GRINDING PROCESS
A cylindrical grinding process finishes most wheel spindle surfaces. It is essential that this grinding process leave a surface finish that is smooth and free of defects with minimal runout. No grinder produces a perfect surface. Grinder wheel runout, improperly dressed wheels and fixture vibrations can cause chatter on the spindle surface finish. Chatter is a series of microscopic, repetitive imperfections, or waves, in the surface of the material being machined. The required production environment sensor must have small spatial resolution, high frequency response and large standoff distance for easy loading and unloading of parts. Additionally, the measurement accuracy had to be [...]

MTI Instruments Whitepaper: Capacitance Guide for Industrial Applications
Capacitance Guide for Industrial Applications This guide from MTI Instruments explains what you need to know about using electrical capacitance for measurement in industrial applications, including advanced manufacturing. Basic Principles Capacitance is the ratio of the change in an electric charge to the corresponding change in its electrical potential (i.e., voltage). Capacitors, components that that have the “capacity” to store an electric charge, consist of conductive parallel plates that don’t touch or connect with each other. Instead, these metal plates are electrically-separated by air or a layer of insulating material (i.e., the dielectric). MTI’s [...]

Whitepaper: Why Capacitance? Benefits and Applications of Digital Capacitive Sensors
Industry applications illustrate the versatility and benefits of today's digital capacitive sensor technology. The electrical capacitance formed between a capacitance probe and target surface varies as a function of the distance, or gap, between those two surfaces.
High Precision Portable Signal Generators and Calibrators: Everything You Need to Know
High precision portable signal generators are portable electronic devices that generate highly precise signals for testing, system calibration, sensor simulation, troubleshooting, and monitoring. Unlike the benchtop signal generators that are used in laboratories, these hand-held portable devices are designed to be used in the field. The best high precision portable signal generators are also rugged and NIST traceable, meaning that their manufacturer calibrates them to standards from the National Institute of Standards and Technology (NIST). In terms of cost, high precision portable signal generators are more expensive than less precise, lower-end devices that can be held in the hand; [...]
Thickness Information of Composite Materials
Thickness Information of Composite Materials Industrial Thickness Information Of Composite Materials Thickness Description Introduction: 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 [...]
