Meggitt Sensing Systems’ Endevco model 2226C is a compact and lightweight adhesive-mounted piezoelectric accelerometer designed for the general-purpose vibration testing of smaller structures and objects. With a sensitivity of 2.8 pC/g, the accelerometer features a top-mounted 10-32 receptacle for easy installation within space-constrained environments. Its light weight (2.8 gm) effectively minimizes mass loading. Units are designed to operate over a temperature range of -55 C to 177 C (-67 F to 350 F), while showing output sensitivity stability over time. As a self-generating device, the model requires no external power source for operation. Although signal return is connected to the case, a user may isolate signal ground from the mounting surface by installing the unit with non-conductive adhesive. Its compact design makes the accelerometer a good fit for general in-laboratory vibration testing, small-package testing, engine vibration monitoring, automotive and aerospace component testing, and downhole drilling tool vibration measurements. All Endevco accelerometers are accompanied by a five-year product warranty. In addition, the model 2226C is available at discounted rates as part of the –R replacement sensors program.
