Explanation: A simple and inexpensive temperature controller can be constructed by replacing a meter with a relay in the circuit. So, the output of the differential instrumentation amplifier drives a relay output of the differential instrumentation amplifier drives a relay that controls the current on the heat generating circuit. 6. The strain gage elements in the analog weight scale are mounted on a
A. Base of weight platform
B. Hanging weight platform
C. Loading weight platform
D. Varying weight platform
Answer:A

A. Base of weight platform B. Hanging weight platform C. Loading weight platform D. Varying weight platform
Explanation: The strain gage elements are mounted in the base of the weight platform. So, that whenever external force or weight is applied to the platform, one pair of element in the opposite arm of bridge elongates, whereas the other pair in opposite arm compresses. 7. What will be the resultant circuit, when the thermistor in the bridge transducer is replaced by a strain gage?
