New product for detecting abnormal temperatures in electrical equipment / temperature detection line.

New product for detecting abnormal temperatures in electrical equipment / temperature detection line.

■Characteristics of Temperature Detection Lines 1. Abnormal temperatures of electrical wires can be monitored regularly and detected collectively. 2. Abnormal temperatures of power (control) equipment and electrical (load) equipment can be monitored regularly and detected collectively. 3. Wiring similar to that of electrical equipment can be achieved. 4. By utilizing shape memory alloy (restoration) and electrical wires (softening) to create a short circuit (contact) between the two wire cores, abnormal temperatures are detected and converted into signals. 5. It is a simple, easy, and accurate eco-technology product with zero standby power due to its switching function. 6. It can detect temperature and signals simultaneously, with a simple circuit configuration (switching function) at a low cost. 7. Shape memory alloy has permanent memory, is rust-free, and retains its shape indefinitely once activated. 8. The operation is a physical action that does not require power, ensuring no malfunction, and it can be used accurately and swiftly for many years. 9. Temperature detection can be performed directly without the need for measuring instruments. 10. It can be used for indoor and outdoor wiring. 11. It is a non-return type that allows for confirmation after activation. (Once sensing is activated / cannot be reactivated. The activated area can be deleted and reconnected.)

Detecting abnormal heat (abnormal temperature) of the storage battery with standby power at 0 / New product for temperature detection sensors for storage batteries.

■Features of Temperature Detection Sensors for Storage Batteries 1. It can monitor and detect abnormal heat generation (abnormal temperature) of storage batteries on a daily basis. 2. It can monitor and detect abnormal temperatures of the wiring and electrical equipment in the charging/discharging circuits of storage battery systems on a daily basis. 3. Inspection tasks for storage battery systems can be performed by anyone, ensuring reliable and safe maintenance management. 4. By utilizing shape memory alloys (restoration) and wires (softening) to create a short circuit (contact) between the two wires, it detects abnormal temperatures (maximum allowable temperature) and generates a signal. [Set temperature 70°C] 5. It is a simple, easy-to-use, and accurate eco-technology product with zero standby power due to its switching function. 6. It can simultaneously detect temperature and generate signals, with a simple circuit configuration (switching function) at a low cost. 7. Shape memory alloys have permanent memory, are rust-free, and maintain their state indefinitely once activated. 8. The operation is a physical action that does not require power, ensuring no malfunction and allowing for swift, accurate use over many years. 9. Direct temperature detection is possible without the need for measuring instruments. 10. It is a non-resettable type that allows for confirmation after activation. (Once sensing is activated, it cannot be reactivated. The activated location can be deleted and reconnected.)

Detect abnormal temperatures in distribution board equipment / Temperature detection sensor for distribution boards

■Features of Temperature Detection Sensors for Distribution Boards 1. Continuously monitors and detects abnormal temperatures of electrical wires in the distribution board. 2. Continuously monitors and detects abnormal temperatures of power (control) equipment and electrical (load) equipment in the distribution board. 3. Inspection tasks for distribution board equipment can be performed by anyone, ensuring reliable and safe maintenance management. 4. Utilizes shape memory alloy (restoration) and electrical wires (softening) to create a short circuit (contact) between the two wire cores, detecting abnormal temperatures (maximum allowable temperature) and generating a signal. [Set temperature: 80°C] 5. A simple, easy-to-use product with good accuracy, featuring eco-friendly technology with zero standby power due to its switching function. 6. Capable of simultaneous temperature detection and signaling, with a simple circuit configuration (switching function) at a low cost. 7. Shape memory alloy has permanent memory, is rust-free, and retains its function indefinitely once activated. 8. Operates through a physical action that requires no power, ensuring no malfunction and allowing for swift, accurate use over many years. 9. Enables direct temperature detection without the need for measuring instruments. 10. Non-resettable, allowing for confirmation after activation. (Once triggered, it cannot be reactivated. The activated location can be deleted and reconnected.)
