IM7264B instruction manual, which introduces the characteristics and usage of the 7264B model sensor
This manual provides detailed instructions for installing, testing, and maintaining the Endevco 7264B piezoresistive accelerometer. It includes precautions for handling, mounting torque specifications, and procedures for initial check-out using impedance, insulation resistance, and zero measurand output tests. The document also covers recalibration intervals and cleaning guidelines to ensure proper performance and longevity of the unit.
Mounting requires specific tools and techniques to avoid damage, including using the supplied Allen wrench and washers with a torque of 2.6 in-lbf (0.29 N-m) maximum. Cable management and proper handling during installation are emphasized to prevent strain or damage. Recalibration is recommended every 6 to 12 months depending on usage, with contact information provided for Endevco support.
The recommended mounting torque is 2.6 in-lbf (0.29 N-m), with a maximum of 3.0 in-lbf (0.34 N-m).
Dirty units may be wiped clean using a damp cloth and a solvent such as acetone. DO NOT SOAK OR IMMERSE the unit in any solvent or water.
If any of these initial checks do not give proper readings, indicating a possible malfunction, and the reason for the erroneous reading cannot be found, contact Endevco.
