gearless temperature gauge
A pressure gauge comprising a diaphragm, a cylinder seat, and a driving helix movable up or down to constitute the operating elements. A rotary shaft with a pin fixed thereon rotates clockwise or counterclockwise responsive to the movement of the diaphragm. The rotary shaft will return to its initial position when the pressure on the diaphragm is removed by the restoring force of a helical spring.
