Gauge having adjustable activating means

A gauge having adjustable activating means for activating an alarm comprising a movement case including a front open portion and a back portion, a gauge movement responsive to a sensed condition located inside the case and driving a rotary gauge shaft and an indicator needle indicating said sensed condition on a scale dial, wherein the adjustable activating means comprising:

• a plurality of at least two rotating adjusting guides having a lever portion, each adjusting guide mounted on the rotary shaft one before the other and freely rotating on the shaft, said lever portion allowing to easily rotate an adjusting guide from the front of the movement case, and said rotating adjusting guides defining one or more thresholds;
• sensor means connected to an alarm, said sensor means attached to each rotating adjusting guide, for activating said alarm;
• securing means for each adjusting guide for applying a pressure to an adjusting guide but not restricting the rotation thereof in order to secure an adjusting guide in a predetermined position;
• bump means for each rotating adjusting guide, said bump means restricting the rotation of each adjusting guide thus defining a limited rotation arc which is representative of a predetermined range of a scale dial;
• activating means for activating said alarm coupled to the rotary gauge shaft and located close to the plurality of adjusting guides, said activating means rotating together with the rotary gauge shaft and defining a circular path as the rotary gauge shaft rotates until the activating means make contact with one of the sensor means which send a signal to the alarm;
• and
• said scale dial attached to the movement case at its front open portion, and having a central perforation to allow the pass of an end of the rotary gauge shaft and having an semicircular slot allowing the pass of the lever portions of the plurality of adjusting guides, said semicircular slot defining a “scale adjusting zone” and said scale dial representing different values of a predetermined scale.
