Digital Accelerometers

API Technologies Corp. (Orlando, FL), has announced a high-g digital accelerometer from its Sensors line of inertial measurement products. Measuring up to 500 g, this accelerometer is used for shock detection. Available in ±500 g and ±250 g versions, the unit comes in single-axis, dual-axis, and triaxial models. The accelerometers are user-configurable and contain the accelerometer(s), temperature sensor, signal processor, three analog outputs, and an RS-485 interface that connects directly to the user’s PC. The accelerometers come fully calibrated with calibration data stored inside the sensor. Ruggedized construction makes them suitable for harsh environments. Additional features include linearity over a wide temperature range, power and connector kits for set-up, and data analysis tools.

Ball Bearing

Bishop-Wisecarver Corp. (Pittsburg, CA) has announced The Radial Wheel, a single-row, deep-groove ball bearing designed for applications with specified radial loading conditions. The wheel enables reliable motion in environments exposed to debris such as sawdust or grit. The bearings make it possible to convey heavy loads without additional capabilities unnecessary to the application requirements. The 90-degree vee-groove bearings work in finished products like sliding wall panels and motorized doors and windows.

Vibration Control System

Crystal Instruments Corp. (Santa Clara, CA) has introduced the Spider-81, a modular, distributed, scalable vibration control system with centralized DSP architecture and operation via PC, WiFi-enabled PDA, or iPad. It directly integrates time-synchronized Ethernet connectivity with an embedded DSP centralized architecture. Its patented dual A/D design enables it to achieve a 130-dB input dynamic range. Each measurement channel can detect signals ranging from 6 μV to 20V, with a design that eliminates the need for the input range or gain settings found on traditional controllers.
