What is the temperature sensing alarm will automatically alarm?

To answer this question, we must first understand the common temperature sensing alarm types.

Temperature sensing alarm temperature in the range from 20 kinds of classification, classification marks the most common are A1 and A1R, A2 and A2R. The A1 action temperature lower limit upper limit is 54 ℃, the operating temperature is 65 ℃; A2 operating temperature limit is 54 ℃, the upper limit temperature is 70 ℃ action. A1R and A2R with the "R" logo temperature alarm, more of a differential temperature alarm function. Differential temperature alarm is within a certain period of time, the numerical environment temperature exceeds the alarm value will alarm. Differential temperature detector is 54 ℃ -70 ℃, according to the national standard, detect the temperature up to a maximum of 160 ℃.

So, to answer this question is to look at specific temperature sensing alarm types and models. In order to Kai Wei letter Shenzhen city Safe Technology Ltd production of JTW-ZCD-805C network type temperature detector as an example, when the temperature exceeds the set value (57 ℃ -62 ℃) or environmental temperature 1 minutes on appreciation of more than 8.3 ℃, the alarm will automatically alarm.
