Introduction Semiconductor strain gauge uses the property of piezoresistive effect in few semiconductor materials such as silicon and germanium to achieve greater sensitivity and higher levels of output. Semiconductor gauges …
Structure- In Unbonded strain gauge, fine resistance wire of diameter 0.003mm or less is stretched between two frames P & Q using insulated pins. Here both the frames can move …
Structure- In bonded strain gauge, a fine resistance wire of diameter 0.25mm or less is bonded or pasted on a thin flexible sheet of a paper, tissue, Bakelite or Teflon …
There are various types of strain gauge sensors widely used in industries. A broad classification is shown as follows- Wire wounded strain gauges Bonded wire strain gauge Unbonded strain gauge …
Gauge Factor is defined as the ratio of relative change in electrical resistance to the mechanical strain. Here relative change in resistance is defined as the ratio of change in …
Strain Gauge is a variable resistive transducer which is used to measure strain or change in length or distance produced by external force (i.e. expansion and or compression) or pressure. …
“Passive Transducers are the transducers which require external power for the measurement of process variable or or processing of output from primary sensing element (Sensor). These are also known as …
“Inductive transducer is also called as Variable Inductance transducer. When a physical quantity to be measured, such as motion, displacement, vibration, acceleration, force, speed etc. make changes in inductance properties …
Capacitive transducer is also called as Variable capacitance transducer. When a physical quantity such as temperature, pressure, displacement, vibration, force etc. make changes in capacitance or relative capacitance for …
Resistive transducer is also called as Variable resistance transducer. Resistive transducers are those devices in which resistance varies due to effect of physical quantity to be measured. When a physical …
