The working principle of the KSD9700 Thermal Sensor Protector is based on a bimetallic strip mechanism that automatically detects temperature changes and disconnects the power when necessary. Here's how it works:
Bimetallic Strip Mechanism: The KSD9700 contains a bimetallic strip made of two metals with different coefficients of expansion. When the temperature rises, the metals expand at different rates, causing the strip to bend.
Temperature Threshold Activation: The bending of the bimetallic strip triggers a switch that either opens or closes the circuit. When the temperature reaches a preset level (e.g., when it gets too hot), the strip bends enough to open the circuit and interrupt the power supply.
Power Cutoff: Once the circuit is opened, the KSD9700 disconnects the electrical current to prevent the appliance from overheating. This prevents damage to internal components, reduces the risk of fire, and ensures the appliance operates safely.
Reset Mechanism: Depending on the design, the KSD9700 may have an automatic reset function, where it restores the power supply once the temperature cools down to a safe level. Some models also feature a manual reset option.
In summary, the KSD9700 uses the expansion properties of two metals in a bimetallic strip to monitor temperature and automatically disconnect the power when temperatures exceed the safe limit, ensuring protection from overheating.
