Temperature Sensor Types 1. Negative Temperature Coefficient (NTC) thermistor A thermistor is a thermally sensitive resistor that exhibits a continuous, small, incremental change in resistance correlated to variations in temperature. An NTC thermistor provides higher resistance at low temperatures. As temperature increases, the resistance drops incrementally, according to its R-T table.

A thermistor is a type of resistor whose resistance is strongly dependent on temperature, more so than in standard word is a combination of thermal and are widely used as inrush current limiters, temperature sensors (negative temperature coefficient or NTC type typically), self-resetting overcurrent protectors, and self-regulating heating elements (positive ...
· Your vehicle is equipped with a number of sensors that are used for monitoring all kinds of information. Among them is the knock sensor, which is a listening device located near the engine that detects vibrations caused by engine detonation or “knock.” P0327 is one of several trouble codes related to a faulty knock sensor. If your scan tool is showing this code, read on to learn more about the …
•1) Deflection: The signal produces some physical (deflection) effect closely related to the measured quantity and transduced to be observable. •2) Null: The signal produced by the sensor is counteracted to minimize the deflection. That opposing effect necessary to maintain a zero deflection should be proportional to the signal of the measurand

NTC Thermistors are non-linear resistors, which alter their resistance characteristics with temperature. The resistance of NTC will decrease as the temperature increases. The manner in which the resistance decreases is related to a constant known in the electronics industry as beta, or ß. Beta is measured in °K. NTC Thermistor Probes.

Another type of sensor, that is made using the PTC Thermistor, is ofcourse the temperature sensor. Here when these PTC are used, only their steep region of R/T characteristic is considered. Also, the resistance is regarded as a function of ambient temperature given that varistor effect is excluded. These sensors come in handy at places where temperature limit is needed for protection purposes.
The temperature sensitivity of an NTC sensor is expressed as “percentage change per degree C" or "percentage change per degree K". Depending on the materials used and the specifics of the production process, the typical values of temperature sensitivities range from -3% to -6% / °C. Characteristic NTC curve. As can be seen from the figure, the NTC thermistors have a much steeper resistance ...
· A Knock Sensor or a Vibration Sensor is a simple device that detects vibrations or shocks from knocking or tapping it. It is basically an electronic switch which normally open. When it detects any shock or vibrations, it closes (for that moment and returns back to its default open position).
· Diagnostic trouble code (DTC) P0325 stands for Knock Sensor Malfunction (Sensor 1, Bank 1). The code indicates your car’s primary computer, which is often referred to as the powertrain control module (PCM), perceives a problem with the knock sensor or its circuit. Code P0325 means that your car computer detects a problem with the knock sensor unit ...
