Adjustable set point signalling gauge |
摘要 |
An adjustable signalling gauge may utilize a non-captivating, magnetically actuated switch element which is mounted in an influence zone of the path of a magnet carried by an indicating pointer of a gauge. The gauge may be easily adjusted by an indirect adjustment mechanism. The adjustment may be by a reducing gear. Indirect adjustment effectively allows a reduction in the torque required to change the switching threshold.
