Bonded foil strain gauge (BFSG) pressure transducers & transmittersĀ have foil gauges made from materials such as Constantan which are bonded using industrial adhesives to a stainless diaphragm or beam which is the material which flexes in response to change in pressure.
The foil strain gauge sensing element typically includes two or four foil strain gauges which are joined together into a wheatstone bridge circuit.
These type of pressure sensors are most suited to mid to high range pressure measurement and because the sensing diaphragm is stainless steel they are very robust and can withstand high dynamic pressure changes.
