Temperature-sensing cables for cable trays
2025-09-28 09:40:37
1) The temperature-sensing cable has a stable structure, strong anti-interference and tensile performance.
2) The detector has differential fixed-temperature detection performance. Compared with traditional fixed-temperature detectors, its fire detection effect is more sensitive.
3) After the detector alarms within the safe temperature range, the temperature-sensing cable will not be damaged, and the temperature-sensing cable can be reused.
4) The microcomputer modulator and terminal processor adopt metal casings, which are corrosion-resistant and anti-aging.
5) The microcomputer modulator is equipped with a Chinese character LCD screen, and all kinds of alarm information can be presented in Chinese characters
It is displayed on the LCD screen for the convenience of user operation.
6) The detector has strong anti-interference ability and adopts good grounding measures, isolation detection and software anti-interference
Interference technology can be applied in places with strong electromagnetic field interference.
