This manual introduces the use of Model 7264B low mass miniature piezoresistive accelerometer, including assembly and installation.
This manual provides instructions for installing, testing, and maintaining the Endevco 7264B piezoresistive accelerometer. It includes precautions for handling, torque specifications, and procedures for impedance, insulation resistance, and zero measurand output tests. Maintenance guidance covers recalibration intervals and cleaning methods.
The document also details mounting requirements, such as surface roughness and screw torque, and advises against using adhesives or excessive torque. Contact information for Endevco’s Application Engineering is provided for support.
The maximum recommended mounting torque is 3.0 in-lbf (0.34 N-m).
The insulation resistance should be 100 megohms minimum.
The recommended surface roughness is 32 micro inch rms.
The ZMO should be within the data sheet specified limits.
