100K NTC Thermistor Temperature Sensor
A 100K NTC (Negative Temperature Coefficient) thermistor is a type
of temperature sensor whose resistance decreases as the temperature
increases. The "100K" designation refers to the nominal resistance
of the thermistor at a standard temperature, often 25 degrees
Celsius.
Nominal Resistance: The nominal resistance of the thermistor at a standard temperature
(usually 25°C) is 100,000 ohms or 100 kilohms (K).
Temperature Coefficient: NTC thermistors have a negative temperature coefficient, meaning
that their resistance decreases as the temperature rises. The rate
at which the resistance changes with temperature is specified by
the temperature coefficient (usually given in units of ohms per
degree Celsius, ohms/°C).
Application: NTC thermistors are commonly used in temperature-sensing
applications. They can be integrated into various devices and
systems to monitor and control temperature.
Circuit Connection: In a simple circuit, the NTC thermistor is often connected as one
leg of a voltage divider circuit along with a fixed resistor. The
voltage across the NTC thermistor changes with temperature, and
this change can be measured and converted to a temperature value
using appropriate circuitry.
Calibration: Calibration is necessary to correlate the resistance of the
thermistor with the actual temperature. This involves measuring the
resistance at known temperatures and creating a calibration curve.
Accuracy and Response Time: The accuracy and response time of the sensor depend on factors
such as the quality of the thermistor, the circuit design, and the
overall system integration.
Applications: NTC thermistor temperature sensors find applications in a wide
range of fields, including industrial automation, automotive
systems, HVAC (heating, ventilation, and air conditioning), and
medical devices.
Application:
Temperature measurement, temperature monitoring, etc.
