Choosing the right gauge depends first on what media you’re measuring and the pressure range.

For general industrial applications with stable, clean fluids (air, water, oil) and standard-to-high pressure ranges, WIKA’s Bourdon-tube gauges are often ideal. They offer broad range coverage and rugged reliability.

If you’re measuring low pressures, vacuum, or need greater sensitivity — or if the media is corrosive, viscous, or particulate-laden — then a diaphragm (or capsule) gauge may be more appropriate, because its sensing element better tolerates challenging media and is less prone to clogging or damage.

You also need to account for environmental conditions, compatibility of the process fluid with wetted parts, and required accuracy — WIKA offers different materials and configurations to match those needs.

In short: for standard pressures & clean media → Bourdon; for low pressure, aggressive media or special fluids → diaphragm/capsule.

Best practice is to select a gauge whose full-scale pressure range is roughly 2× the highest normal operating pressure of your system. That gives margin for pressure spikes and ensures longevity.

For accuracy: many standard industrial gauges are fine for everyday monitoring, but if you need tight measurement tolerances or precision control, choose gauges with higher accuracy classes (as offered by WIKA — ranging from industrial-grade to test-grade, depending on the model).

Also, if your system experiences significant pulsation, vibration, or fluctuating loads, it’s often safer to overspec the gauge rather than rely on the bare minimum — and consider a liquid-filled gauge for stability.

Material compatibility is critical. For clean, non-aggressive media (like air, water, standard oils), standard brass/copper-alloy gauges may be suitable.

However, when dealing with corrosive fluids, acidic media, slurries, or chemically aggressive substances, you should choose gauges with stainless steel, Monel?, Hastelloy?, or other specialty wetted parts. In many such cases, adding a diaphragm seal is recommended to isolate the process fluid from the gauge internals — preventing corrosion, clogging, or contamination.

Additionally, for harsh environments (vibration, pulsation, temperature extremes), WIKA offers liquid-filled case options and different mounting/connection styles to maximize durability and reliability.

Yes — WIKA gauges can be configured to handle challenging operating conditions, but the right options must be selected:

For systems with vibration or pressure pulsation, choose a liquid-filled gauge (e.g., glycerin, silicone, or inert oil) — the fill fluid dampens needle flutter and protects internal mechanisms.

If the media is corrosive, contains particles, or may crystallize, pair the gauge with a diaphragm seal or isolating accessory. That prevents direct contact between harmful media and the gauge’s sensing element, increasing service life.

For extreme temperatures — e.g., steam or high-heat media — consider additional protective accessories like pigtail siphons, cooling elements, or remote mounting via capillary tubing if needed.

Finally, always ensure the gauge is installed per manufacturer recommendations (correct mounting position, compatible process connection, and proper maintenance) to guarantee longevity.

Purchasing WIKA gauges through Valin offers several advantages beyond just getting the instrument:

You get access to expert support, including assistance with selecting the correct gauge type, pressure range, materials, mounting style, or accessories — helpful if your process conditions are complex or non-standard.

Buying from a trusted distributor helps ensure you receive genuine WIKA products, full traceability, and warranty compliance — which is critical for process safety and regulatory compliance.

These benefits make Valin more than a supplier — we’re a partner in helping you design, install, and maintain pressure measurement systems that work reliably under real-world industrial conditions.
