what is difference between wheatstone bridge, pirani gauge
and strain gauge ??? explain its principle and working
Answer Posted / 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.
