THICKNESS INFORMATION OF COMPOSITE MATERIALS
Composite materials consist of two or more materials which include a substrate or base material such as paper, cotton cloth, or glass cloth along with a resin or adhesive such as epoxy, melamine, or silicone. To make a thermoset laminate, the base material is coated with the adhesive so that layers of material can be pressed under heat and pressure into sheet form. The Problem: Composite material thickness needed to be verified prior to forming or machining. Due to the size of the sheets typical measurement techniques were not suitable. A consistent method to accurately measure the board thickness [...]
TIRE TREAD INSPECTION WITH 1D LASER SENSOR
Tire manufacturers wants to satisfy their customers, and protect themselves from liabilities, manufacturers are moving to 100% tire inspection for defects and abnormalities. Defects not only cause potential safety issues but they can also introduce unwanted vibration into the vehicle suspension system. Belts can be overlapped, or not cover the complete tire surface, causing weak or bubbled areas and imbalances. The tread depth can be too shallow, leading to decreased service life. An uneven tire can cause excessive runout and vibration. MTI was approached by a major manufacturer requesting a solution to measure tread depth, runout and blistering. They [...]
TORQUE CONVERTER
Industry Automotive Applications Torque Converter Measurement Type Surface Description Since minute defects in the torque converter casing wall thickness can result in unacceptable and dangerous torque converter expansion, a precision measurement system was needed to measure the impeller hub displacement and thus the torque converter axial displacement. An AC dynamometer would be required to spin the torque converter at a high rate of speed while a fast response hydraulic system is needed to pressurize the converter to pressures up to 150 psi. MTI’s MicroTrak laser sensor was selected because it offered [...]
FIBER OPTIC PROBES MEASURE STATOR BAR VIBRATION
[Application Note 11718] One of the primary concerns in large generator design is vibration. Excessive vibration can lead to premature breakdown of insulation and other materials, ultimately resulting in early failure of the generator itself. The Problem A leading manufacturer of power generating equipment required a sensing system able to measure stator bar vibration in a partial generator mockup. Specifically, the company’s multi-day testing program demanded a sensing system that was immune to the large magnetic field generated by live stator bars capable of withstanding high heat built up from prolonged testing, and compatible with a proprietary stator bar [...]
Measurements Using Capacitive Sensors
Capacitive sensors can be divided into two categories based upon their performance and intended use. High resolution sensors are typically used in displacement and position monitoring applications where high accuracy, stability and low temperature drift are required. Quite frequently these sensors are used in process monitoring and closed-loop feedback control systems. Proximity type capacitive sensors are much less expensive and are typically used to detect the presence of a part or used in counting applications. Applications Position Sensing General positioning is probably the most common application for capacitive sensors. As mentioned about, [...]
