This manual provides detailed instructions on the installation, operation, and maintenance of the Endevco 7264c Vibration Sensor.
This manual 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 torque specifications and the use of supplied materials like Allen wrenches and washers.
The document outlines a 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 every 6 to 12 months.
| 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 do not soak or immerse it.
