Answer / www.islamqa.com

wheatstone bridge used in many circuits for variety of
purposes , it's main idea is to change 1 resistor of 4
resistors and get this resistance change in form of voltage
change.

Strain gauge is a "pressure sensitive resistance" which
attached to the wheatstone bridge to consist "pressure
transmitter"/pressure monitoring system.

R chnage by pressure as R=L*(ROH)/A , L:LENGTH and A:AREA
are changing by pressure , this leads to R change.
