摘要

An item of measuring equipment, eg a thermometer, manometer, has a unit mounted [2] that supports a fork [5] that fits around the instrument pointer spindle [4]. The fork has a magnet [9] and is pivot mounted. At a specific position a sensor [10] signals an electronic circuit to indicate a specific measured value has been reached.
