What are Fluke Calibration Liquid/Micro Bath Calibrators?
Fluke Calibration's Liquid and Micro Bath Calibrators are portable devices designed to provide stable temperature environments for calibrating temperature sensors. Unlike dry-block calibrators, these baths use a fluid medium, allowing for uniform heat distribution and accommodating various sensor shapes and sizes.
What Do Fluke Calibration Liquid/Micro Bath Calibrators Measure?
These precision calibration baths are designed to establish a highly stable and uniform thermal environment for the calibration and verification of temperature sensors. While the baths themselves do not perform temperature measurements, they enable accurate comparison by immersing probes into a liquid medium maintained at a controlled setpoint. Key specifications across the range include:
- Temperature Range: Model-dependent, covering ranges from –30?°C to +300?°C, suitable for a wide variety of industrial and laboratory applications.
- Stability: Thermal stability as high as ±0.02?°C enables repeatable calibration conditions across extended durations.
- Uniformity: Typical bath uniformity of ±0.02?°C minimizes spatial temperature gradients, ensuring consistent conditions throughout the immersion area.
- Accuracy: System accuracy up to ±0.25?°C supports precise sensor calibration; some models may allow for reference-free operation within specified tolerances.
- Immersion Tank Dimensions: Vary by model; typical configurations accommodate sensors with lengths up to 140?mm and diameters up to approximately 48?mm.
These baths are compatible with various temperature sensor types, including thermocouples, RTDs, and thermistors, and are suitable for both on-site and laboratory use depending on the model.
How Do Fluke Calibration Liquid/Micro Bath Calibrators Work?
The calibrators utilise a fluid medium, such as silicone oil, to create a uniform temperature environment. Sensors are immersed in the bath, and the calibrator maintains the set temperature with high stability. Features like RS-232 ports and compatibility with software such as MET/TEMP II facilitate automated calibration processes and data logging.
Applications of Fluke Calibration Liquid/Micro Bath Calibrators
These calibrators are widely used in various settings, including:
- Calibration Laboratories: Ensuring the accuracy of temperature measurement devices.
- Research and Development: Testing new temperature sensors and systems.
- Industrial Maintenance: Regular calibration of sensors in manufacturing processes.
- Field Calibration: Portable models allow for on-site sensor calibration.
Their portability and precision make them valuable tools for professionals requiring accurate temperature calibrations.
