How to Implement a Complete Digital Closed Loop Control System
Co-authored by Don Welch, Director of Engineering and Business Development Cory Bufi, Software Engineer Isaac Abbott,Product Innovation Engineer – PBS Group Request Whitepaper Today’s electronic designs often call for reasonably fast and precise positioning of miniature components for process deposition elements such as ink jet nozzles, 3D printing elements etc. And as process control moves from mm positioning to micron to sub-micron positioning it becomes necessary to monitor and control positioning actuators such as piezo flexure stage and voice coil motors. Open loop control of the positioning stage may have been adequate in non-precision applications but piezo electric [...]
Treadmill Power Glitch Monitoring
Treadmill Power Glitch Monitoring Customer Case A customer develops gym equipment such as treadmills. The requirement is for an inexpensive way to monitor voltage signals for long periods of time. The treadmills are controlled by microprocessors that drive the LED displays. The customer has observed that some units intermittently fail during testing, a condition known as a "glitch" or a "brown-out". A glitch can have many causes, one of which is a weak power supply. The customer needs to capture certain key signals when a glitch occurs. At that stage, based on the captured data, it can be determined [...]

Measuring Brake Rotor Thickness Variation with Capacitive Sensing
Brake rotor thickness variation, or disc thickness variation (DTV), causes uneven wear to brake rotors, disc-shaped automotive parts that are squeezed between brake pads to slow or stop a vehicle’s wheels. When a brake rotor has areas of different thickness, the amount of clamping force that’s applied across the rotor’s surface varies. These differences in clamping force lead to difference in torque, and the results may include brake shuddering, pulsating, or vibration. Even under normal driving conditions, brake rotors are subjected to extreme conditions that can cause performance-related issues. To ensure that brake rotors can perform [...]
White Paper: High Accuracy, High Voltage Measurement – April, 2019
Introduction One of the first principals learned as an engineering student is the “observer effect” which states that simply observing a situation or phenomenon necessarily changes that phenomenon. This is often the result of instruments that, by necessity, alter the state of what they measure in some manner. Accurate high-voltage measurement is a clear example of the validity of this theory. The accuracy of the resulting measurements is affected by three important elements: environmental factors, errors that are introduced by the measurement probe, and the intrinsic accuracy and performance of the measuring instrument. This article will address each of [...]
Capacitive Displacement Sensors: Working Principle & Precision Measurement Applications
Capacitive Displacement Sensors: Working Principle & Precision Measurement Applications Capacitive displacement sensors are precision non-contact measurement devices that utilize capacitance changes to determine position, distance, and thickness with exceptional accuracy. These capacitive distance sensors offer superior performance in applications requiring high-resolution measurements, making them essential tools across manufacturing, automation, and research industries. How Capacitive Displacement Sensors Work Capacitive Sensor Working Principle Capacitive displacement sensors operate on the fundamental principle of measuring capacitance variations between two conductive surfaces. The sensor probe acts as one plate of a parallel plate capacitor, while the [...]

Proforma 300i SA Video Shows Semiconductor Metrology
MTI Instruments, a worldwide leader in precision measurement solutions, has released a YouTube video that shows how its Proforma™ 300i SA semi-automated measurement tool measures silicon carbide wafers for semiconductors. George Relan, MTI’s Global Director of Sales, demonstrates how the desktop metrology system provides non-contact full wafer scanning and 3D mapping of measurement features such as thickness and shape. MTI’s video also shows how the Proforma 300i SA interfaces with an external computer and provides powerful Windows-based software for analysis and reporting. By utilizing MTI push/pull technology, the Proforma 300i SA doesn’t require the semiconductor wafers to have a [...]

Navy Orders Avionics Test and Measurement Systems
The U.S. Navy wants new avionics test and measurement systems. Under the terms of a $109-million award, the Naval Air Warfare Center Aircraft Division in Lakehurst, New Jersey will buy 41 electronic consolidated automated support systems (eCASS) from Lockheed Martin. This test and measurement equipment helps soldiers and Marines troubleshoot and repair aviation electronics while at sea. Avionics, the electronics used in aircraft, support essential navigation and communications functions. With military aircraft, avionics typically include electro-optical, infrared, and other types of sensors for airborne radar, weapons systems, and heads-up displays. Military avionics also need to support electronic warfare systems, [...]
