Structure and application
KI-31 serial products are the temperature controllers taking bimetallic strip as the temperature-sensing unit. In case of normal operation the electrical appliance, the bimetallic strip is in a free state; the contact point is in a state of close/open. When the temperature reaches the action temperature, the bimetallic strip performs quick action generates caused by internal stress due to heating; open/close the contact point; disconnect/connect the circuit; thus, the temperature is in control. When the electrical appliance is cooled to the recovery temperature, the contact point automatically opens/closes to recover normal operation state.
Widely used in electrical heating appliances like water dispenser, water heater, sandwich bread baker, dishwasher, dryer, sterilizing cupboard, micro-wave oven, electric heating coffee pot, electric cooker, refrigeratory, air-conditioner, laminator, heater of auto seat. Characteristics of Industrial Programmable Bimetal Thermostat
Stable performance, high accuracy, small size, lightweight, high reliability, long lifespan, less interference to radio
Precautions
1.When adopting contact temperature sensing installation, the surface of the metal cover is required to be securely contacted with the installing surface of the controlled device. For ensuring the temperature sensing effect, it is required to coat thermal conductive grease or other similar thermal conductive medium on the surface of temperature sensor.2.For reliable performance, collapse, loose or distorted top part of the cover is prohibited during installation.3.Liquid inleakage into the controller, crackle in the casing and unauthorized change of external terminal position are prohibited. 4.When the product is used in the circuit with maximum current of 5A, the cable with copper core at section 0. 5-1mm2 is required for connection; When the product is used in the circuit with maximum current of 10A, the cable with copper core at section 0.75-1.5 mm2 is required for connection; 5.The product should be kept in a clean, dry and corrosive gas-free warehouse with good ventilation and at relative humidity below 90%, environment temperature below 40°C.
