Micro Sensor Co., Ltd.
About
Micro Sensor Co., Ltd. is a Chinese manufacturer founded in 1993 in Baoji, Shaanxi Province, with over 800 employees and 100-plus R&D engineers. The company produces more than 3 million measurement units annually across four domestic manufacturing facilities and a German subsidiary in Essen, serving 20,000-plus customers in 95 countries and regions. Core technology centers on piezoresistive and monocrystalline silicon pressure sensing, with OEM sensor elements spanning the MPM280 (customized), MPM281 (high-performance), and MPM288 (general-purpose) series covering ranges from 0.2 bar to 1000 bar. Transmitter product lines include the M20 compact series for general industrial use, the MPM483E with LCD/LED display and high EMC protection, the MPM486 HART communicator for process integration, the MPM4730 with RS485/HART digital output and DNV marine approval, and the flagship MDM7000 smart transmitter platform achieving plus or minus 0.05 percent URL accuracy with 100:1 turndown in differential, gauge, and absolute pressure variants. Specialized variants include the MPM280Au gold-plated hydrogen pressure sensor for fuel cell applications and the MDM291 water differential pressure sensor. Flow measurement covers electromagnetic flowmeters (MFE600E series, DN3 through DN2400, with CE and ATEX approval), calorimeters (MFE600H, DN25 through DN400), and insertion-type electromagnetic flowmeters (MFE600C, DN200 through DN1600). Level products encompass submersible, radar, ultrasonic, and magnetostrictive technologies. The company holds 223 patents and over 240 product certifications including CE, ATEX, IECEx, UL, SIL, DNV, ABS, LR, BV, 3A, EHEDG, and RoHS, and offers custom OEM and ODM sensor development.
