NTC thermistors for temperature detection

Thermistor – Temperature Detection Fire Alarm Example

Thermistors serve a crucial role in temperature detection. For example, thermistor temperature detection can be used in fire alarms to detect fires based on a sudden change in temperature. Unlike photoelectric detectors or ionization alarms, thermistors only require heat to activate. Thermistors are temperature-sensing elements made of semiconductor material that displays large changes in resistance in proportion to small changes in temperature. Photoelectric and Ionization Fire Alarms The photoelectric detector requires heavy smoke … Continue Reading

Thermistors used to Measure Temperature in Lake Tahoe

Recently, the SFGate released an article about how thermistors are used to measure temperature change in Lake Tahoe. The article states that over the past 40 years, global warming has caused the temperature of lakes to rise, affecting the natural habitat for fish species and algae blooms. Scientists at the Tahoe Environmental Research Center carefully monitor the lake’s temperature using thermistors carried by large ocean buoys. Signals from the buoys transmit data via satellite to scientists at NASA’s Jet Propulsion Laboratory in … Continue Reading

ACCU-CURVE™ Thermistors for High Accuracy Temperature Sensing

What’s an ACCU-CURVE™ Thermistor? ACCU-CURVE™ thermistors are used for high-accuracy temperature sensing, control, and compensation in medical, industrial, and automotive applications. They also deliver long-term stability and reliability, while offering interchangeability over a broad temperature range. This eliminates the need to individually calibrate or provide circuit compensation for part variability. Accurate temperature measurement to ±0.2°C is available over the 0°C to 70°C temperature range. Standard ohmic values at 25°C range from 2,252 to 100,000 ohms. ACCU-CURVE™ Thermistor vs. … Continue Reading

Temperature Sensor for Control and Compensation Circuits

To use a temperature sensor in a control or compensation circuit, the detection circuit must provide an output in a usable format.  For analog circuits, the output is usually a resistance.  For digital control and compensation, the measurement needs to be converted to a digital format for processing by an MCU.  This is commonly achieved by reading the measurement as a voltage using an analog to digital converter (ADC). Semiconductor-based sensors … Continue Reading
