Resistance Temperature Detectors (RTDs) are temperature sensors that exhibit a change in resistance in response to variations in temperature. These devices utilize specific metals known for their predictable change in resistance as the temperature fluctuates.
RTDs are available in a wide range of resistance values, typically ranging from 10 to 1.85K ohms. The selection of a specific RTD depends on the desired temperature range and the accuracy required for the application. Additionally, each RTD has its own range of resistance tolerances that must be taken into consideration when selecting the appropriate sensor.
RTDs come in various forms, including free-hanging, panel mount, chassis mount, surface mount, or through-hole configurations. This allows for flexibility in mounting options, making them suitable for different installation requirements.
The accuracy and stability of RTD temperature sensors make them widely used in industries such as HVAC, industrial automation, and scientific research. Their predictable and consistent resistance-temperature relationship ensures reliable and precise temperature measurements.
In summary, RTDs are temperature sensors that change their resistance relative to temperature variations. With a range of resistance values and mounting options, they offer accurate and stable temperature measurement capabilities for a variety of applications.
