Sudden jump thermostat Characteristics :
Stable performance , high accuracy , small size , lightweight , high reliability , long lifespan , less interference to radio
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 .
Product Structure:
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 .
