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 [...]
MTI Case-In-Point: Gap Monitor Keeps Wind Turbines Running
Gap Monitor Keeps Wind Turbines Running System helps operators minimize downtime and protect against catastrophic failure Introduction Wind turbine production has been steadily increasing to meet growing demand for renewable energy. As power outputs and the number of installations climb, maintenance becomes ever more critical. Operators want to minimize downtime and protect against catastrophic failure. The ability to predict when maintenance will be required can go a long way to ensure these goals are met. Challenge A leading manufacturer of wind turbine power generators approached MTI for critical gap monitoring sensors. Specifically, the company wished to monitor [...]

MTI Application Note: Testing for Connector Failure Due To Vibration or Shock
Testing for Connector Failure Due to Vibration or Shock Mobile Communications Equipment Needs Reliable Connectors That Will Not Disconnect with Shock or Vibration Introduction A large multinational company approached MTI to provide a sensor capable of measuring displacement that also wouldn’t load the target (connector). Shock and vibration testing would span 2-15G and the target connectors were very small. Application MTI’s 2100 optical displacement sensor system is ideal for this kind of application because very small probes can be used and they measure displacement via reflected light. [...]
Application Note: How to Ensure Your LED Lighting Products Meet Industry Standards
Testing for performance, energy effeciency, consumption verification, quality and safety compliance during product development. Introduction Manufacturers and users of LED lighting products need to ensure that their products meet the qualifications and requirements of a multitude of reliability and efficiency standards. In addition to voluntary initiatives and programs like EnergyStar, mandatory standards and specifications for the lighting industry must be kept in mind during project development, including the latest IES LM-79-19 and the ANSI C82.16 documents. This application note provides an overview of relevant lighting standards and specifications for LED lighting products. [...]

GaGe Application Note: Creating a Data Link Signal Integrity Test Platform
Download a PDF Copy of this App Note Data Link Device Testing The data link device under test (Figure 1) is characterized by comparing test signals that are input to the link with signals measured at the link output. Differences between these two test signals indicate a degradation by the link during transmission. Figure 1. Two test platforms (PCIe and PXIe, respectively) transmit and receive the data link test signals. GaGe RazorMax high-speed data acquisition cards record the data for signal integrity comparison. The input and output test signals require sampling at 1 GS/s (GigaSample per second) [...]

A Comprehensive Guide to Non-Contact Sensors and Their Applications
Sensors, both contact and non-contact, are crucial devices that allow the monitoring, detection, and reaction to conditions in an environment or within a process or piece of equipment. While myriad types of sensors exist and are designed to monitor varying conditions, all of them can be characterized as being one of two types — contact sensors and non-contact sensors. We’ll focus on the latter, diving into different technologies, types, and applications of non-contact sensor technology; but first, let’s explore what differentiates contact and non-contact sensors. Contact vs. Non-Contact Sensors: What’s the Difference? Measuring, monitoring, or detecting a particular condition [...]

Digital I/O ASIC Testing
Digital I/O ASIC Testing Customer Case A customer needs to generate stimulus to test his Application Specific Integrated Circuits and to capture response from that ASIC. The stimulus definition exists as an ASCII file with rows and columns of 1s and 0s. Each column corresponds to a different input pin of the ASIC and each rows corresponds to a different time tic (every 50 nanoseconds). The controlling baud clock runs at 10 MHz. The requirement is to record the digital response from the separate output pins of the ASIC as another ASCII file of 1s and 0s. Again, every [...]
