SP38M UART Output Multivariable Presure Sensor

Product catalog summary

Product Overview
The SP38M-UART is a high-stability monosilicon pressure sensor featuring built-in differential pressure, temperature sensing elements, and a high-performance dual-channel ASIC with a 24-bit ADC. It is designed to improve temperature performance through calibration for zero and sensitivity of second-order temperature drift and third-order nonlinearity. The sensor offers UART output, high overload, and static pressure resistance up to 40MPa, making it suitable for harsh environments with a working temperature range of -40 to 85°C. It is widely used in process control, flow control, hydraulic and pneumatic equipment, and more.
