Термичка заштита мотора ПТЦ термистор

Polymer PTC Motor thermal protection. Полимерни ПТЦ за површинску монтажу (позитивни температурни коефицијент) Motor thermal protection using a conductive polymer polymer composite material as a main material. Different from the traditional ceramic PTC Motor thermal protection, усваја облик који се лако инсталира на површину за једноставну инсталацију; A polymer conductive composite material layer with a positive temperature coefficient of resistance effect is used as the core material of the polymer PTC Motor thermal protection. The cost of the product is lower than the ceramic PTC Motor thermal protection, which is more convenient to process and more suitable for the requirements of miniaturized devices.

Карактеристике
PTC linear positive temperature coefficient thermistor is made of PTC material and physical process. It has excellent stability, complex linearity, repeated millions of times, the characteristic curve is unchanged. The resistance value increases with the temperature, and changes linearly with good linearity. Compared with PTC polymer ceramic thermistors, the linearity is better, and no linear compensation measures are needed to simplify the circuit design. And the resistance value is consistent, the interchangeability is strong, the shape and specifications are guaranteed. High temperature sensing speed, 1-2 seconds in air medium, high sensitivity. Мала величина, sturdy structure, standardized appearance, suitable for automatic installation of printed circuit boards.

■ Application
It is widely used in temperature control, temperature measurement, and temperature compensation in industries such as communications, аутомобили, meters, computers, и кућних апарата. The universal PTC positive temperature thermistor's resistance temperature characteristic is abrupt, and the linear region is very narrow. Usually used for circuit overcurrent protection, not for temperature detection, temperature compensation circuit. This product complements this area of application.

The linear thermistors produced by our company are divided into two series. One is the monocrystalline silicon linear PTC thermistor SCKTY series, which is characterized by a large temperature coefficient of 7000PPM per degree, which can replace the KTY series thermistors of NXP and the DS series of RTI.

The other is a linear ceramic thermistor. Alternatively KOA company LT1 / 4Ц, LT1 / 6Ц, LP1 / 8Ц, characterized by small size adjustable temperature coefficient. It has a wide temperature coefficient (1000PPM-5000PPM) with a resistance range of (1Ω-50KΩ) and low price.

Let's introduce the SCKTY series first

Specifications of commonly used glass-sealed linear thermistors SCKTY: Can replace NXP (PHILIPS) KTY81, КТИ82, КТИ83, KTY84, KTY85, and DS series of RTI company.

The company is specialized in producing PTC temperature sensor of high-tech enterprises.PTC temperature sensor produced by the import of Philips silicon resistor components made of carefully,With high precision,Стабилност,Reliability, Product life long advantages,The temperature sensor has been widely used in the field of temperature measurement of solar water heaters color temperature control equipment,Automotive oil temperature measurement,Engine cooling system, Industrial control systems in the thermal protection,Heating control system,Power supply protection.
