Preciman
FranceMeasurement & DetectionPreciman manufactures pressure and vacuum measurement instruments for industrial process control and equipment monitoring. The product line centers on mechanical pressure gauges and manometers available in multiple dial sizes (50–100 mm), pressure ranges (vacuum to 250 bar), and construction materials (glycerin-damped stainless steel, carbon steel, all-stainless). Gauges are supplied with axial or vertical connection orientations and standard thread ports (G1/4, G1/2) to integrate into boiler...

Frequently asked questions
Common questions about Preciman from 3G Electric.
What is the difference between a Preciman glycerin gauge and a dry pressure gauge?
Glycerin-filled gauges contain silicone oil that dampens needle oscillation, reducing vibration noise and extending component life in pulsating systems such as pump discharge or combustion-gas lines. Dry gauges have no fluid and respond more rapidly to pressure spikes. Preciman supplies both types; glycerin models are typical in boiler and steam applications, while dry gauges suit static or slowly varying pressures.
What pressure ranges does Preciman offer for its D63 and D100 gauges?
Preciman D63 gauges are available from vacuum (−1 to 0 bar) through 0–250 bar full scale. D100 models typically span 0–2.5 bar, 0–40 bar, and vacuum ranges. Both sizes accept G1/4 and G1/2 female thread connections. We carry SKUs across this range; consult the product selector for your exact process pressure.
Are Preciman stainless-steel gauges suitable for wet-steam or corrosive environments?
Preciman all-stainless constructions (case, internals, and bourdon tube) resist corrosion from steam condensate, chloride exposure, and acidic vapor. Axial and vertical orientations are available. Standard stainless gauges are rated for typical industrial steam and boiler duty; verify material compatibility with your plant's water chemistry or hazardous-gas atmosphere if required.
What thread sizes do Preciman gauges use, and are adapters available?
Standard Preciman gauges ship with G1/4 or G1/2 female BSP ports. We stock thread adapters and manifold fittings to mate with NPT, BSPP, or metric threads. Confirm your plant's port type before ordering; custom-order leads apply to non-standard connections.
How do I select the correct dial size and pressure range for my boiler or pump application?
Size the gauge so operating pressure sits in the middle third of the dial (e.g., 0–10 bar gauge for a 3–4 bar operating line). Preciman D50, D63, and D100 sizes suit different plant distances and operator visibility. Specify gauge type (glycerin for pulsating, dry for static) and material (carbon steel or stainless) based on environment. We can cross-reference your OEM part number or pressure spec.
Does Preciman provide calibration certificates or traceability documentation?
Standard Preciman gauges are factory-set; specific calibration certificates or NIST traceability are available on request as special-order items. For regulatory or audit requirements, consult us on lead time and cost. Most plant environments treat these gauges as field indicators rather than certified measurement standards.
