The Model 7264C is a low mass, miniature piezoresistive accelerometer produced by Endevco.
The Endevco Model 7264C is a low mass, miniature piezoresistive accelerometer. The manual provides specific precautions for handling and mounting the unit to avoid damage, including warnings against dropping the unit and over-torquing the mounting screws. It lists the materials supplied with the unit, such as Allen wrenches and socket head cap screws, and details the correct installation torque of 2.6 in-lbf (0.29 N-m) with a maximum of 3.0 in-lbf (0.34 N-m).
The document outlines a check-out procedure for verifying proper operation upon receipt, including impedance tests, insulation resistance checks, and zero measurand output verification. It also describes the mounting process, emphasizing the need for a clean surface and proper cable management, and provides guidelines for recalibration intervals and cleaning the unit.
