Linear sensor thermal wires are used for detecting the fire in the areas they are located in cases of fire. In this system, it is aimed to detect fire by fastening the thermal wire on surfaces in the area desired to be protected from fire. As for detection period, detection can be performed within 10 up to 40 seconds depending on magnitude, class of fire and the area it bursts out. When the ambient temperature reaches to 180 °C, the structure of the wire starts to get damaged and the outer layer melts and the wires inside touch each other and conduct fire alarm to control box.
Linear heat sensor wires (LHSW) are used to detect changes in temperature and are typically used in fire detection systems within a building or structure. LHSW’s rely on a change in resistance when the conductive wires attached to the cable approach their melting point, indicating an increase in temperature.
This allows for faster and safer detection of fires, particularly in high-risk areas such as large industrial facilities and businesses. LHSW’s have become a standard feature in many fire detection systems and are often used in conjunction with flame detectors or smoke detectors.
Linear heat sensor wire can be used in many different places, including:
Fire detection systems: Linear heat sensor wire is used to detect changes in temperature in fire detection systems within a building or structure.
Industrial applications: This cable can be used to monitor temperature changes in pipeline systems, electrical panels, and other industrial equipment.
Fire prevention systems: Linear heat sensor wire can be used in fire prevention systems to detect overheating and prevent it.
Cooling systems: This cable can be used to control the operation of coolers by monitoring temperature changes in cooling systems.
Security systems: LHSW can be used in security systems to detect temperature changes and sound an alarm in case of danger.
Linear heat sensor wire is typically used in high-risk areas and helps with early warning and intervention.
Linear heat sensors are typically used to detect temperature changes along a fixed line over long distances. These sensors can come in different types, but the most common ones are:
Thermistor Linear Sensors: These sensors are made of metal oxides and measure changes in resistance in response to temperature.
Platinum RTD Linear Sensors: These sensors are made of platinum wires, and the wire’s resistance changes with temperature.
Fiber Optic Linear Sensors: This is a new technology that uses optical fibers. Fiber optic sensors measure temperature changes using the interaction of light with temperature changes.
Bimetallic Linear Sensors: These sensors use a thermally sensitive element made of two different metals. Temperature changes cause the element to change shape, which is then converted into an electrical signal.
When choosing between these sensors, it is important to consider the conditions and requirements of the environment where the measurement will take place.
The characteristics of LINEAR HEAT SENSORS can vary depending on the sensor type. However, some common features of LINEAR HEAT SENSORS are:
These features make LINEAR HEAT SENSORS ideal for different applications. However, which features are important depends on the mechanical, electrical, and environmental factors in which the sensor will be used.
LINEAR HEAT SENSOR test standards can vary depending on the sensor type and its intended use. However, there are some general standards:
These standards indicate that LINEAR HEAT SENSORS need to undergo specific tests, and their compliance is evaluated based on the results of these tests. Tests may include measuring temperature sensitivity, response time, reliability, vibration resistance, and moisture resistance, among other features.
A LINEAR HEAT SENSOR is a sensor that detects temperature changes along a line. It is commonly used in fire alarm systems to provide early warning of a potential fire hazard before it becomes a serious threat. LINEAR HEAT SENSORS can be used as an alternative or in conjunction with traditional fire detection devices, and are also used in industrial settings, facilities, and other applications.
The working principle of LINEAR HEAT SENSORS is to activate the alarm system when the temperature rises above a certain level. They are typically mounted on a fixed line and detect temperature changes throughout the entire length of the line. This provides early warning to personnel at the scene, allowing them time to take action and control the fire before it becomes too severe.
