- Thermal wells: Using appropriate thermal wells to protect the sensor while maintaining good thermal contact
- Wiring: Proper wiring techniques to minimize electrical noise and interference
- Orientation: Correct orientation of the sensor to avoid measurement errors due to self-heating or fluid flow effects
Accuracy Specifications and Performance of the Rosemount 214C Temperature Sensor
Precision and Resolution
The Rosemount 214C Temperature Sensor is renowned for its high precision and resolution. Precision refers to the sensor's ability to consistently reproduce the same reading under identical conditions, while resolution indicates the smallest temperature change that the sensor can detect. Typically, the Rosemount 214C boasts a precision of ±0.1°C or better, depending on the specific model and configuration. This level of precision is crucial in applications where even small temperature variations can have significant impacts, such as in pharmaceutical manufacturing or food processing industries. The resolution of the Rosemount 214C is equally impressive, often capable of detecting temperature changes as small as 0.01°C. This high resolution allows for the detection of subtle temperature fluctuations, making it invaluable in processes that require extremely tight temperature control.
Accuracy Ranges
The accuracy of the Rosemount 214C Temperature Sensor varies depending on the temperature range being measured. Generally, the sensor maintains its highest accuracy within a specific optimal range, with slight variations at the extremes of its operational spectrum. For instance, in the most commonly used temperature range of -50°C to 250°C, the Rosemount 214C typically achieves an accuracy of ±0.15°C or better. At higher temperatures, up to 600°C, the accuracy might be in the range of ±0.25°C to ±0.5°C, which is still remarkably precise for such extreme conditions. It's important to note that these accuracy specifications can vary based on the specific model, calibration, and application. Rosemount provides detailed accuracy curves and specifications for each variant of the 214C sensor, allowing users to select the most appropriate model for their specific needs.
Long-term Stability
One of the most significant attributes of the Rosemount 214C Temperature Sensor is its exceptional long-term stability. This characteristic refers to the sensor's ability to maintain its accuracy over extended periods without significant drift.
The Rosemount 214C is engineered to minimize drift, often maintaining its accuracy within ±0.1% of its span per year. This remarkable stability is achieved through:
- High-quality materials that resist degradation over time
- Advanced manufacturing processes that ensure consistency in sensor production
- Sophisticated compensation algorithms that account for aging effects
Conclusion
The Rosemount 214C Temperature Sensor stands out for its exceptional accuracy, precision, and long-term stability.
