PTC is the abbrevjazzjoni for Positive Temperature Coefficient, meaning a semiconductor material or component with a very high temperature coefficient. Normalment, we refer to PTC as a positive temperature coefficient thermistor, abbreved as PTC thermistor.
PTC termmistor is a tipiku semikonduttur resistor with temperatura sensittività. Meta it jaqbeż a ċert temperatura (Curie temperatura), its reżistenza valur żidiet pass pass b' iż-żieda tat temperatura.
PTC thermistors huma divided fi ċeramika PTC termistors u organiku polimeru PTC thermistors based on their material differences.
PTC thermistors are divided in automatic demagnetization PTC thermistors, delayed start PTC thermistors, constant temperature heating PTC thermistors, overcurrent protection PTC thermistors, overheating protection PTC thermistors, and sensors PTC thermistors based on their different uses.
When l-għażla PTC heaters, special attention should be paid to the heating medium. The material of the electric heating tube shell should have no corrosion benefits. PTC heaters been in use for a long time, and if hemm are thick pipe and oil stains clustered on the surface, they should be system on the surface, they should be removed on schedule. Otherwise, it will cause the electric heat transfer machine to lower and cause damage to the wiċċ sħana tagħbija ta ' il- pajp li jaqbeż il - rata tolleranza. PTC heaters għandu ikun maħżun fi a niexef stack. If il wiċċ is niedja due to permanent placement, a megohmmeter should be used to measure the insulation resistance. If it is less than 1 megohm/500 volts, the electric heating tube should be placed in a 200 degree drying oven for drying.
PTC heater, as a new type of thermistor material, can be classified into two main types of important applications: switch and fever. PTC materials have switch characteristics such as thermal sensitivity, current limiting, and delay, as well as contactless and noise free features with a long service life. Huma jistgħu be użati for friġġ starting, motor transformer protection, program controlled interchanger protection and mosquito repellent, curly hair perm, electric irons, and other small household appliances. The various heater products made from PTC with the characteristics of consolidating its function, rapidly heating up, and less less affected by power voltage fluttwazzjonijiet have become very ambitious replacement products for metall reżistenza wajer tip deni materjali. Bħalissa, IT been widely used in heaters, clothes dryers, air curtains, air conditioners, air conditioners, etc.
