Design a resistance strain gauge type pressure transducer, with the following specifications: Maximum pressure, to be measured 2 bar Diameter of steel diaphragm 8 cm Size of resistance gauges used 3 mm x 6 mm Resistance of each gauge 120 n Gauge factor = 2 Find the thickness of the diaphragm, sensitivity of the transducer and other parameters of the trans- ducer. It is required to measure and plot the pressure in the cylinder of a single cylinder reciprocating air compressor, at several positions in a cycle. Suggest a suitable measuring system, and mention the type of sensor, signal conditioning and recording elements. Draw a sketch and suggest a calibration system.
