Accelerometers

Wilcoxon Research (Gaithersburg, MD) has introduced the 788A accelerometers that feature a sensitivity of 100 mV/g. The accelerometer is a single-axis sensor with an acceleration range of +50 g. High-frequency response measurements up to 10 kHz identify faults and improper machine operation. Typical noise is 4 mg at 100 Hz. The unit operates at temperatures between -50 and 120 °C. Applications include vibration monitoring of fans, motors, pumps, blowers, compressors, chillers, gearboxes, and mixers.
