MicroSensor - Model MPM281 -High Stable Pressure Sensor
The MPM281 series offers a high-stable piezoresistive pressure sensor tailored for precision measurements across various industrial and medical fields. This OEM pressure element features a robust 316L stainless steel construction, ensuring durability in harsh environments. Utilizing advanced diffused silicon technology, the sensor provides exceptional sensitivity and enables precise pressure-to-electrical signal conversion. With its broad temperature compensation range from -10? to 80?, the MPM281 is apt for conditions with significant temperature fluctuations, such as outdoor oil field applications. Its long-term stability is assured with an accuracy of ±0.2% FS/year, making it ideal for use in petrochemical monitoring, inkjet printing, and flow compensation. Its design supports multi-medium measurements, catering to the demands of process automation and medical equipment.
The MPM281 high stable pressure sensor is an isolated, precision-compensated OEM piezoresistive pressure measurement element. Sensitive components use patented high-stability diffused silicon components. The product is packaged in a 316L all-stainless steel structure with an outer diameter of ?19mm. After precision trimming, the temperature compensation and zero point deviation correction of the imported chips are carried out in a wide temperature range through the thick film circuit. The wide temperature compensation range can reach -10?~80?.
MPM281 piezoresistive pressure sensor is used in various measuring instruments to realize the precise conversion of pressure to electrical signals. It can also be used in petrochemical pipeline monitoring, inkjet printer pressure monitoring, flowmeter pressure compensation, medical equipment and other fields. It is also suitable for industrial automation fields where the site temperature changes greatly, such as oil field sites exposed to the outdoors for a long time.
