Introduction

Capacitive accelerometers are based on proven micro-electro-mechanical systems (MEMS) technology. These capacitive accelerometers are reliable and long-term stable. They have a DC response. The advantage of these sensors is their outstanding temperature stability, high frequency response and low noise-high resolution. These sensors have a reliable aluminum housing with IP68 protection class.
Dynalabs 3000SI series triaxial accelerometers provide an ultra-low noise performance from 0.7 to 1.2 μg/√Hz. These accelerometers provide excellent bias and scale factor stability and a wide frequency range (±3dB) from 550 Hz to 700 Hz.
DYN-C-3000-SI sensors offer the following options;

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

Operation and Installation

General
The general sensor connector configuration is given below; Cable Code/Pin Configuration:

• Red : V + Power supply voltage +6 to +40 VDC
• Black : Ground Power GND
• X-Axis: Yellow : Signal (+) Positive, analog output voltage signal for differential mode
• Purple : Signal (-) Negative, analog output voltage signal for differential mode
• Y-Axis: Blue : Signal (+) Positive, analog output voltage signal for differential mode
• Green : Signal (-) Negative, analog output voltage signal for differential mode
• Z-Axis: White : Signal (+) Positive, analog output voltage signal for differential mode
• Orange : Signal (-) Negative, analog output voltage signal for differential mode

WARNING

• Never connect the power supply and/or the power ground to yellow, purple, blue, green, white and/or orange 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 – gravity directions, providing a value of ±1 g. The measurement should be made as follows;
• When the acceleration value of 3000SI series sensors is entered into the data acquisition system, the sensor shows +1 g with the effect of gravity, which is in the direction of the axis to be calibrated.
• 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 10% tolerance. Sensor catalog sensitivity values are given in Table 1.
