Pressure gauges are essential tools for a variety of industries. They're used to monitor the pressure of liquids and gases, and they're also used to measure pressure in pipelines and other industrial processes.

Pressure gauges are calibrated according to the range of pressure they can measure. However, over time, they can become inaccurate due to wear and tear or damage. In this case, you may need to update your pressure gauges. 

Here are four signs that tell you when it's time to update your pressure gauges;

1. It's Hard To Read The Gauge

If your gauge face has become discoloured or stained to the point where readings are difficult to discern, it needs replacement. Not being able to easily determine where the gauge needle is pointing defeats the purpose of the gauge and prevents you from effectively monitoring your system. Over time, exposure to high temperatures or corrosive chemicals can cause a gauge face to become faded, cloudy or darkened. The numbers and markings on the face may become unclear or obscured. If the lens or crystal over the gauge face is also damaged or cracked, it further impacts your ability to clearly read your pressure gauges. 

2. The Needle Is Sticking Or Jerking 

If your needle is sticking or jerking, it means that you need to calibrate your pressure gauge. This may be because the needle has become bent or distorted, or because the mechanism inside the gauge is damaged.

The first step in calibrating your pressure gauge is to remove any dirt and debris from the dial face and case. Once this has been done, you can carefully bend the needle back into shape by hand. If this doesn't work, you will need to replace the needle altogether or look at new custom pressure gauges.

3. The Gauge Has Been Damaged By Vibration

Sometimes pressure gauges get damaged by vibrations in their environment — especially if they're on a truck or other vehicle that travels frequently over rough roads. Damaged gauges aren't accurate anymore and should be replaced. Custom pressure gauges can be made to fit your gauge cluster perfectly and are designed to withstand heavy vibrations. 

4. The Gauge Has Unreliable Or Unsteady Readings 

If your pressure gauge is giving you unreliable or unsteady readings, you might want to look at new or even custom pressure gauges. There are several reasons why a gauge might not be accurate, like worn-out internal parts, damaged components, or a tired pressure-sensing element. Inconsistent readings can create safety risks or cause your equipment to operate incorrectly,
