Introduction

Capacitive accelerometers are based on proven micro-electro-mechanical systems (MEMS) technology. These capacitive accelerometers are reliable and long-term stable. These sensors are Differential Ended type DC response sensors. The advantages of these sensors are their outstanding temperature stability, external noise immunity and their lightweight. These sensors feature standard reliable aluminum housing with protection class IP68. Steel housing is also possible.
Dynalabs LN accelerometers provide Low noise – high resolution with an outstanding noise performance from 9 to 680 μg/√Hz. These accelerometers provide a wide frequency range (±5%) from 250 Hz to 1,500 Hz.

DYN-C-1000-LN sensors offer the following options;

• Custom Cable Length
• Custom Housing Material
• Custom Connector
• Base plate

Outline Drawing
The dimensional properties of DYN-C-1000-LN sensors are given below ;

Operation and Installation

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

• Red : V + Power supply voltage +5 to +20 VDC
• Black : Ground Power GND
• X : Yellow : Signal(+) Positive, analog output voltage signal for differential mode.
  Blue : Signal(-) Negative, analog output voltage signal for differential mode.

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 – gravity directions, providing a value of ±1 g. The measurement should be made as follows;

• When the sensitivity value of 1000LN 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 in the opposite direction of the arrow, it shows -1 g with 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.
