Triaxial Accelerometer for Race Car Performance

Motorsports recognize the need for a triaxial accelerometer that can provide accurate vibration results in pre-race trials and real-time measurements during the course of an actual race. Precise data needs to be gathered to allow the racing engineer to determine what design modifications and suspension adjustments need to be made when mere fractions of a second can determine the winner.

Measurement Specialties, Inc. has developed the Model 4203 accelerometer that satisfies these requirements. The accelerometer features a silicon sensor element utilizing silicon MEMS technology (Micro Electro Mechanical Systems) packaged in a lightweight metal housing. DC capability allows the capture of long duration transients in order to measure whole body motion. On-board signal conditioning outputs high level, low impedance signals. Each of the full scale g-ranges of the three orthogonal axes can be independently selected for optimum measurement resolution.

8400 HighLine Joins Lenze L-Force 8400 Inverter Drives for Motion Control

Lenze Americas, a leading global manufacturer of electrical and mechanical drives, motion control and automation technology, has launched the new 8400 HighLine Inverter Drives, part of the Lenze L-force 8400 portfolio. Designed for positioning applications, the HighLine model features integrated point-to-point positioning for up to 15 position destinations, and stores the corresponding travel profiles directly in the inverter. “Positioning in motor drive systems used to require a separate motion controller. Most applications don’t require a higher cost servo drive. Dynamic speed, torque and precision motion control can be achieved with a powerful inverter in combination with an asynchronous motor,” states Darrow Hanesian, director of inverter products, Lenze Americas. “Our streamlined HighLine delivers all the cost savings and benefits of combining two drive elements—the motion controller and the frequency inverter — into one.” The HighLine inverters’ integrated components transl...

Beko Oil-Vapour Monitor Gains TUV Certification Beko's Metpoint OCV oil-vapour monitoring system for chemical and pharmaceutical production processes has been certified by TUV Nord in accordance with the requirements of ISO 8573-1, Classes 1 to 4. According to the company, even 'oil-free' components give no guarantee for 'oil-free' compressed air, owing to the contamination of the ambient air/intake air. In most cases, a certain residual oil content cannot be entirely avoided in standard applications. The precise monitoring of the oil-vapour content, which is possible at any time, is important. In particular, in critical production processes in the chemical and pharmaceutical industry, in food production and surface coating, the analysis and control of compressed-air quality is a crucial factor, according to Beko. The network-compatible Metpoint OCV offers constant monitoring down to the range of a thousandth mg/m3 and features a touch-screen display and 24/7 pr...
