Title:
PRESSURE SENSOR
Document Type and Number:
Japanese Patent JPH04370729
Kind Code:
A
Abstract:
PURPOSE:To reduce the influence of an out-side noise and transmit an exact pressure value signal without any relation to the length of a transmission route on signal transmission. CONSTITUTION:In regard to the pressure sensor, an AD conversion circuit 8 for converting the analog output of the pressure sensor part 1 into a digital signal, CPU 9 for calculating a pressure value from the digital signal and a microcomputer 7 having a serial input and output circuit 10 for converting the pressure value into a serial transmission signal are equipped. The pressure value is serially transmitted to a transmission route 6 by the use of a digital form.
