Title:
SENSOR OUTPUT TRAN APPARATUS
Document Type and Number:
WIPO Patent Application WO/2001/096815
Kind Code:
A1
Abstract:
The pulses outputtied in a predetermined time period (T1) from a second oscillator (7) for outputting a pulse at a constant oscillatory frequency independently of pressure are counted to correct the change in the oscillatory frequency of a first oscillator (5) with the temperature on the basis of the counted. Then, the pulses within a constant time period of the first oscillator (5) the oscillatory frequency of which changes with pressure is measured to determine the pressure. By thus determining the pressure precisely independently of the temperature, the pressure can be outputted.
