Temperature Sensors
A temperature sensor is a device, typically, a thermocouple or RTD, that provides for temperature measurement through an electrical signal. A thermocouple (T/C) is made from two dissimilar metals that generate electrical voltage in direct proportion to changes in temperature. An RTD (Resistance Temperature Detector) is a variable resistor that will change its electrical resistance in direct proportion to changes in temperature in a precise, repeatable and nearly linear manner.

FAQ
- What are Temperature Sensors?
- Temperature sensors are electronic devices that measure and monitor the temperature of their surroundings, converting temperature changes into electrical signals for analysis and control.
- How do Temperature Sensors work?
- Temperature sensors use various principles, such as resistance, voltage, or current changes in response to temperature variations. These changes are then converted into temperature readings.
- What are the main types of Temperature Sensors?
- Thermocouples: Measure temperature using the voltage difference between two dissimilar metals. Resistance Temperature Detectors (RTDs): Measure temperature based on the change in electrical resistance of a metal. Thermistors: Change resistance with temperature and are often used for temperature compensation. Infrared (IR) Sensors: Detect temperature by measuring the infrared radiation emitted by an object. Semiconductor Temperature Sensors: Utilize the temperature-dependent properties of semiconductors.
- How do I choose the right Temperature Sensor for my application?
- Consider factors like temperature range, accuracy requirements, response time, physical size, environmental conditions, and compatibility with the measurement system. Consult datasheets and manufacturer resources for guidance.
