Capacitive vs. Eddy Current Sensors: A Comparison for Non-Contact Measurement
Capacitive vs. Eddy Current Sensors: A Comparison for Non-Contact Measurement Capacitive vs. Eddy Current Sensors: A Comparison for Non-Contact Measurement Manufacturing Ev Battery Production Thickness, Distance This application note from MTI Instruments compares two widely used types of non-contact sensors: eddy current sensors and capacitive sensors. It covers their basic operating principles, provides a quick comparison, and offers guidance for selecting the right sensor for your application. Capacitive Sensors: Operating Principles and Applications Capacitive sensors use electric fields to measure the distance between the sensor face and the target surface. These sensors are particularly effective [...]
Thickness Measurement of Dielectric Materials
Thickness Measurement of Dielectric Materials Manufacturing EV Battery Production Thickness, Distance --- Description --- Introduction Many applications, both in manufacturing and research, require precise material thickness measurements. This becomes especially difficult if the material is moving, is non conductive and/or translucent to clear. The specifics of your application may make accurate measurements difficult; many circumstances prohibit contact measurement, and make laser measurements difficult or impossible, for example with thin clear materials such as glass, sapphire, plastic . In cases such as these, capacitance measurement provides a highly accurate and cost-effective solution. [...]
Angle Measurement And Monitoring
Angle Measurement And Monitoring Industrial Angle measurement and monitoring Robot Guide Introduction What do sheet metal, speakers, and wine bottles all have in common? They all require precise angle measurement to ensure product consistency and quality. Whether you're working in metal fabrication or consumer product packaging, an angle measurement sensor is essential for measuring critical angles and profiles with high precision. Precision Angle Measurement in Sheet Metal Press Brake Applications Many industrial applications, especially in sheet metal fabrication, rely on angle measurement sensors to monitor and control bends. For example, in [...]
Pipeline Testing
Pipeline Testing Customer Case The customer wants to test pipelines for corrosion and cracks. They intend to use a small robot which they can send into the pipeline. This robot's purpose is to test the pipe by ultrasound and magnetic field for cracks, corrosion and other damage. The customer is using 2 different types of transducers, one for ultrasound and one for the magnetic field. They are sending a pulse with a magnetic field generator, capturing the received signal, rotating the transducer 1/2 degree and then sending another pulse and capturing signal again. After a complete 360 degree rotation, [...]

DC Motor / Commutator Bar
DC Motor / Commutator Bar Industrial Dc Motor / Commutator Bar Depth Description Using a MTI Microtrak 4 laser triangulation sensor to measure a DC motor’s armature / commutator bar run out. We fitted a DC motor armature (rotor) in a lathe to spin it. The MTI laser head a DTS 50-20 has 50 mm standoff and a 20 mm measuring range. The laser was placed in a FS-5 magnetic  mount fixture and pointed at the commutator bars. The lathe was spun at 180 RPM and the commutator bar run out [...]
Hopkinson Bar Testing (Stress Pulse Reaction Testing)
Hopkinson Bar Testing (Stress Pulse Reaction Testing) Customer Case This customer is involved in testing materials for how they react to stress pulses. The idea is to introduce a stress pulse into the Material Under Test (MUT) and monitor it as it travels through the material. This method of material characterization is also known as "Hopkinson Bar" testing. Multiple sensors pick up the reaction of the material and provide outputs which need to be digitized. These outputs are transient signals of approximately 2 Volts and have a rise time of approximately 600 nanoseconds. The resulting system must be programmable [...]
Cement Board Quality Control
Cement Board Quality Control Industrial Cement Board Quality Control Dimensions Description Introduction: Cement backer board is used as underlayment for tile floors, walls and counter tops. It is also used as exterior sheathing and in exterior stucco systems. Cement backer board has proven to be more durable than virtually any other underlayment if quality control and thickness is maintained. The Problem: A major cement board manufacturer was faced with the challenge to improve a board production line throughput and decrease the amount of waste in the process. Too thin of cement board [...]
Extruder Die Flatness
Extruder Die Flatness Industrial Extruder Die Flatness Thickness Description Introduction: Extruder dies have a flatness specification that must be maintained or the parts being extruded will be out of tolerance and non-conformant, resulting in scrap and disruptions. Periodic inspection of the die for flatness, deformation, burrs, or other irregularities is required. Situation: A tool and die company approached MTI Instruments, requesting assistance with a new method for inspecting their 20 ft long die. Contact gauges on a gantry had been the previous method; Non-contact was now the preferred practice. Solution: [...]
