Title:
PRESSURE GAUGE
Document Type and Number:
Japanese Patent JP2004226073
Kind Code:
A
Abstract:
To provide a simple, inexpensive, and highly precise electronic analog display type pressure gauge that is reduced in the number of mechanical elements as compared with the mechanical analog display type pressure gauge.
In this pressure gauge, an electronic sensor which detects the pressure of a fluid based on an electric variation caused by a reversible strain change, an amplifier which amplifies the electric variation of the sensor, a comparator which compares the output of the amplifier, and a display element are mounted of a board. This pressure gauge indicates pressures by analog display.
