Title:
PRESSURE DETECTING DEVICE
Document Type and Number:
Japanese Patent JPH0815070
Kind Code:
A
Abstract:
PURPOSE: To provide a pressure detecting device by which temperature compensation can be made when the device detects a pressure.
CONSTITUTION: When an atmospheric pressure value ATM is measured based on the output of a pressure sensor 10, a CPU 1 instructs a sensor driving circuit 9 to drive a magnetic sensor 11 with a constant current and temperature data are prepared from the output signal of the sensor 11 driven with the constant current by means of the circuit 9 through a temperature conversion table. Then temperature compensation is made on the atmospheric pressure value ATM based on the temperature data. Therefore, the temperature compensation can be performed at the pressure detecting time by means of the magnetic detecting means.
