What is Diaphragm Seal on Pressure Gauge or Transmitter？

What Diaphragm Seal is? Diaphragm seal is a mechanical device for separation between the measuring instrument and target process medium. Its main part is a thin and flexible membrane (the diaphragm) that responds to pressure changes in the medium through displacement. When pressure is exerted on ... Read More

Risks of Corrosive Media in Process Measurement

Corrosive media are substances that can cause damage or degradation to surface and structure via chemical reactions. In the context of measurement instrument, corrosive media usually involve liquids or gases that may react chemically with materials of the instrument over time, adversely affecting... Read More

Bimetallic Thermometer Preliminary Understanding

Bimetallic thermometers use a bimetallic strip to convert temperature changes into mechanical displacement. The core operating idea is based on the expansion of metals who changes their volume in response to temperature fluctuations. Bimetallic strips are composed of two thin strips of different ...
