Scanner and Display Installation on Petrol Engine Test Rig: Review

Abstract

In this project, we are going to develop a temperature scanner with display. It is a device that measures more than one temperature points or multi-channel. It is actually a multi-channel indicator that measures and displays signals of each channel one-by-one up to last channel and then returns to first channel and continues the process cyclically. This continuous cyclic process of measurement is called scanning. By using a temperature scanner, temperature of multiple points can be measured in a single unit, thus saving cost and space. Thus temperature scanners are also called as multi-point indicators/scanners. Temperature scanners are essentially based on digital technology or microprocessor/microcontroller. It is capable of measuring temperature from resistance temperature sensors like RTD Pt100 or from different types of thermocouples like J, K, R, S, T, B, E and N. In the petrol engine test rig, there is old system of measuring temperatures with the help of thermo couple which is old, unreliable and faulty. Also, electrical noise is another important parameter which affects the system. Due to these parameters, wrong temperatures are displayed which affect calculation of heat balance sheet and thus entire thermal analysis of diesel engine. By installing scanner, more accurate and precise temperature readings will be displayed which will help to analyze thermal efficiency of engine more accurately
