The Secret Behind AUTO INSTRUMENT’s Accurate and Stable Sensors

At Yantai Auto Instrument Manufacturing Co., Ltd., we understand that precision is the cornerstone of quality in instrumentation. For over 30 years, our commitment to excellence has driven us to refine every aspect of our manufacturing process—including the vital oil-filling system for sensors.

Our proprietary oil-filling process ensures that each sensor achieves unparalleled accuracy and stability. By leveraging advanced equipment, we maintain strict control over every step, from filling to sealing. This precision eliminates air gaps and inconsistencies, resulting in sensors that perform reliably even in the most demanding environments.

Our sensors, including single-flange differential pressure transmitters and dual-flange level transmitters, benefit directly from our oil-filling technology. The accurate oil distribution within the sensor chambers ensures their ability to handle extreme conditions, such as high pressure, high temperature, and corrosive media, without compromising performance.

Quality is further guaranteed through our cutting-edge detection systems. Each sensor undergoes rigorous inspection during and after the oil-filling process to detect even the slightest imperfections. This ensures that every product meets the high standards our clients expect, with consistent performance over its lifecycle.

Years of experience have taught us that the details matter. That’s why our oil-filling process has been continually optimized to enhance the durability and accuracy of our sensors. Whether used in chemical processing, oil and gas, or power generation, our sensors deliver consistent results you can rely on.
