What Is a Pressure Switch? Read Before Buy and Use

What Is a Pressure Switch? A pressure switch is a specialized instrument for pressure measurement and control. Pressure switches can be electronic or mechanical. Based on a preset pressure value, they can open or close the corresponding switch contacts when the pressure is reached. Pressure switches, like pressure transmitters, are essential instruments in industrial processes. However, the two should not be confused. Therefore, you may want to read this article before purchasing or using a pressure switch. RFQ Table of ContentsWhat Is a Pressure Switch?Pressure Switch Working PrinciplePressur......

More Powerful Pressure Transmitter with Diaphragm Seal and Capillary

Diaphragm seal is used to prevent media from directly entering the sensor assembly in the pressure transmitter/differential pressure transmitter. Remote split pressure measurement can be achieved by connecting the fluid-filled capillary tube to the transmitter. Diaphragm seals effectively broaden the application range of pressure transmitters. It makes the measurement of pressure transmitter and differential pressure transmitter safer and more reliable. Diaphragm seal and capillary are ideal choices for protecting pressure instruments and process transmitters even under extreme working conditi......
