Temperature detection sensor for distribution boards

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 product is a "danger temperature alarm" that connects a temperature sensing wire to a small alarm panel to monitor and alert for dangerous temperatures (80°C). It features a structure where a shape memory alloy is combined at equal intervals along an extended wire; when the surrounding temperature reaches the set temperature (80°C), the two wires short-circuit to sense the temperature and send a signal. It adopts eco-friendly technology with zero standby power, making it easy for anyone to install. Despite its simplicity, it offers good accuracy and can be used for both indoor and outdoor wiring, allowing for wiring similar to that of electrical equipment. This product meets the performance standards of type 1 fixed temperature detectors (120 seconds) as specified by fire safety regulations, making it ideal for use in places at risk of dangerous (abnormal) temperatures, such as buildings under construction, plant factories, thermal power generation, various conveyors, and chemical industry piping. ■ Contact information regarding 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 Sensor for Distribution Boards 1. This is a product with a temperature detection sensor (80℃) connected by a cable. It is connected using crimp sleeves or connectors. 2. The temperature detection sensor for the distribution board is installed in close contact (touch) parallel to the wires of each circuit in the distribution board. 3. The temperature detection sensor for the distribution board is installed in close contact (touch) with the control devices (such as Mg, S/inverters) and load devices of each circuit in the distribution board. 4. For example, in the case of wires, when abnormal temperatures occur due to overload current, faulty electrical equipment, or poor wire connections, the temperature detection sensor attached to the wire detects the abnormal temperature and alerts through an alarm or similar device. 6. In this way, abnormal temperatures of the wires and control devices or load devices in each circuit of the distribution board can be continuously monitored, allowing for early detection and initial response to prevent equipment damage or fire. Maintenance management can be performed reliably and safely. [Note 1]: The temperature detection sensor is integrated with a shape memory alloy combined with the wire, utilizing the softening of the wire and the recovery 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 (80℃).

■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.
