1. What are pressure calibrators? Pressure calibrators are exact pressure measuring instruments that can verify and calibrate the pressure value of another pressure measuring device. Pressure calibrators include a deadweight tester, multifunction calibrator, or test gauge. These pressure calibrators provide a faster and easier way to calibrate and maintain pressure-measuring devices with high accuracy in …

What is an error in the pressure gauge? Inaccuracy in pressure gauge occurs when an output signal diverges from the desired value. When the pointer on the pressure gauge scale indicates a higher or lower value instead of actual. What are the factors affecting accuracy and performance in Pressure Gauges? The majority of pressure gauges …
We can define pressure as the force applied over a surface area. When the pressure is applied to a sensor then the pressure-sensitive element would determine the pressure. The pressure sensor would also have certain elements to convert this into an output signal. Mostly a pressure sensor would measure the pressure of gasses and liquids. …

A load cell is a kind of transducer that would convert force into electrical output and this would be easily readable. The load cell can be considered as a force transducer because it can convert the weight or force into an electrical signal. The load cell can be used to measure weight it can be …
A multivariable transmitter is a type of pressure transmitter and this transmitter would calculate the flow using the differential pressure. This transmitter can measure the differential pressure, static pressure, and temperature in a process. This transmitter can be used as a mass flow transmitter, so while using this transmitter like a mass flow transmitter, we …

A diaphragm is a material that would be elastic and if we apply pressure to this then it would displace. This type of pressure gauge would use the elastic property of the diaphragm to determine the difference between reference pressure and unknown pressure. The operating principle of this device is the same as the bourdon …
The piezometer can be used to measure the pressure of the static fluid, this device can measure the pressure of liquids in a container. This device is also called a pore pressure meter because it is mostly used to measure the pore water pressure in the soils, rock fills, and concrete structures. The piezometers are …
