This document is the instruction manual for IM7264B Piezoresistive Accelerometer
This manual provides instructions for the Endevco 7264B, a low mass, miniature piezoresistive accelerometer. It details necessary precautions for handling and mounting to avoid damage, including specific torque limits and the use of supplied materials like Allen wrenches and washers. Users are guided on performing initial checks such as impedance, insulation resistance, and zero measurand output tests upon receipt of the unit.
| 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% |
| 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.
