Abstract
A measuring gauge used for measuring and analyzing a physical value includes a measuring element for capturing the physical value, whereby the measuring element moves according to the physical value, a movement that moves a pointer in relation to the motion of the measuring element in a pointer plane around an axis of rotation of the pointer, whereby an additional indicator irreversibly displays the excess beyond a threshold value.
Claims10
Measuring gauge for measuring and displaying a physical value, comprising
- a pivoting, pointer shaft and a pointer fastened to the pointer shaft,
- a pointer drive by means of which the pointer shaft can be moved from a starting position in relation to the value of the measured value,
- an actuator that is fastened indirectly or directly to the pointer shaft and participates in the rotation,
- an indicator element arranged in a mobile manner,
- whereby the actuator can come into contact with the indicator element when the pointer shaft is rotated from its starting position and carries along or triggers the indicator element,
- wherein the indicator element is arranged so that is carried along or triggered by the actuator before or when reaching a pointer shaft position that corresponds to a set maximum value of the measured value and in that the contact with the actuator is lost when or after this maximum pointer shaft position is reached and moves into an end position in which the indicator element is fixed, and
- a pretension element that acts on the indicator element and exerts a spring-elastic force on it, which moves the indicator element to its end position and maintains it there.

- wherein the indicator element comprises a pointer shank and an additional pointer fastened to it whereby the pointer shank is arranged in a pivoting manner in a bushing,
- wherein the pointer shank is arranged in an axially displaceable manner in the bushing whereby the bushing comprises a latch recess into which the additional pointer moves while simultaneously moving in axial direction of the bearing shank and is fixed in this manner when the maximum pointer shaft position is reached, and
- wherein the axis of rotation of the bearing shank runs parallel to and at a distance from the axis of rotation of the pointer shaft.
