Dedicated Linear Temperature Sensor for Electrical Fire Monitoring
This series of temperature sensors serves as a high-precision, front-end temperature acquisition component specifically designed to interface with electrical fire monitoring detectors (signal processing units). Featuring a compact and exquisite design (with dimensions of merely φ4 mm) and utilizing high-performance lead materials, these sensors are engineered to be mounted in close contact with critical, heat-prone points within power distribution networks. They rapidly convert abnormal temperature fluctuations—caused by factors such as poor contact or electrical overload—into electrical signals for transmission, thereby fundamentally eliminating fire hazards stemming from overheating electrical connections.
Description
Product Advantages
1. Aviation-Grade High-Quality Cabling: The cable material is meticulously selected polytetrafluoroethylene (PTFE/Teflon). This material boasts exceptional resistance to high temperatures, superior insulation properties, and excellent resistance to corrosion and aging, ensuring the sensor operates with long-term stability within the complex and harsh environments of power distribution cabinets.
2. High Sensitivity and Rapid Response: Featuring outstanding thermal characteristics, the sensor offers extremely fast response times and exceptionally high sensitivity, enabling it to acutely detect even the slightest anomalies in temperature.
3. Ultra-Wide Temperature Measurement Range: The measurement range spans from 55°C to 140°C. It is specifically optimized to target the critical threshold between the normal operating temperatures of electrical equipment and the temperatures indicative of early-stage fire hazards, ensuring precise detection without false alarms.
4. Compact, Exquisite Design and Easy Installation: With an external diameter of just 4mm, the sensor can be effortlessly inserted into narrow crevices within distribution cabinets or affixed to concealed busbar joints without disrupting the cabinet’s original structural layout.
5. Flexible Wiring: Supplied with a standard cable length of 2 meters—an optimal length that easily accommodates the wiring distances required for the vast majority of standard power distribution boxes and cabinets.
Scope of Application Scenarios
As the primary sensing interface of the Electrical Fire Monitoring System (Temperature-Sensing Type), it is primarily affixed to the following critical nodes—locations highly susceptible to overheating caused by excessive contact resistance:
1. Cable Joints and Terminations: At the incoming and outgoing cable connections within power and lighting distribution boxes.
2. Interiors of Distribution Boxes/Cabinets: At the upper and lower connection terminals of circuit breakers, and at the wiring terminals of contactors.
3. Switchgear Copper Busbars: At the copper busbar connections and branching points located within the main switchgear of low-voltage distribution rooms.
4. Terminals of Critical Electrical Equipment: At transformer wiring terminals and the power connection boxes of large-scale electric motors.
