Diaphragm Pump

The 1410 Series DC miniature diaphragm pump from Thomas Division (Sheboygan, WI) measures 3.3 × 1.2 × 2.1" and is designed so that a full range of motor options, and several design configurations, can be used, depending on the life requirements and specifications of the application. Designed for applications requiring high performance in a compact package, the 1410 Series features a low sound level, is lightweight (0.4 lbs/180g), and is EMC suppressionqualified to EN55011-B on some designs. Maximum flow is 4.3 lpm, with a maximum pressure of 27.5 psig/1.9 bar, and a maximum vacuum of 22.0 in.Hg.

Slotless Motor

Koford Engineering LLC (Winchester, OH) has introduced a short-length 28 mm (1.102") diameter slotless 2-pole motor with an axial length of 23.9 mm (.941"). The motor is designed for applications with limited available axial length, and features winding from 4,428 rpm up to 14,952 rpm. Custom winds to meet special applications are also available. An ambient temperature range from -73 to 100 ºC and a maximum internal temperature of 150 ºC allow a wide range of applications such as blowers, pumps, beam choppers, and scanners. The slotless design offers no cog, resulting in smooth rotation. Matching sensorless drives are also available.

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.

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.
