TAUT WIRE SENSOR

摘要

A taut wire sensor (10) includes an actuator (26) that is movably coupled to a housing (16). The actuator (26) includes a taut wire terminal (15). The actuator (26) has two contacts (11, 12) that are maintained in a spaced apart orientation by the mating of parts, which are held in place by spring (25) element. The actuator (26) deforms when force is applied to the taut wire (15) terminal of the sensor (10). When the actuator (26) deforms, an electrical connection is made between the two contacts (11, 12) to produce an alarm indication by the sensor (10). The orientation of the actuator (26) is maintained by the mating of parts which are also held by a spring element (25). One of the contacts in the actuator (26) is a flexible contact pin (11) that is adapted to bend when high force is applied to the taut wire terminal (15). The sensor housing (16) also includes a movement limiter (34) that overcomes a weakness in prior sensors which employ compensating flowable materials (13) to adjust sensor position.
