See Enlarge Click to Enlarge STRAIN GAUGE EXPERIMENT MODULE. MODEL IBL-AM - 11 Strain Gauge is a passive transducer. This is used to measure the lateral strain exerted on a given surface. This sensor converts a mechanical displacement into a change in resistance. Positioning and quality of bonding the sensor on the surface, largely determines the accuracy. An optional external Whetstone's bridge is used to measure bridge imbalance, which is a measure of strain. A bridge is symmetrical, four-element, circuit that enhances the instrument's ability to detect small changes in the sensor. Four Strain gauge sensors arranged in the bridge configuration, balances out fixed or quiescent voltage drop, allowing magnification of the different signal. This acquired signal is conditioned and computed to indicate actual strain suffered by the surface. In the Strain gauge experimental module, the sensor is bonded on one end of a long rectangular stainless steel metal strip of uniform cross section. This end is fixed firmly to a metallic stand. The other end is freely suspended, similar to a Cantilever. To this free end, weights ranging from 50gms to 1000 gms in multiples of 50 gms are added to create strain (elongation) on the strain gauge strip. A relation between applied stress and measured strain gives the change in resistance of the gauge, explaining the principle of strain gauge transducer.

MODEL IBL-AM - 18 When a uniform metallic cylinder of finite diameter D and length L, which has one end fixed and the other end free to twist, twisted, then the cylinder suffers torsion. The deformation of the cylinder is a measure of torque. Strain gauge/s bonded on the surface of this cylinder, in strategic positions provides scope for measurement of torsion suffered by the cylinder. The experimental module has two mechanical parts, fastened. a) A torque transducer and b) 1 meter long bar of uniform cross section. One end of 1-meter long uniform bar is connected to the free end of the Torque transducer while the other end is connected to a weighing pan. Weights can be suspended at the other end of this bar, such that the torque transducer is subjected to angular rotation, but prevented, as the other end of this cylinder is fixed. Now a relation between the strain measured w.r.t. the applications of different weights are studied. A built-in 3 1/2 digit display indicates the torque in terms of Kgm. For example, a weight of 1Kg, placed at a distance of 1-meter (1000 mm) from the transducer is indicated as 1000 on the digital meter. When the same weight 1-Kg placed at 500mm distance from the transducer it is indicted as 500 on the digital display.
