For increasing the precision of measuring, described sensor adopts infrared ray sensor.
The principle of work of manometer dish is as follows: when pressure, pass to the pressure sensing spring by the hollow channel of screw thread holder, the pressure sensing spring band bar that is dynamically connected, connecting link drives an end of S shape drive link, and S shape drive link drives the gear of the other end around the turning axle rotation at its middle part, the gear driven central driver gear rotates, central driver gear driven gear axle rotates, and gear shaft drives pointer and rotates, and shows pressure data.
The utlity model has following advantage:
1, because the wiring board of sensor by being bolted on the screw thread holder, has increased stability of structure; Reduce the horizontal stand of screw thread holder, increased measuring stability.
2,, increased the precision of measuring because sensing point is established four.
3, owing to saved magnet, increased term of life.
4, set up horizontal plate with the pointer coaxial rotation, increased the precision of measuring.
5, change into the quarter butt that can rotate around the middle part by original arch connecting link and constitute, increased the precision of measuring by two-section.
