During The pointer should indicate the direction of movement of the measuring plunger. This apparatus is mainly used for measuring of low pressure as well as the registrars sensor. For example, in a temperature transducer, if 0.2 o C is the smallest temperature change that observed, then the measurement resolution is 0.2 o C. NPTEL - Mechanical Engineering - Forming ... 1.5.1 Contact stress measurement: ... compromise between strain rate, temperature of working and working pressure in order to achieve a formed product without defects. Differential Pressure Theory Perhaps the most frequently used device for the measurement of level is a differential pressure transmitter. Capacitance Vacuum Gauge The pressure sensitive diaphragm of these capacitive absolute pressure sensors is made of Al2O3 ceramics. Therefore we have as follows: where r 1 is the density of the measurand fluid and r is the density of the fluid in the manometer.
