The SP124104 sensor operates by converting pressure into an electrical signal. The internal sensing element consists of a piezoresistive bridge that changes resistance in response to applied pressure. The output voltage is proportional to this change in resistance, providing a direct measure of the pressure. The sensor is calibrated and temperature-compensated to ensure accuracy over a wide range of operating conditions. Detailed specifications regarding pressure range, accuracy, and temperature compensation can be found in the product datasheet.
