1. What is a Temperature Calibrator?
A temperature calibrator is a device that can measure and/or simulate temperature signals for testing and calibrating temperature instruments, such as sensors, probes, transmitters, gauges, and controllers. It is a crucial tool for ensuring that temperature readings are reliable and consistent, especially in critical applications such as industrial processes, scientific research, and medical diagnostics.
2. Types of Temperature Calibrators
● Dry-block calibrators: Portable temperature calibration devices using a dry metal block to heat or cool sensors.
● Liquid baths: Use heated liquids like oil or water for a stable temperature environment. More precise but less portable.
● Infrared calibrators: Use infrared emitters for non-contact thermometer calibration.
● Fixed-point cells: Use phase transitions of pure substances for the highest accuracy, though less portable.
3. How Does a Temperature Calibrator Work?
The calibration process involves:
● Prepare the calibrator: Turn it on and let it stabilize.
● Connect the DUT: Follow the manufacturer’s instructions.
● Set the temperature: Adjust to the desired temperature.
● Wait for stabilization: Allow the DUT to stabilize.
● Record the readings: Note readings from both the calibrator and DUT.
● Calculate the error: Determine the error between readings.
4. How to choose the Right Temperature Calibrator?
Consider these factors:
● Temperature range: Match the range needed for your sensors.
● Accuracy and stability: Ensure close readings to actual temperature and consistent performance.
● Well flexibility: Multiple wells or interchangeable inserts for various sensor sizes.
● Portability: Essential for field calibrations.
● Sensor immersion: Liquid baths for accuracy, dry blocks for portability.
● Throughput: High throughput for quick calibration of multiple sensors.
5. Common Issues and Troubleshooting
Here's a comprehensive guide to common temperature calibrator issues and troubleshooting steps:
Common Issues:
● Temperature Stability: Consistency over time.
● Temperature Uniformity: Consistency within the calibrator’s well.
