This paper is intended to focus on the advanced measurement system, developed for accurate measurements of, dimensions of, a valve guide of an engine. Snap gauges, pneumatic comparators, dial gauges, micrometers, etc are traditional instruments used for inspection. These methods may lead in inaccurate job inspection. So, to overcome the drawbacks associated with traditional equipments, one can develop an advanced measurement system using sensors, actuators and control system. The sensing unit of this system consists of two LVDT probes. Control unit is a programmable logic controller (PLC), while actuation unit has electromagnetic relay and a display. Along with this, a mechanical fixture mounted with LVDT probes is used to hold the job to be inspected. A job to be inspected has to be kept on mechanical fixture. Two LVDT probes which are fixed on fixture displaces as per the job profile. These LVDT sensors are integrated with control unit though an amplifier. Control unit is also integrated with display and a relay. Depending upon the signal received from LVDT, control unit decides which data has to be displayed and whether a relay is energized or not. The relay has control over the machine cycle.
