Problems solved by technology

[0003] Due to the strong directivity of the emission direction of the above-mentioned light transmitter, the signal control module can accurately distinguish the light change of the light receiver, but the principle of liquid blocking light is to change the propagation direction after reflecting the light, which is limited by the incident angle of the light beam There are limitations to changing the direction of propagation

Abstract

The present invention involves a signal controller used for temperature alarm, including: sealing temperature -sensitive body, relative settings on the light transmitter and signal control body on the inner wall of the temperature -sensitive body, as well as settings in the optical transmitter and signalControl the solid chemicals between the body; the signal control body includes: the alarm signal trigger connecting to the electrical connection with the optical receiver; the alarm signal trigger is also an external alarm;At the location, the alarm signal trigger is based on the intensity of the beam received by the optical receiver to send the alarm prompt information to the alarm; when the temperature in the body's body reaches the sublimation temperature of the solid chemical substance, the solid chemical substance is sublimated to a non -ferrous gas.The signal controller used for the temperature alarm in the present invention can make the light blocking effect more prominent and overcome the limitations of the light incident angle.

Description

technical field [0001] The invention relates to the technical field of temperature monitoring, in particular to a signal controller for temperature alarm. Background technique [0002] In the related art, based on the effect of thermal expansion and contraction of liquid to deal with light shading, a shading thermometer is designed, including a sequentially connected thermometer, light transmitter, light receiver and signal control body. The thermometer includes a scale plate and a glass tube containing liquid. On both sides of the glass tube, a light emitter and a light receiver are arranged perpendicular to the high temperature target scale position of the corresponding scale plate. When the liquid blocks the light beam emitted from the light emitter, the light receiver receives the light in the light beam from the light emitter after blocking The light intensity will decrease, and the signal control module outputs a conduction signal corresponding to the light change befo...
