is specified for use in chemical, petrochemical refining, power generation, marine, food, and pharmaceutical applications.
Operating Conditions & Performance
Performance specifications vary by dial size. Accuracy is ±1.6% of span for 63 mm gauges and ±1% of span (per DIN 16 005) for 100 mm gauges. The series supports a working pressure up to 75% of full scale with overrange protection rated at 130% of full scale.
Operating limits are defined as follows:
- Ambient temperature: -40 to 60°C (-40 to 140°F)
- Process temperature: -20 to 80°C (-4 to 176°F)
The gauges feature a NEMA 4 (IP65) degree of protection. Wetted materials include a 316 SS element and 316 SS pressure connection.
Configuration Options
The PGM Series is available in two dial sizes: 63 mm (2½") and 100 mm (4"). Each size offers distinct mounting configurations, window materials, and blowout protection arrangements as documented below:
- Mounting Options: Lower mount or flange mount fittings are available for both dial sizes.
- Process Connections: ¼ MNPT on 63 mm (2.5") models; ½ MNPT on 100 mm (4") models.
- Dial and Window: White aluminum dials with black lettering are standard. The window is Polycarbonate for 63 mm gauges and Laminated safety glass for 100 mm gauges.
- Blowout Protection: Top-mounted rubber disc on 63 mm (2.5") models; Back-mounted rubber disc on 100 mm (4") models.
The series is liquid-fillable in the field to provide resistance against vibration and pulsation. Measurement ranges span from vacuum applications up to high-pressure limits, including:
- Vacuum/Compound: Ranges such as 30 inHg vac to 15 psi (-1 to 1 bar) through 30 inHg vac to 150 psi (-1 to 10 bar).
- Pressure Only: Ranging from 0 to 15 psi (0 to 1 bar) up to 0 to 11600 psi (0 to 800 bar).
Key Product Differences
Model numbers follow the format PGM-DIAL SIZEFITTING-RANGE CODE. The dial size is indicated by "63" or "100", and the fitting type is denoted by "L" for lower mount or "B" for back (flange) mount. Examples include PGM-63B-15PSI/1BAR and PGM-100L-15PSI/1BAR.
Key distinctions between the two primary sizes are:
- Dial Size 63 mm (2½"): Features a Polycarbonate window, top-mounted rubber disc blowout protection, and ±1.6% of span accuracy.
- Dial Size 100 mm (4"): Features Laminated safety glass windows, back-mounted rubber disc blowout protection, and ±1% of span accuracy per DIN 16 005.

Great Function and reliablity
I use this gauge on a portable air manifold system. Holds up well to travel and is reliable.

Not the quality I was expecting.
The guage bounces around even with the correct oil added.

Not great not terrible.
I saw the pointer has a little screw on it to adjust, but the glass cannot be removed so the gauge cannot be zeroed.

2 1/2" PGM Vacuum Gauge
Gauge delivered on time. On arrival our calibration staff checked the gauge and found that it couldn't be zeroed. Contacted customer service and was told the gauge could not be returned because it had been used. Understood that it was a cheaper gauge could not be calibrated. Was hoping that accuracy could be verified but it failed.

What is the weight of one of these gauges? I am looking specifically at PGM-100B-6000PSI and PGM-100B-40Bar
Thank you for your inquiry. These weigh less than 5 lbs.

Does this gauge (and other gauges you sell) come with a calibration certificate? If not, can I purchase this separately?
Gene, these are low cost OEM gauges, these will not come with calibration, and we do not have the ability to calibrate them.

How do you calibrate zero? My gauge came in and it as well below zero.
The zero offset may caused buy an imbalance between the internal pressure inside the gauge and the outside pressure. You can try "burping" the gauge by momentarily removing the rubber plug on the top of the gauge. There is no mechanical adjustment procedure for these gauges

Hi, I have 12 of these gauges and would like to fill them with oil. Do you have oil that we can buy to fill them with? How much would I need to complete this job?
We do not sell the fill oils for the gauges. You can use glycerin, silicone oil or mineral oil to fill them. All should be fairly easy to locate. You should leave a small air space of approximately a 1/4 inch from the top of gauge when you fill them
