Product Description

 

Car Battery Temperature Measuring Injection Silicone NTC Temperature Sensor 4.7k Ohm 3470

 

Description Of The NTC Temperature Sensor 4.7k Ohm 3470

 

With the widespread application of electric vehicles, people have higher and higher requirements for battery safety. As a parameter to measure battery status, temperature is an important monitoring object for battery safety. Traditional temperature sensors have problems such as large volume and complicated packaging. Due to this limitation, the prior art can only monitor the overall temperature of the battery box, and cannot perform differential temperature monitoring on a single battery.

 

 

Features Of The NTC Temperature Sensor 4.7k Ohm 3470

 

● Application description: Suitable for lithium battery temperature control module;
● Assembly method: Silicone card slot assembly.

● The assembly method is simple and firm.

● The resistance value and B value can be determined according to customer needs.

● The injection molding appearance and wire of the end can be customized.

● The wire nose series is specially designed for negative temperature coefficient thermistor temperature sensors.
● Long-term stability and anti-drift.
● High precision resistance and B value, good consistency and interchangeability. (The tolerance of resistance value and B value can be 1%)
● High sensitivity and fast response speed.
● Good insulation, mechanical shock resistance, bending resistance and high reliability.
● High temperature measurement accuracy.

 

 

Application Of The NTC Temperature Sensor 4.7k Ohm 3470

 

• New energy charging station NTC temperature sensor
• Smart Battery Management System (BMS) thermistor
• Lithium-ion electric vehicle battery energy storage battery PACK temperature sensor
• Temperature probe for temperature detection of electric car charging gun head
• Use NTC temperature sensor to monitor battery temperature during charging
