Component Specifications

Definition
A MEMS (Micro-Electro-Mechanical Systems) sensing element is a microscale device that integrates mechanical elements, sensors, actuators, and electronics on a silicon substrate. In grade sensors, it detects minute changes in inclination, acceleration, or vibration to determine surface angles or slopes with high precision.
Working Principle
Operates based on capacitive, piezoresistive, or piezoelectric transduction mechanisms where physical displacement of microscopic structures (beams, diaphragms, or proof masses) due to inclination changes alters electrical signals (capacitance, resistance, or voltage), which are processed to calculate grade angles.
Materials
Silicon (monocrystalline), silicon dioxide (SiO2), silicon nitride (Si3N4), polysilicon, aluminum or gold for electrodes, with protective polymer coatings (e.g., parylene) for environmental resistance.
Technical Parameters
  • Accuracy ±0.1 degrees
  • Resolution 0.01 degrees
  • Output Signal Analog voltage, digital I2C/SPI
  • Supply Voltage 3.3V or 5V DC
  • Shock Resistance >5000 g
  • Measurement Range ±90 degrees
  • Frequency Response 0-100 Hz

Standards
ISO 16063-21, IEC 60747-14-1, DIN EN 60068-2-6

Frequently Asked Questions

What is the typical lifespan of a MEMS sensing element in a grade sensor?

Typically 10-15 years under normal operating conditions, depending on environmental factors like temperature extremes, vibration, and contamination.

How does a MEMS sensing element differ from traditional inclinometers?

MEMS elements are significantly smaller, more cost-effective, and offer higher shock resistance and faster response times due to their integrated micro-scale design, unlike bulkier mechanical or optical inclinometers.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
