IM7264C instruction manual
This document provides instructions for the Endevco Model 7264C, a low mass, miniature piezoresistive accelerometer. It details necessary precautions to avoid damage during handling and mounting, including specific torque limits and the use of supplied materials like Allen wrenches and washers.
The manual outlines a check-out procedure for verifying proper operation upon receipt, including impedance, insulation resistance, and zero measurand output tests. It also describes the mounting process, emphasizing surface cleanliness and proper screw installation, and recommends recalibration intervals of 6 to 12 months.
| Product Type | 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 |
Sensitivity and ZMO calibration should be performed at 6 to 12 month intervals, depending on usage.
The maximum recommended mounting torque is 3.0 in-lbf (0.34 N-m).
Dirty units may be wiped clean using a damp cloth and a solvent such as acetone, but should not be soaked.
