A temperature sensor is a device designed to measure and report the temperature of a specific environment, substance, or material. It converts temperature data into a readable format for monitoring and analysis.

Temperature sensors work by detecting changes in physical properties or electronic signals that correspond to temperature variations. Common types, such as thermocouples and thermistors, measure electrical changes, while infrared sensors detect thermal radiation.

The main types include thermocouples, which measure temperature differences; thermistors, known for their precision in a limited range; RTDs (Resistance Temperature Detectors), which offer accuracy over a wide range; and infrared sensors, which measure surface temperature without contact.

They are widely used in industries like manufacturing, automotive, healthcare, food processing, and HVAC (Heating, Ventilation, and Air Conditioning), as well as in consumer electronics and environmental monitoring.

Consider factors like temperature range, accuracy requirements, environmental conditions (e.g., humidity, presence of chemicals), response time, and the need for contact or non-contact measurement.

Accuracy varies by type and model. RTDs are known for high accuracy, while thermistors are precise in limited ranges. Manufacturers typically specify the accuracy level in the product documentation.

Yes, certain types are designed for extreme conditions. Thermocouples can measure very high temperatures, making them suitable for industrial furnaces, while cryogenic temperature sensors are used for very low temperatures in scientific research.

Installation depends on the sensor type and application. Generally, ensure it's placed in a representative location, away from direct sunlight or heat sources for accurate readings. Follow manufacturer guidelines for specific installation instructions.
Maintenance includes regular calibration to ensure accuracy, cleaning to remove any buildup that could affect readings, and checking wiring and connections for wear or damage.
