About Pressure Transducer

A pressure transducer is used to convert a certain value of pressure into its corresponding mechanical or electrical output. Measurement if pressure is of considerable importance in process industries. Types The types of pressure sensors are differentiated according to the amount of differential pressure they are able to measure. For low differential pressure measurement Liquid Column Manometers are used. Elastic type pressure… Read More »

About Vacuum Gauges

About Vacuum Gauges For pressure measurement below atmosphere or vacuum  gauge, different gauges are available. Manometers and bell gauges can go up to 0.1 Torr. Diaphragm gauges are usable up to a pressure of 10-3 Torr. For pressure below this value, electrical gauges like Pirani or Ionization Gauges are used. Vacuum measurement is broadly classified into Mechanical Type, Thermal Type, Ionization Type, and Radiation… Read More »

Absolute Pressure Gauge

Absolute Pressure– This is a combination of gauge pressure of the media with the pressure of the atmosphere. When the location changes, say as per the change of altitude, the atmospheric pressure also changes which compel the reference point to differ as well. If an absolute pressure sensor is used for eliminating the reference of varying atmospheric pressure.

How differential pressure gauges influence the success of process control applications with many measurement variables.

In the world of process control there are many measurement variables, generally falling under the categories of pressure, temperature, level, and flow. Instruments for measuring these variables allow system operators to monitor the condition and movement of liquids and gases. Differential-pressure gauges are widely recognized as the largest “specialty type” pressure gauge category. They are used in filtration,… Read More »

Terms related to pressure

Terms Related To Pressure Terms Related to Pressure Atmospheric pressure: The pressure due to air surrounding the earths surface is called as atmosperic pressure. Absoulte pressure: It is known that pressure is force per unit area when the interaction of fluid particles among themselves is zero, a zero pressure intensity will occur. This is possible only when the… Read More »
