Blade Tip Clearance
Blade Tip Clearance Power Generation Blade Tip Clearance Tolerances Description Introduction Large turbines are periodically torn down, inspected, and rebuilt. Turbine blade clearance to the case is one of the most critical measurements. Too close and the blades could expand and the turbine could be destroyed, too far away and efficiency is lost and power is sacrificed. This makes it vital to know the actual blade tip clearance. The inquiry A large multinational company approached MTI Instruments to provide a capacitive sensing system that could inspect blade tip clearance through [...]

Military & Aerospace Applications
Military & Aerospace Applications Military and Aerospace electronics require similar testing for electrical safety as other electronics, but test to different standards. Vitrek's products are ideal for all of your test and compliance applications. Engine Vibration & Balancing Solutions from MTI Instruments In the aerospace industry, engine balancing is of paramount importance for several reasons. Properly balanced engines minimize vibrations, which can significantly enhance passenger comfort and reduce wear and tear on critical components. This leads to improved engine performance, fuel efficiency, and overall safety. Unbalanced engines can [...]
Grinding Process
Grinding Process Automotive Grinding Process Surface Description 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 [...]

Spindle Run Out
Spindle Run Out Automotive Spindle Run Out Distance Description Rotating targets frequently have an intermittent, uncertain or nonexistent ground path. This introduces unwanted noise, instability, drift and reduces accuracy of the measurement. MTI Instruments offers a unique "Push-Pull" capacitance measurement system that does not require a grounded target. It utilizes two probes, built into one body, that work together to complete the ground path. One probe pushes current into the brake rotor while the adjacent probe pulls the current out. The result is a "clean", consistent electrical sensing path. As [...]
Thread Checking
Automotive Thread Checking Presence/Absence Description Manual thread inspection is slow, not always reliable and tedious for the inspector. Manufacturers have struggled to come up with ways to reliably automate the process at a reasonable cost. Automated systems are available that use “screw sensors” can quickly wear or be cross threaded, requiring operator attention and a tooling change. A worn screw can provide false rejections leading to the unnecessary scrapping of parts. Capacitance solutions are cost effective alternative which are becoming increasingly popular due to their high reliability and fast [...]
Piezo Stage Positioning
Piezo Stage Positioning Consumer Electronics Piezo Stage Positioning Description Positioning stages using piezoelectric stack actuators (PEA) have very high resolution. However, it is difficult to achieve precise dynamic motion tracking using traditional linear controllers such as PID due to the inherent hysteresis nonlinearity of piezoelectric materials and the phase lag associated with such controllers. Capacitance Sensors are ideal for measuring the actual piezo stage position and correcting for the inherent nonlinearity through closed loop feedback. They have the stability, bandwidth and high resolution needed to do the job. Several of [...]
Glass Thickness
Glass Thickness Consumer Electronics Glass Thickness Thickness Description Did you know that glass thickness can be measured with a capacitance probe? You will need some equipment: Digital Accumeasure D200 ASP-2500-CTA Dielectric probe (The capacitance probe has a sensing area of 11.25 mm) Range extension = 3X, 10Hz filter Introduction:  An industrial glass fabricator needed a way to determine the thickness of glass, before cutting it to shape and coating it. The glass sample was marked with indices to find the measuring points. The sample center point -5- thickness was checked with [...]
