Low Cost, Embeddable Accelerometers Ideal for Continuous Vibration Monitoring in High-Volume and Commercial OEM Applications Highlights n Choice of Standard TO-5 or TO-8 Transistor-Style Packages Choice of Charge Mode Piezoelectric, Voltage Mode ICP®, and 3-Wire Low Power Varieties Mountable via Adhesive or Soldering and Choice of Either Integral Cable or Solder Pin Electrical Connections Variety of Sensitivities to Accommodate a Wide Variety of Applications Broad Bandwidth, High Shock Survivability, Wide Operating Temperature Range, High Resolution, and Large Dynamic Range The Series 660 low cost accelerometers offer an affordable solution for vibration and shock measurements in high-volume and commercial OEM applications. The units are particularly well suited for shock and impact detection of packages or components, as well as bearing and gear mesh vibration measurements in predictive maintenance and condition monitoring requirements. The compact designs may be imbedded into machinery at the OEM level to provide value-added monitoring protection. The units employ field-proven, solid-state, piezoelectric sensing elements for durability and broadband performance. Choose from either charge mode types, which achieve high operating temperatures or voltage mode ICP® types, with built-in signal conditioning microelectronics, for simplified operation and connectivity to data acquisition and vibration monitoring instrumentation. As with all instrumentation from IMI, these sensors are complemented with toll-free applications assistance, 24-hour customer service, and are backed by a Total Customer Satisfaction guarantee.
