Instrumentation & control system india manufactures micro-ii air electronic air gauge and multi gauging fixtures. Microprocessor operated micro-ii air electronic air gauging works on the back pressure type air gauging principle. The micro-ii incorporates specially developed, highly sensitive `ceramic pressure sensor` works on the principle of `piezio-resistive resistive pressure transducer which measures the` differential pressure between the air gauge member and mag control orifice and the zero control knob and the inlet pressure. The` ceramic pressure sensor` provides` stability from drifts` and generates electrical signal which is directly proportional to the `differential pressure` between the two channels for the micro processor to process by proprietary electrical circuitry and , display the` exact diameter` of the component being measured on the back lit lcd screen. Micro-ii utilises dsp [digital signal processing] to generate `analog bar graph` and digital displays. The large display is highly readable - exceeding the size of those in competitive instruments.
