Pressure Calibration Procedure

What is a Pressure? Pressure is everywhere and all around us. We can feel the air pressure exerted on our body. We feel the pressure during a long travel usually from a low to high elevation or vice versa, we … Read More

The analog pressure gauge is one of the simplest, mostly used instruments, and the easiest to calibrate in pressure calibration. It has a simple setup where you can easily execute the calibration. But analog pressure gauge is also one of … Read More

Measuring or verifying the airflow coming out from the output end of the duct is very simple, an easy way is to use a vane anemometer. A simple placement of the vane (fan) in front of the opening of the … Read More

One of the simplest but most important instruments that I encounter which are used not for displaying or monitoring the process, but for safety, is the pressure safety valves. When I was just starting out as a cal tech, looking … Read More

Are you familiar with this type of pressure sensor? I cannot remember when is the last time where I calibrated this type of pressure instrument that is why  I am excited to present it with you. I was amazed the … Read More

During my learning days, when I hear a pressure transmitter (and other transmitters), it seems it is a very complicated instrument to calibrate (How about you?). . But when I already learned and experience calibrating it, I can say that … Read More

  Pressure gauges have various types and usage, and one of this was a differential pressure gauge. A differential pressure gauge is not just used to measure and display a pressure reading but it is also used as an instrument to … Read More

There are many types of switches which are used in different processes and one of them is the pressure switch. A switch is used to cut or supply a power in a circuit. As the name implies, it is a … Read More

Have you encountered a pressure gauge with two entry ports where pressure can be applied? In this post, I will discuss what is a differential pressure gauge, where it is being used and how to calibrate specifically a Dwyer Magnehelic gauge … Read More

There are different methods and reference standard used to calibrate a pressure gauge.  Most are portable, small, and a good use for on-site calibration. In my other post, I introduce the calibration of pressure gauges using Fluke 754 with a … Read More
