how pressure transmitter work, what is its principal to measure and how its generate signal.
for pressure transmitterinstallation which precautions must be taken ??

Answer Posted / Vivek Chaoudhary

A pressure transmitter measures the pressure of a fluid (liquid or gas) by converting the pressure into an electrical signal. The principal of operation relies on the deformation of a diaphragm or piston caused by the applied pressure, which in turn causes a mechanical displacement that is converted into an electrical signal using sensors like strain gauges or piezoelectric crystals. Pressure transmitters generate signals (usually 4-20 mA analog signals) that are proportional to the pressure being measured and can be easily transmitted over long distances.
