Unlike their NTC counterparts, PTC thermistors have a non-linear response to temperature, making them less suitable for precise temperature measurements. PTC thermistor sensors are primarily used in overcurrent protection and self-regulating heating applications due to their unique resistance behavior.
Resistance Temperature Detector (RTD) Sensor for Chery
Resistance temperature detector (RTD) sensors for Chery are not common in the automotive industry. They are preferred in industrial applications where precise temperature measurement is paramount. These sensors are highly accurate, stable, and reliable, making them suitable for critical temperature control in industrial processes. RTD sensors use pure metals, such as platinum, copper, and nickel, as sensing elements. They offer excellent linearity and a wide temperature range, making them ideal for applications where temperature fluctuations can significantly impact performance and safety.
Temperature Sensor for Chery QQ
The Chery QQ uses the NTC type temperature sensor. The sensor's resistance at 25 degrees Celsius is 10,000 ohms ± 1%. The sensor's beta value, which is a measure of its sensitivity to temperature changes, is 3950K ± 1%. The Chery QQ's Engine Control Unit (ECU) expects the sensor to provide a resistance range of 2000 to 20,000 ohms to indicate temperatures between -40 and 120 degrees Celsius.
Temperature Sensor for Chery Tiggo
The Chery Tiggo also utilizes NTC sensors. However, the resistance and beta value specifications may differ slightly to accommodate the vehicle's engine characteristics. For the Chery Tiggo, the NTC temperature sensor's resistance at 25 degrees Celsius is 12,000 ohms ± 2%, with a beta value of 4000K ± 2%. The ECU's resistance range and temperature equivalents are the same as those for the Chery QQ.
Temperature Sensor for Chery Fulwin
The Chery Fulwin uses a PTC temperature sensor. This type of sensor has a positive temperature coefficient, meaning its resistance increases with temperature. The PTC sensor's resistance at 25 degrees Celsius is 5 ohms ± 5%. Its alpha value, which indicates the rate of resistance change with temperature, is 0.5 ± 10%. The Chery Fulwin's ECU is designed to work with the PTC sensor's unique characteristics to ensure optimal engine performance.
