A pressure gauge is an instrument used across many industries, like construction, oil drilling, and for other industrial applications. As the name implies, it’s a tool that helps operators calculate the air pressure at various levels of elevation. Pressure gauges are installed on tower cranes to indicate any hazardous lifting situations.

Here are some of the most frequently asked questions about pressure gauges:

What is a pressure differential?

Pressure differential, also known as PD, is the difference between two pressures. PD is measured relative to the pressure in the atmosphere at that time. It depicts the difference between two pressure points.

How can the ideal pressure be determined?

Through a pressure gauge to check the pressure on the device and compare it to the required pressure for the particular application. Since pressure gauges are used for so many different applications, there’s no “one size fits all” answer. Pressure gauges also come in a variety of calibrations, from 0 to 15 psi. It’s essential to choose a pressure gauge that’s appropriate for the required application.

How can the pressure gauge be calibrated?

Calibrating a pressure gauge isn’t a simple process. It’s complex and can be quite difficult too. Every pressure gauge has its own calibration technique, making is a task best left to the professionals. Hire the services of a reliable and experienced professional to correctly calibrate the pressure gauge for you.

What’s the installation process?

Pressure gauges are installed into a pipe fitting with the help of a mount. This mount usually comes with the gauge, but in some cases may be sold separately too. Some pressure gauges have a threaded mount located at the bottom, making it easier to install.

What does a negative reading signify?

If the pressure gauge is showing a negative reading, it’s a sign that there’s something wrong with the device. Air pressure is always measured in positive numbers and therefore, a negative reading is an error. Have the pressure gauge fixed by a professional. The wrong calibration of the device can also lead to a negative value being displayed. Consider having a new one installed, one that’s better quality and more reliable.
