This document introduces the features and usage instructions of Model 7264B Low Mass Miniature Piezoresistive Accelerometer
The document provides instructions for the Model 7264B, a low mass, miniature piezoresistive accelerometer. It details the materials supplied with the unit, including specific Allen wrenches, washers, and screws, and outlines critical precautions to avoid damage during handling and mounting, such as avoiding drops and controlling torque.
| Mounting Torque (Recommended) | 2.6 in-lbf (0.29 N-m) |
|---|---|
| Mounting Torque (Maximum) | 3.0 in-lbf (0.34 N-m) |
| Minimum Insulation Resistance | 100 megohms |
| Impedance Tolerance | ±25% of calibrated value |
| Recommended Surface Roughness | 32 micro inch rms |
The recommended mounting torque is 2.6 in-lbf (0.29 N-m), which is roughly equivalent to finger tight with the supplied wrench.
Sensitivity and ZMO calibration should be performed at 6 to 12 month intervals, depending on usage.
Dirty units may be wiped clean using a damp cloth and a solvent such as acetone, but should not be soaked or immersed.
