This manual is for the IM7264C accelerometer installation
This document provides instructions for the Model 7264C, 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 manual outlines a three-step check-out procedure for verifying proper operation upon receipt, including impedance, insulation resistance, and zero measurand output tests. It also covers mounting techniques, cable management, and guidelines for recalibration intervals.
| Type | Piezoresistive Accelerometer |
|---|---|
| Mounting Torque (Recommended) | 2.6 in-lbf (0.29 N-m) |
| Mounting Torque (Maximum) | 3.0 in-lbf (0.34 N-m) |
| Insulation Resistance | 100 megohms minimum |
| Surface Roughness | 32 microinch rms |
The specified 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.
Yes, dirty units can be wiped clean with a damp cloth and a solvent such as acetone, but the unit must not be soaked or immersed.
