Microelectromechanical systems (MEMS) is a technology that, in its most general form, can be defined as the miniaturization of mechanical and electromechanical components (i.e., devices and structures) fabricated using micromachining techniques. MEMS technology sensors are low-cost, high-precision inertial sensors that can be used in a variety of industrial applications.
MEMS, or microelectromechanical systems, is a chip-based technology in which the sensor consists of a suspended mass between a pair of capacitive plates. This suspended mass creates a difference in electrical potential when the sensor is tilted. The resulting difference is then measured as a change in capacitance.
Technical characteristics of MEMS technology
① advantage
MEMS technology does have some advantages of its own. modbus tcp gateway MEMS sensors offer convenient functionality and can be used with all other sensor families without any space constraints. Additionally, MEMS utilize very compact micromachine components that are so small that each MEMS sensor fits easily in the palm of your hand. The MEMS sensor has IP67 sealing. This is because the sensor needs to be able to withstand extreme temperatures from -40 to +85C. Most industries that use MEMS sensors operate at extreme temperatures. Also, this seal allows the sensor to be temporarily submerged in shallow water, allowing monitoring of pitch and roll applications both offshore and subsea. Other electrolytic sensors may have higher accuracy, but are generally more temperature sensitive.
Another advantage of these MEMS sensors is their resistance to shock and vibration. MEMS sensors may not be the most durable in shock-absorbing environments, but MEMS inclinometers have a vibration resistance of 10grms at 10-1000Hz, and accelerometers have a shock resistance of 100G. Therefore, these sensors cannot be used in highly shocking scenarios such as military applications, but they can withstand industrial measurement and control, drilling equipment and some geotechnical engineering monitoring.
②Disadvantage
As useful as MEMS sensing technologies are, they do have some limitations. serial to wifi converter Typically, MEMS sensors have a large drift over the entire temperature range. For those without temperature compensation or heating capabilities, this may be of concern. Also, MEMS sensors typically have lower accuracy compared to other traditional and more expensive sensors. Therefore, you should always determine exactly what you need to measure before making a purchase. MEMS sensors are ideal for applications that do not require the highest accuracy, such as industrial automation, platform steering, position control, and pitch and roll measurements. This is why MEMS electrolytic sensors are perfectly suitable for many different fields at low cost.
