This file is the installation instructions of the IM7264B piezoresistive accelerometer
This manual provides instructions for the Endevco Model 7264B, a low mass, miniature piezoresistive accelerometer. It details necessary precautions to avoid damage during handling and mounting, including torque specifications and the use of supplied materials like Allen wrenches and washers. The document outlines a check-out procedure to verify proper operation upon receipt, involving impedance, insulation resistance, and zero measurand output tests.
| 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), with a maximum of 3.0 in-lbf (0.34 N-m).
Sensitivity and ZMO calibration should be performed at 6 to 12 month intervals, depending on usage.
All insulation resistance readings should be a minimum of 100 megohms.
