This is the instruction manual for Endevco® Model 727 series products, which introduces the features and usage methods of the products.
This manual provides technical details for the Endevco 727 series of undamped piezoresistive accelerometers, designed for shock measurements in mobile consumer electronics. It covers handling precautions, mounting procedures, cable handling, and electrical considerations. The accelerometers are shipped with ESD-safe packaging and require careful handling to avoid damage. Calibration certificates and product specification sheets are included or available upon request.
Mounting requires a smooth, clean surface with specific roughness and flatness tolerances. Wax mounting is recommended, and cable strain relief is critical to prevent damage. Electrical excitation voltage must be specified at order time, with 10.000 Vdc as the standard. Longer cables require special handling to avoid signal attenuation and frequency loss.
| Excitation Voltage | 10.000±0.005 Vdc (max 12 Vdc) |
|---|---|
| Mounting Surface Roughness | 32 micro inches rms or better |
| Input/Output Resistance | 650 Ω ± 300 Ω |
The mounting surface should have a surface roughness of 32 micro inches rms or better.
The standard excitation voltage is 10.000±0.005 Vdc, unless otherwise specified at order time.
