Why Your Pressure Gauge Keeps Breaking and How to Solve This Problem

Understanding Pressure Gauge Failures: Common Causes and Practical Solutions

Are you experiencing frequent pressure gauge failures? You're not alone. Pressure gauge breakdowns are a common challenge in industrial settings, but the good news is that most failures can be prevented with the right knowledge and equipment choices. Let's explore the most common causes and their solutions.

1. Corrosive Media Damage

The Problem: If your pressure gauge is measuring corrosive media, standard materials may deteriorate quickly, leading to premature failure and inaccurate readings.

The Solution: Upgrade to pressure gauges made with corrosion-resistant metals specifically designed for harsh chemical environments. Different corrosive substances require different material specifications, so it's essential to match your gauge material to your specific application. Not sure which material is right for your needs? Consult with your supplier or contact us – we're here to help you select the perfect gauge for your application.

2. Vibration-Induced Failures

The Problem: Is your pressure gauge mounted on vibrating machinery? Constant vibration can damage internal components, cause needle flutter, and significantly reduce gauge lifespan.

The Solution: Switch to liquid-filled pressure gauges, which use glycerin or silicone to dampen vibrations and protect internal mechanisms. Here's a pro tip: smaller dial pressure gauges actually last longer on vibrating equipment. If you're currently using 4" or 6" dial gauges, consider downsizing to a 2.5" glycerin-filled gauge – this simple change can dramatically extend your gauge's service life.

3. Extreme Temperature Challenges

The Problem: Operating in very high or very low temperatures? Glycerin-filled gauges may not be your best choice. At high temperatures, glycerin can boil and doesn't dissipate heat efficiently. In freezing conditions, glycerin thickens or freezes, severely affecting gauge performance and accuracy.

The Solution: For extreme temperature applications, opt for dry case pressure gauges instead. To further protect your equipment:

• Install cooling siphons to dissipate heat more effectively
• Position the gauge away from direct heat sources
• Use proper mounting accessories to create distance between the gauge and extreme temperature equipment

4. High-Frequency Pulsation Issues

The Problem: Is your pressure gauge needle vibrating excessively? This indicates high pulsation frequency in your system, which can quickly wear out gauge components and lead to failure.

The Solution: Install a combination of siphons and pressure snubbers to dampen the pulsation effectively. These accessories act as shock absorbers for your pressure measurement system, protecting your gauge from damaging pressure spikes and extending its operational life.
