This document describes how to use the 7264C type vibration sensor
The Endevco IM7264C is a low mass, miniature piezoresistive accelerometer. The manual provides instructions for handling the unit to avoid damage, including precautions against dropping or striking it. It details the materials supplied with the unit, such as Allen wrenches and screws, and specifies the recommended mounting torque of 2.6 in-lbf (0.29 N-m) with a maximum of 3.0 in-lbf (0.34 N-m).
| 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 |
| Impedance Tolerance | ±25% of calibrated value |
| Surface Roughness | 32 microinch 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.
