Errors of non-contact temperature measurement

Izvestiya. Ferrous Metallurgy, 2023
In recent years, there is a trend of improving the performance and efficiency of all existing measuring instruments due to a leap in technology. Almost every industry uses a variety of technologies that apply temperature control. Temperature of a heated body can be estimated by measuring the parameters of its thermal radiation, which are ...

Non-Contact Coating Thickness Measurement

International Thermal Spray Conference, 1998
Abstract There are many instances of coatings that require a nondestructive and non-contact measure of coating thickness as part of a quality control system. Specifically, this paper reports on experiments carried out on non-contact measurements of MCrAlY and TBC coatings.

Non-Contact Measurement of Line Voltage

IEEE Sensors Journal, 2016
This paper presents a capacitively coupled non-contact voltage sensor, which is specifically optimized for monitoring line voltages ranging from plug level to distribution levels at thousands of volts. The sensor uses a new arrangement of electrostatic pickups to measure the rate of change of an unknown potential, and digitally integrates that the rate

Design of Non-contact measurement System

2020 5th International Conference on Mechanical, Control and Computer Engineering (ICMCCE), 2020
Based on embedded system, this system designs and realizes the non-contact measurement of object size and shape. In this system, images are processed on the machine vision platform, while edge detection is performed using Canny operator. Hough transform is used to judge whether the object is circle, quaternion detection method is used to judge whether ...

A DIGITAL NON‐CONTACT MEASUREMENT SYSTEM

The Photogrammetric Record, 1993
L'industrie liee au gaz et au petrole au large, en Mer du Nord, a de nombreux besoins de mesures a trois dimensions effectuees en aerien ou sous l'eau. Il y a de nombreuses annees que la Camera Alive a utilise les techniques photogrammetriques pour satisfaire a ces besoins.

Non-contact length and speed measurement

2008 International Conference - Modern Technique and Technologies, 2008
Every manufacturer wants to keep track of product quality and quantity during the production process. But when the manufacturer is producing cable, that's not as easy as it may sound. Manufacturers typically utilize contact encoders to measure product length and speed during production.

Non-contact measurement of contact wire

SPIE Proceedings, 2008
The overhead contact system is the power supply unit of the electric locomotive. This article is to introduce our newly developed method to measure the height and pull out value of the contact wire. A carema dolly which can move on railway is applied to bear the weight of the measure equipment; two linear CCD cameras are installed on the dolly ...
