Abstract
The invention provides a composite analog temperature detector for a bimetallic temperature switch, which is characterized in that the temperature detector can output different resistance signals according to the short circuit or broken circuit of the bimetallic temperature switch upon heating, therefore improving the temperature detecting range of the bimetallic temperature switch. The composite analog temperature detector realizes the function by a plurality of technical proposals: a composite analog temperature detector for a bimetallic temperature switch comprises a bimetallic temperature switch, a protection casing, a thermal resistance R, a connecting conductor and a sealed body; wherein, the bimetallic temperature switch comprises a bimetallic strip, a plurality of contacts and a plurality of contactors. The composite analog temperature detector is characterized in that the bimetallic temperature switch is connected in series or parallel with the thermal resistance R and thus can continue to send the signals of resistance changes after the switch motion of the bimetallic temperature switch.
Description
Technical field
The present invention relates to fire alarm installation, a kind of composite analogy amount temperature-sensitive detector for thermometal temperature switch.
Background technology
