Testing and Calibration of Temperature Gauges using Webcam based Non-Invasive Technique
In this paper, a contact less testing and calibration system is developed for temperature gauges. The system captures the images of temperature gauge at a regular interval, detects the desired region of interest using algorithms and segments the needle for further processing. The segmented image properties are calculated and matched with the standard data to indentify the indicated value. The s...

متن کاملEvaluation of Non-Nuclear Gauges to Measure In-situ
Executive Summary A study was conducted to evaluate if the commercially available non-nuclear density gauges could be used to determine density of hot-mix asphalt (HMA) pavements. Comparisons were made, both in the laboratory and in the field, between accepted density values of HMA and density obtained from both the Pavement Quality Indicator (PQI) and the PaveTracker. A laboratory study conduc...
متن کاملA Portable Immunosensor with Differential Pressure Gauges Readout for Alpha Fetoprotein Detection
A portable, affordable and simple detector is requested in a "Point-of-Care-Testing" (POCT) system. In this study, we exploited the potentialities of Differential Pressure Gauge (DPG) to the orientation of POCT technology. Alpha fetoprotein (AFP) was chosen as a model analyte that could specifically recognized by its antigen, and a tiny outfits equipped with a DPG was employed as the signal rea...
متن کاملComputer Controlled Automatic Calibration System for Dial Gauges
The calibration of dial gauges is a time consuming, cumbersome and monoton process. Due to monotonety the probality of human errors is large both in capturing the measuring data and in it’s evaluation. In order to maintain competitivness automation became compulsory. The present paper describes the design and implementation of an automatic calibration system applying advanced computer technolog...
