Understanding the Rosemount 214C RTD Temperature Range
Temperature Range Specifications
The product boasts an impressive temperature range, making it suitable for a wide array of industrial applications. This sensor can accurately measure temperatures from -200°C to 850°C (-328°F to 1562°F). Such a broad range allows it to be utilized in diverse environments, from extremely cold cryogenic processes to high-temperature industrial operations. It's important to note that while it can operate within this extensive range, its performance characteristics may vary depending on the specific temperature being measured. The sensor's accuracy and stability are typically optimized for certain sub-ranges within its overall capability.
Accuracy Across Different Temperature Ranges
The accuracy of the Rosemount 214C RTD is not uniform across its entire temperature range. Generally, RTDs exhibit their highest accuracy in the mid-range temperatures, with slight deviations at extreme ends of their capability. For the Rosemount 214C RTD, the accuracy is often specified as a percentage of the reading or as a fixed value, whichever is greater. For instance, in the range of -50°C to 250°C, the accuracy might be ±0.1°C or 0.04% of the reading. As temperatures approach the extremes of the sensor's range, the accuracy may decrease slightly. However, the Rosemount 214C RTD maintains exceptional precision even at these limits, which is why it's favored in applications requiring high accuracy across a broad temperature spectrum.
Factors Influencing Temperature Range Performance
Several factors can influence the performance of the product within its temperature range. These include:
- Sensor construction: The materials used in the RTD element and its protective sheath can affect its stability and response time across different temperatures.
- Environmental conditions: Factors such as humidity, vibration, and electromagnetic interference can impact the sensor's accuracy, especially at temperature extremes.
- Calibration frequency: Regular calibration ensures the Rosemount 214C RTD maintains its accuracy across its entire temperature range.
- Thermal cycling: Repeated exposure to temperature fluctuations can affect the sensor's long-term stability and accuracy.
Understanding these factors is crucial for maintaining the product's performance throughout its specified temperature range.

Correct installation not only protects the sensor but also ensures it can accurately measure temperatures across its entire range without introducing errors due to environmental factors or improper placement.
Calibration and Maintenance
Regular calibration is essential to maintain the Rosemount 214C RTD's accuracy across its temperature range. This process typically involves:
- Comparing the RTD's readings to a known temperature standard at multiple points within its range
- Adjusting the sensor or its associated transmitter to correct any deviations
- Documenting the calibration process for traceability and compliance purposes
The frequency of calibration depends on the application's criticality, the sensor's usage conditions, and regulatory requirements. In addition to calibration, regular maintenance checks can help identify potential issues before they affect measurement accuracy.
Environmental Considerations
While the Rosemount 214C RTD is designed to operate across a wide temperature range, environmental factors can impact its performance. Considerations include:
- Vibration: In high-vibration environments, special mounting techniques or vibration-resistant models may be necessary to maintain accuracy.
- Thermal cycling: For applications with frequent temperature changes, selecting a sensor with appropriate thermal shock resistance is crucial.
- Corrosive environments: In chemically aggressive processes, proper material selection for the sensor sheath and thermowell is essential to prevent degradation and maintain accuracy.
