High stability pressure sensor

High stability pressure sensor with UART output

SP38D-U use high stability monosilicon technology with built-in temperature compensation, intergrated high performance dual-channels ASIC with 24bit adc.

Calibration for zero and sensitivity of second- order temperature drift and third-order nonlinear to improve the temperature performance of the sensor. It's a comprehensive digital and intelligent sensor with UART output. High overload and high static pressure can up to 40MPa. SP38D is suitable for all kinds of harsh environment, the working temperature is - 40~85°C. It also has the characteristics of high precision, high stability and strong output signal.
