We offer pressure sensors based on monosilicon piezoresistive technology, including digital compensated pressure sensors and analog uncompensated models. Additionally, we provide ODM or OEM customization projects to meet your diverse needs.
Digital Compensated Pressure Sensor
Our digital compensated pressure sensor features fully automated digital compensation across the entire temperature range, including zero-point drift compensation, temperature drift compensation, nonlinearity compensation, and sensitivity correction. It offers multiple output options, such as I²C, SPI, and RS485. The stable analog signal processed by the MCU facilitates integration into industrial systems and smart devices like PLC and DCS. The pressure sensor ensures excellent long-term stability with an accuracy of 0.075% F.S. (0.05% F.S. optional) and minimal long-term drift, making it suitable for long-term continuous operation. It is easy to use, requiring no external calibration circuits, and allows direct data reading, significantly reducing debugging and calibration costs.
SP38H-UART Interface Monosilicon Pressure Sensor
The SP38H-UART monosilicon pressure sensor features a triple-diaphragm overload structure, built-in temperature-sensitive components, and a dual-channel 24-bit ADC. It withstands high overload and high static pressure, with static pressure resistance up to 40 MPa. Suitable for various harsh environments, its operating temperature range spans -40 to 85°C. It is easy to encapsulate and interface with a standard UART bus. Widely used in industrial automation, gas measurement, hydraulic and pneumatic equipment, servo valves and drives, chemicals and chemical industries, medical instruments, and other fields requiring pressure or differential pressure measurement. In any scenario demanding high precision, consistency, and stability, the SP38H-UART interface monosilicon pressure sensor is the preferred choice.
Customized Pressure Sensor Design
At LEEG Instruments, we provide comprehensive pressure sensor customization services for global users. Customizable aspects include pressure types such as differential pressure, gauge pressure, and absolute pressure; outputs like mV, I2C, SPI, and UART; and diaphragm and housing materials such as 316L stainless steel, Hastelloy C, tantalum, titanium, or gold-plated processes. From electrical output and pressure type to overall performance, materials, and process interfaces, every critical configuration can be tailored to your application. You can submit your requirements or provide drawings, and we will help you create a reliable, precise, and long-term stable sensing solution.
