MTI Application Note: How to Achieve <1um Accuracy When Measuring Roller Gap
How to Achieve <1um Accuracy When Measuring Roller Gap Roller Gap Measurement with MTI Digital Accumeasure Capacitive Probes Many roll-to-roll finishing processes typically use a calender, or series of hard pressure rollers, to deliver smooth, high-quality products of plastic, textile, or paper (Fig 1). Ensuring a consistent material thickness, however, depends on the ability to monitor, and maintain, a precise gap between rollers. This application note describes a quick and easy means for roller gap measurement. Problem How to measure the small gap between rollers to keep track of product thickness. Typically, it’s not possible to [...]

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. [...]

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 [...]
TESTING CHARGE AMPLIFIER GAIN AND FREQUENCY RESPONSE WITH A SIGNAL GENERATOR
[Application Note 40518] Piezoelectric transducers produce small electrical charges in response to pressure. Their sensitivity, ruggedness, and stability at high temperatures make them an essential building block of many accelerometers and pressure sensors. Applications include turbine vibration measurement (accelerometers) and combustion dynamics monitoring (pressure sensors). Typically, the high-impedance charge output produced by a piezoelectric transducer must be conditioned and amplified before transmission across system cabling to the data acquisition and measurement instrumentation. This conversion is accomplished with a device called a charge amplifier. Problem Over time, a charge amplifier’s signal response can drift. Damage to the charge amplifier or associated [...]
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 [...]
