Micro Sensor Co., Ltd. has been around for more than 50 years and is the first company in China to develop pressure sensors and transmitters designed around piezoresistive measurement principles. Their products are top-notch and available worldwide.

Originating from Baoji Qinling Transistor Factory (located in Shaanxi Province, China), MicroSensor, developed diffused silicon pressure sensors in 1971 and in 1993 established the Sino-US joint Micro Sensor Company which later led to their new name, Micro Sensor Co., Ltd. Over the years, Micro Sensor Co., Ltd. has focused its strengths on technical development, mass production, and technical services in industrial and control areas to cater to the needs of more clients worldwide. Despite their focus, they have continued to increase their pressure sensors’ production and accuracy, which leverages the company’s more than 50 years of experience.

With a history of over 50 years and over 500 employees across its branches in Xi’an, Shanghai, and Germany, the company is the first to self-design and produce piezoresistive pressure sensors in China. Their years of research and manufacturing experience goes into providing cutting-edge pressure sensors and transmitters for use across industries. Their products, including pressure transmitters, level transmitters, flowmeters and pressure sensors have become world-class and are used across industries as sensing and measuring products.

“MicroSensor provides customers with sensors and transmitters for pressure and liquid level measurement of fluid media (gas, liquid), as well as instruments such as temperature sensors, flow meters and IoT terminals. We are a high-quality and reliable supplier of sensors and monitoring instruments,” said the company’s spokesperson.

Having increased its array of available pressure sensors offered, Micro Sensor Co., Ltd.’s products are now available in over 100 countries and regions worldwide. They also serve more than 20,000 customers with an annual turnover of over $45 million to show. Their products, including the basic piezoresistive pressure sensors, small-size pressure sensors, and anti-corrosive pressure sensors, are used mainly in industries like oil and gas, renewable energy, industrial gases, water and sewage, marine vessels, HVAC, hydraulic and pneumatic equipment, industrial automation, food and medical, and industrial Internet of Things.

At present, Micro Sensor Co., Ltd. has four major manufacturing plants of sensors, transmitters, flow meters, and the Internet of Things. The manufacturer also has a 100,000-level purification workshop, a self-developed test and calibration system, fully automatic processing equipment, and a professional standard supply platform to make its work easier and facilitate high quality manufacturing practices. Leveraging the resources at its disposal, Micro Sensor Co., Ltd. can provide millions-level, large scale and fast batch supply of products like diffused silicon piezoresistive pressure sensing element, pressure sensors/transmitters, differential pressure sensors/transmitters, liquid level transmitters, temperature transmitters, pressure/temperature/liquid level switches, electromagnetic flowmeters, IoT wireless monitoring terminals and other instruments.

All products supplied by the company complies with the ISO9001 quality management system, ISO14001 environmental management system, ISO45001 occupational health and safety management system, and ISO/IEC 80079-34 explosion-proof quality management system. Micro Sensor Co., Ltd. has 103 patent, professional certificated of CE, RoHS, UL, CB, Ex, ATEX, CCS, MA, DNV·GL, SON, and other professional certifications totaling 121 items.
