Explanation: Semiconductor strain gage are much more sensitive than wire type and so, it provide better accuracy and resolution. 5. How a differential instrumentation amplifier using transducer bridge can be used as a temperature controller?
A. Increase room temperature
B. Replaces calibrated meter with relay
C. Change the bridge resistance
D. Replace thermistor by light intensity meter
Answer:A
Explanation: Semiconductor strain gage are much more sensitive than wire type and so, it provide better accuracy and resolution. 5. How a differential instrumentation amplifier using transducer bridge can be used as a temperature controller?
A. Increase room temperature B. Replaces calibrated meter with relay C. Change the bridge resistance D. Replace thermistor by light intensity meter
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
