Types of Evaporator Temperature Sensors
Did you know there are several types of evaporator temperature sensors? Each comes with its own set of pros and cons. Let’s dive in and explore the fascinating world of thermistor-based sensors, resistance temperature detectors (RTDs), and thermocouples.
Thermistor-based Sensors
Thermistors are a popular choice for evaporator temperature sensors. How do they work, you ask? Well, their resistance changes as the temperature fluctuates. But, as with everything in life, there are upsides and downsides to using thermistor-based sensors.
NTC Thermistors
NTC (Negative Temperature Coefficient) thermistors are the cool kids on the block. Their resistance decreases as the temperature rises, making them perfect for evaporator temperature sensing applications. Who wouldn’t want that kind of accuracy?
PTC Thermistors
On the other hand, PTC (Positive Temperature Coefficient) thermistors have a different story to tell. Their resistance increases with rising temperatures. Though they might not be the go-to choice for evaporator temperature sensing, they still have their place in the sensor world.
Resistance Temperature Detectors (RTDs)
Resistance temperature detectors, or RTDs, are another contender in the temperature sensor arena. They work by measuring the resistance change in a metal element as the temperature varies. But are they the best choice for your evaporator temperature sensor needs? Let’s weigh the pros and cons.
Thermocouples
Last but not least, we have thermocouples. These handy little devices generate a voltage based on the temperature difference between two metal junctions. But is this clever trick enough to make them the top choice for evaporator temperature sensing? Only time will tell.
Evaporator Sensor in Cars
