The types of pressure measuring instruments are divided into liquid column type, elastic type and electric measuring type according to the working principle. The pressure gauge can indicate and record...
1. Absolute pressureThe pressure with absolute vacuum as the zero reference.2. Positive pressureA pressure more than atmospheric pressure based on atmospheric pressure.3. Negative pressureThe pressure...
Here are the different types of pressure gauges:1. Liquid column pressure gaugeThe liquid column pressure gauge is based on the principle of statics, which converts the measured pressure into the heig...
In the production field, pressure gauges are often used for pressure measurement. In different working occasions, the use requirements and performance requirements for pressure gauges are different, s...
Because the current at the contacts of SF6 density relay is small, there will be no arc between the contacts. The sparks at the contacts are due to the inductance in the contact circuit. When the cont...
The measuring system is essential for pressure gauging. Correct selection and verification (calibration) of the pressure gauge are very important for accurate measurement. Besides, correct installatio...
When selecting a pressure gauge, you need to consider the type, range, accuracy, sensitivity, dimension, remote transmission function and other functions such as indication, recording, adjustment and ...
