Instruction manual, introducing the characteristics, installation and inspection of the IM7264C accelerometer model
This document is the instruction manual for the Endevco IM7264C, a low mass, miniature piezoresistive accelerometer. It outlines specific precautions for handling and mounting the unit to avoid damage, including warnings against dropping the device and over-torquing the mounting screws. The manual specifies the use of supplied materials, such as Allen wrenches and flat washers, and recommends a mounting torque of 2.6 in-lbf (0.29 N-m) with a maximum of 3.0 in-lbf (0.34 N-m).
The guide details a three-step checkout procedure to be performed upon receipt: an impedance test, an insulation resistance test, and a zero measurand output test. It also provides instructions for proper mounting techniques, including surface preparation, lubrication of screws, and cable management. Finally, it recommends recalibration intervals of 6 to 12 months depending on usage and describes cleaning methods, explicitly warning against soaking the unit or using sharp tools.
| Product Type | low mass, miniature piezoresistive accelerometer |
|---|---|
| Recommended Mounting Torque | 2.6 in-lbf (0.29 N-m) |
| Maximum Mounting Torque | 3.0 in-lbf (0.34 N-m) |
| Minimum Insulation Resistance | 100 megohms |
| Recommended Surface Roughness | 32 microinch 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 readings for insulation resistance should be at least 100 megohms.
