Technical notes
USE ADDITIONAL LENS OR OPTICAL BOOSTER TO INCREASE DETECTION DISTANCE
The aim of this technical note is to present the optical solutions offered by OPTEL-TEXYS to increase detection distance. Examples from customer projects will be used to illustrate the different scenarios.
HOW TO DETECT FROM AN OPTEL-TEXYS SENSOR? WITH OR WITHOUT ZEBRA TAPE?
The goal of this article is to highlight the possibilities of performing detections on rotating machines based on some variants of periodic elements.
Detection in Hot Environments with Optical Fibre Sensors
Offering an assembly comprising a sensor and an optical probe is an appropriate response when the measurement environment is restrictive.
This solution avoids prolonged exposure of the sensor to constraints such as temperature, humidity, electromagnetic interference and an explosive atmosphere. In addition, keeping the electronics close to the acquisition system maintains a good quality incoming signal with little phase shift.
ANALYSIS OF TURBOCHARGERS & TURBINES
OPTEL-TEXYS fibre optic tachometers are used in a wide range of applications in the automotive industry, covering the areas of engine and accessory tuning during bench or vehicle testing.
TORQUE MEASUREMENT WITHOUT A MECHANICAL TORQUEMETER
3 French SMEs, including OPTEL-TEXYS, have implemented an innovative optical solution to meet the needs of one of them. CSTM, which develops a high-speed electric motor and needs to measure torque. The company is facing several difficult issues that conventional torquemeters cannot overcome: the measurement must be carried out without added inertia, without integration constraints and at very high speeds.
OPTICAL SENSOR FOR DETECTION IN LIQUIDS
Very often, users are reluctant to use our optical detection solutions when they have to work in environments where liquids are omnipresent.
However, you will see in this article that technical solutions exist to overcome these problems...
SPEED SENSORS DEDICATED TO THE ANALYSIS OF TORSIONAL VIBRATION
Through different work and research made in the Universities of FERRARA and BOLOGNA from which this article is an extract, OPTEL-TEXYS highlights the contribution of its optical speed sensors in the frame of testing and simulation when the goal is to analyse the torsional vibration of a rotating machine in order to solve NVH issues.
