The temperature sensor (temperature detector) is the key fire detection component of the heptafluoropropane gas fire extinguishing system, which is used to monitor the temperature change in the protection area in real time, and trigger a fire when the temperature rises abnormally, and the linkage fire extinguishing system starts. This product strictly follows countries such as * * "Design Specifications for Automatic Fire Systems" (GB 50116-2013) and "Gas Fire Extinguishing Systems and Components" (GB 25972-2010) * *, and has the characteristics of high precision, fast response, and anti-interference. It is suitable for data centers, power facilities, cultural relics warehouses and other places that are sensitive to temperature.
Point type temperature detector: JTW-ZD-A20
1. High-precision detection
With NTC thermistor or thermocouple sensing technology, the temperature detection error is ≤ ± 1 °C (@ 25 °C benchmark).
Multi-level temperature rise rate judgment can distinguish between temperature rise (such as air conditioning failure) and fire rapid temperature rise and false alarm.
2. Quick response
≤ 10 s response time (when the temperature rise rate is ≥ 5 °C/min), much faster than ordinary civil temperature detectors (usually ≥ 30 s).
Support differential temperature and fixed temperature composite detection (in line with the requirements of GB 50116 for gas fire extinguishing systems).
3、Anti-jamming design
Electromagnetic shielding structure, passed GB/T 17626 electromagnetic compatibility test (electrostatic discharge, surge immunity, etc.).
Anti-corrosion coating, suitable for high humidity, salt spray and other harsh (such as coastal areas, chemical plants).
4. Easy to install and maintain
Universal adjustable bracket supports horizontal/vertical multi-angle installation (suitable for special positions such as air ducts and cabinets).
Modular design, the temperature sensor can be quickly replaced without recalibration.
