System for inspection of fuel level sensor

Abstract

This document describes a project developed for the company BorgWarner S. de R.L. de C.V. Chihuahua plant, which is dedicated to the manufacture of gasoline modules. The gasoline modules are made up of three main elements: the gasoline pump, the gasoline filter, and the fuel level sensor. When a fuel level sensor is found to be defective during manufacturing and testing, it is sent to the quality department for inspection. The root cause of the failure must be found in order to improve production processes or determine if the materials that make up the product are adequate. A system for the inspection of fuel level sensors implemented in the quality department of this company is presented. The developed system generates graphs of the sensor resistance depending on the position of the float, which allows detecting failure points in it.
