定义
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.
工作原理
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.
材料
Silicon (monocrystalline)silicon dioxide (SiO2)silicon nitride (Si3N4)polysiliconaluminum or gold for electrodeswith protective polymer coatings (e.g.parylene) for environmental resistance.
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

常见问题

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.
