Introduction

The piezoresistive accelerometers are based on micro-electro-mechanical systems (MEMS) technology. Piezoresistive accelerometers are used for high impact applications in automotive industry such as crash testing. 4000 Series Dynalabs uniaxial accelerometers feature a wide frequency range up to 5,000 Hz and excellent shock resistance up to 10,000 g. 4000 series accelerometers are lightweight. They have reliable aluminum housing with IP68 protection classs. These sensors have integrated cable with configurable length and connection options.
DYN-P-4000 sensors offer the following options;

• Custom Cable Length (5m standard cable)
• Custom Housing Material
• Custom Connector
• Base plate

WARNING
Never connect the power supply and/or the power ground to yellow, and/or blue cables.
Never connect the power supply to the power ground. Always use a clean power source and check the voltage range.

Sensor Static Calibration Verification

Using gravity, voltage values are measured in the + and – directions, providing a value of 1 g.
The measurement should be made as follows;
When the sensitivity value of 4000 series sensors is used with the data acquisition system, the sensor shows +1 g with the effect of gravity in the direction of the arrow sign.

When the sensor is positioned in the opposite direction to the axis to be calibrated, the arrow shows -1g as shown below under the effect of gravity.
Using gravity, the voltage values that provide 1 g in the + and – directions are measured and compared with the catalog value. The calibration value should be close to the catalog value with a 10% tolerance. Sensor catalog sensitivity values are given in Table 1.
