Types of Sensors Quiz

Devices and Measurement Conversion

• A transducer converts a physical variable (such as temperature, pressure, or light) into an analog electrical quantity, facilitating the measurement of these variables.

Platinum Resistance-Temperature Detector (RTD)

• Main characteristic: Operates on the principle that a material's resistance changes predictably with temperature, providing accurate and stable temperature measurements.
• Known for high accuracy and repeatability over a wide range of temperatures.

Nickel Resistance-Temperature Detector (RTD)

• Typical measurement range: Generally around -60°C to 200°C, although specific models may extend this range.

Construction of Resistance-Temperature Detector (RTD)

• Typically constructed from a thin wire of pure metal (such as platinum or nickel) wound around a ceramic or glass core, ensuring a stable and accurate temperature response.
• May be encapsulated in protective materials to enhance durability and minimize environmental impact on the readings.
