At the exhibition, LEEG will present a range of its core products, with a key focus on its monosilicon sensors. These sensors will demonstrate advanced technological applications in high-precision pressure, differential pressure, and multi-variable measurement. Another highlight will be the sanitary pressure transmitters, designed for high-purity applications in industries such as food, pharmaceuticals, and bio-fermentation. Additionally, LEEG will feature its multi-variable transmitter series, showcasing its integrated capabilities for simultaneous measurement of differential pressure, pressure, and temperature, as well as flow calculation in comprehensive monitoring and control scenarios. Through this diverse product lineup, LEEG aims to present its latest technological strengths and solutions in high-performance sensing and intelligent measurement and control.
Monosilicon Pressure Sensor
The LEEG Monosilicon pressure sensor utilizes a modular design, achieving high sensitivity, suitability for mass production, and allowing for fast modular replacement/customization. When combined with an ASIC, it enables digital output. It features an ultra-high purity (9N grade) Si-Si bonded MEMS silicon wafer with an extremely low coefficient of thermal expansion (CTE) and a unique diamond-suspended sensor structure, ensuring long-term stability of ±0.1% SPAN/10 years. The high-elasticity diaphragm material, with an elastic modulus of 200 GPa, guarantees long-term repeatable performance.
LEEG Monosilicon Pressure/Differential Pressure Sensors
These sensors employ a unique structural design where the high-precision monocrystalline silicon sensing element is mounted on the top of the metal body, away from the medium contact surface. This design fundamentally provides mechanical and thermal isolation, effectively reducing the impact of temperature gradients, vibration, and medium corrosion on measurement. The sensor leads are integrated with the metal base through glass frit sealing, creating high-strength electrical insulation and reliable long-term sealing. This ensures stable electrical performance and long-term reliability even in harsh environments involving high temperatures, high pressures, or strong corrosives, making them particularly suitable for chemical, petrochemical, and other industrial process controls with demanding mechanical loads.
This sensor integrates differential pressure, pressure, and temperature sensing elements on a single chip platform, enabling simultaneous measurement and real-time compensation of multiple parameters. It serves as the core functional module for integrated differential pressure flow transmitters. This design not only enhances measurement accuracy and dynamic response speed but also simplifies system architecture, reduces installation space, and minimizes maintenance. It offers a high-stability, high-reliability total solution for multi-variable process control applications such as steam flow, liquid flow, and energy measurement.
LEEG will introduce two types of monosilicon pressure sensor element products: an analog uncompensated type that outputs a raw signal, allowing customers to design their own circuitry for secondary calibration; and an intelligent type with built-in digital compensation, featuring factory-calibrated temperature and zero-point compensation for direct, stable digital signal output. In addition to standard threaded process connections, LEEG can provide customized designs to meet diverse industrial application needs and specific installation requirements.
