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

Answer / sreenivasulu
wheat stone bridge is used for measuring resistance and
pirani gauges are used for measuring small pressures and
strain gauge is depends on the principle of when strain is
applied to conductor the length increases and resistance
increases

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.

Answer / malhotra g singh
WHEATSTONE BRIDGE IS INVENTED BY WHEATSTONE.PIRANI GAUGE
AND STRAIN GAUGE ARE INVENTED BY PIRANI AND STRAIN
RESPECTIVELY.WHEATSTONE BRIDGE IS A BRIDGE WHEREAS PIRANI
GAUGE AND STRAIN GAUGE ARE GAUGES.

Steve said that "An eddy-current probe works by passing an alternating current through a coil of wire and measuring the coil’s impedance" while we are using -24 Volt DC , So I am confused about DC and AC. Plz .
