The Spindler ICP vibration sensor from the Industrial Monitoring Instrumentation Div. of PCB Piezotronics Inc., Depew, N.Y., features a small size and swivel mounting for out-of-the-way installations. Durable, stainless-steel housing with sealed, armored cables withstands the rigors of cutting fluids and flying metal chips. Integrated electronic filtering prevents saturation problems, yet still responds to high-frequency vibrations associated with spindle bearings. The sensor is recommended for predictive maintenance and condition monitoring, as well as wear detection for maintaining machined-part quality.
