Temperature detection sensor for storage batteries

1. This is a product that connects a temperature detection sensor with a code. It is connected using crimp sleeves or connectors. 2. The temperature detection sensor is equipped with a shape memory alloy coiled around a soluble insulated wire. When the surrounding temperature reaches the set temperature (80°C), the wire softens, and the shape memory alloy constricts the wire (restores), short-circuiting the two wires to detect temperature and sending a signal (no voltage/a contact) for temperature detection. 3. By setting the temperature detection sensor to the abnormal temperature of the equipment, it can detect abnormal temperatures. In other words, by installing temperature detection sensors on various industrial and equipment devices, it can detect abnormal temperatures that may lead to equipment damage or fire. The abnormal temperature is set to the set temperature (80°C). 5. For example, when installed on various industrial and electrical equipment, if abnormal heat (abnormal temperature) occurs, the temperature detection sensor with a code detects the abnormal temperature and alerts through an alarm or similar device. 6. In this way, abnormal temperatures of various industrial and electrical equipment can be monitored continuously on a daily basis, allowing for early detection and initial response to prevent equipment damage or fire. Maintenance management is reliable and safe.

This device is a "battery alarm device" that allows for easy monitoring and alarming of abnormal temperatures in batteries by attaching a temperature sensing wire to the battery and connecting it to a small alarm panel. The temperature sensing wire is structured by combining numerous shape memory alloys at equal intervals on an extended electric wire, and when the surrounding temperature reaches the set temperature (70°C), the two wires short-circuit to generate a temperature sensing signal. It is a temperature sensor-equipped wire that can be easily installed by extending it, employing eco-technology with zero standby power for the switching function that anyone can easily operate. This product meets the performance standards of type 1 fixed temperature detectors (120 seconds) as specified by fire safety regulations, making it ideal for the regular monitoring of abnormal temperatures in batteries and battery equipment. ■ Contact information for this matter 2-2-8 Minami Tsutsujigaoka, Kameoka City, Kyoto Prefecture, 621-0847 Space Works Contact: Wada wadakame@siren.ocn.ne.jp TEL: 0771-25-3430 / FAX: 0771-25-4932

■Overview of Temperature Detection Wire 1. This product integrates a large number of shape memory alloys (temperature detection sensors) at equal intervals along an extended wire. However, it is designed to correspond to the maximum allowable temperature of the wire. 2. This maximum allowable temperature is the temperature at which the insulation of the wire rapidly deteriorates. The set temperature corresponds to the maximum allowable temperature (70°C). 3. By detecting the maximum allowable temperature of the wire, it is possible to detect abnormal temperatures associated with electrical equipment fires. 4. The temperature detection wire is attached to the wire, allowing for the collective detection of abnormal temperatures due to overload current or poor connections in the wire, for each temperature detection wire. (Abnormal temperature detection of the wire) 5. Temperature detection wires are installed inside and outside power (control) devices and electrical (load) devices, enabling the collective detection of abnormal temperatures due to overload or device failures for each temperature detection wire. (Abnormal temperature detection of devices) 6. For example, when an abnormal temperature associated with a fire occurs in wires, power (control) devices, or electrical (load) devices, the temperature detection sensors attached to each temperature detection wire continuously monitor and collectively detect abnormal temperatures. Alarms or other devices notify of abnormal temperatures associated with fires.

■Overview of Temperature Detection Sensor for Storage Batteries 1. This is a product with a temperature detection sensor connected by a wire. It is connected using crimp sleeves or connectors. 2. The temperature detection sensor integrates a shape memory alloy with the wire, utilizing the softening of the wire and the restoration of the shape memory alloy to create a short circuit (contact) between the two wire cores, thereby detecting the maximum allowable temperature and generating a signal. The set temperature corresponds to the maximum allowable temperature of the wire (70°C). 3. The maximum allowable temperature is the temperature at which the insulation of the wire rapidly deteriorates. Therefore, detecting the maximum allowable temperature indicates the detection of abnormal temperatures in the wire. 4. Mounted on the outer wall of the storage battery, it detects abnormal heat (abnormal temperatures) due to internal short circuits, external short circuits, or external overheating, and alerts through alarms to prevent fires caused by ignition or explosion. 5. For example, when abnormal heat (abnormal temperature) occurs in a storage battery, the temperature detection sensor mounted on the outer wall of the storage battery detects the abnormal temperature and alerts through alarms. 6. In this way, it is possible to continuously monitor the abnormal heat (abnormal temperature) of the storage battery and the abnormal temperatures of the wires and electrical equipment in the charging/discharging circuit of the storage battery system, thereby preventing equipment damage and fires. Maintenance management can be conducted reliably and safely.
