Portable Temperature Calibration from 35 °C to 200 °C
The Fluke Calibration 6102 provides a controlled temperature environment over a range from:
+35 °C to +200 °C
This range covers many important industrial and laboratory temperature calibration applications.
The instrument can be used for the calibration of resistance thermometers, thermocouples, temperature switches and mechanical thermometers.
The liquid bath design provides excellent thermal contact between the calibration medium and the temperature sensors.
This helps reduce measurement errors caused by poor thermal coupling.
The compact construction allows the Fluke Calibration 6102 to be used in calibration laboratories and directly at industrial measurement locations.
Excellent Temperature Stability
Temperature stability is one of the most important characteristics of a calibration bath.
The Fluke Calibration 6102 provides excellent temperature stability over its operating range.
The manufacturer specifies:
±0.02 °C at 100 °C
±0.03 °C at 200 °C
These values apply when using the specified Fluke Calibration 5013 oil.
Good temperature stability is particularly important during comparison calibration.
It allows the reference thermometer and the device under test to be measured under nearly constant temperature conditions.
This helps reduce the uncertainty contribution caused by temporal temperature fluctuations.
High Temperature Uniformity
The Fluke Calibration 6102 provides excellent temperature uniformity.
The manufacturer specifies:
±0.02 °C
Temperature uniformity describes the temperature differences between different positions within the calibration zone.
Good uniformity is particularly important when calibrating multiple temperature sensors simultaneously.
The liquid calibration medium provides effective thermal contact around the immersed probes.
This allows temperature sensors with different geometries to be calibrated under comparable conditions.
Liquid Bath Technology
Unlike a conventional dry-block calibrator, the Fluke Calibration 6102 uses a liquid calibration medium.
The liquid surrounds the immersed temperature sensors.
This provides several advantages.
The calibration medium adapts to different sensor diameters and shapes.
It also reduces problems caused by poor contact between a probe and a calibration insert.
The liquid bath design is particularly useful for short temperature probes and mechanical thermometers.
The Fluke Calibration 6102 therefore offers greater flexibility for certain applications than a conventional dry-block calibrator.
Compact Calibration Chamber
The Fluke Calibration 6102 features a compact calibration chamber.
Chamber depth: 140 mm
Usable working diameter: 48 mm
Nominal chamber diameter: 64 mm
The chamber provides sufficient space for many common temperature sensors.
The usable working diameter allows different sensor configurations to be accommodated.
For high-accuracy calibration, the sensors should be positioned correctly and immersed sufficiently.
The actual measurement uncertainty depends on the sensor geometry and temperature distribution within the bath.
Lightweight and Portable Design
One of the main advantages of the Fluke Calibration 6102 is its compact construction.
The instrument weighs approximately:
4.5 kg including calibration fluid
Its external dimensions are:
140 × 260 × 200 mm
The compact design makes the instrument suitable for portable calibration applications.
The Fluke Calibration 6102 can be transported between different measurement locations without requiring a large transport system.
A specially designed transport lid helps prevent fluid leakage.
The instrument can therefore be transported with the calibration fluid inside when the manufacturer’s transport instructions are followed.
Calibration of Different Temperature Sensors
The Fluke Calibration 6102 is suitable for calibrating many different temperature measuring instruments.
Typical examples include:
- Pt100 resistance thermometers
- Industrial RTD sensors
- Precision platinum resistance thermometers
- Thermocouples
- Liquid-in-glass thermometers
- Bimetallic thermometers
- Temperature switches
- Industrial temperature probes
- Laboratory temperature sensors
The liquid calibration medium provides flexibility when working with different probe geometries.
This is particularly useful for sensors that cannot be inserted into conventional dry-block calibration inserts.
Calibration of Pt100 and RTD Sensors
The Fluke Calibration 6102 is particularly suitable for Pt100 and RTD calibration.
A calibrated reference thermometer and the resistance thermometer under test are immersed in the calibration bath.
After the temperature has stabilized, the reference temperature and the indication of the device under test are recorded.
The indication error is calculated as:
ΔT = T_DUT − T_REF
Where:
- ΔT = Temperature indication error
- T_DUT = Temperature indicated by the device under test
- T_REF = Reference temperature
The resulting measurement values can be used to evaluate the performance of the temperature sensor.
Calibration of Thermocouples
The Fluke Calibration 6102 can also be used for thermocouple calibration.
The thermocouple measuring junction is immersed in the liquid calibration bath.
A suitable reference thermometer measures the actual bath temperature.
The thermoelectric voltage of the thermocouple is measured using a compatible instrument.
The measured voltage can then be compared with the expected thermoelectric voltage for the corresponding thermocouple type.
The measurement uncertainty must consider the reference temperature, thermocouple measurement system and reference junction compensation.
Calibration of Liquid-in-Glass Thermometers
The Fluke Calibration 6102 is particularly useful for calibrating liquid-in-glass thermometers.
These thermometers often have geometries that are difficult to accommodate in dry-block calibrators.
The liquid bath provides a suitable temperature environment around the thermometer bulb.
The indicated temperature can be compared with a calibrated reference thermometer.
This makes the Fluke Calibration 6102 useful for laboratory glass thermometer calibration.
Calibration of Bimetallic Thermometers
Bimetallic thermometers are commonly used in industrial temperature measurement.
Their sensing elements may have relatively large diameters or unusual shapes.
The Fluke Calibration 6102 provides a liquid calibration environment that can accommodate many of these sensors.
The thermometer can be immersed in the bath and compared with a calibrated reference thermometer.
This allows the indication error to be determined at different temperature points.
Integrated Temperature Switch Testing
The Fluke Calibration 6102 includes connections for temperature switch testing.
Temperature switches change their electrical contact state when a defined temperature is reached.
The instrument allows the switching behavior to be evaluated during controlled temperature changes.
This is particularly useful for testing thermostats and temperature-dependent switching devices.
The adjustable temperature ramp rate supports controlled heating and cooling during switch testing.
Eight Programmable Temperature Setpoints
The Fluke Calibration 6102 provides memory for eight temperature setpoints.
This allows frequently used calibration temperatures to be stored.
The operator can select the required temperature without entering the value again.
This feature is particularly useful for repeated calibration procedures.
It simplifies operation and reduces setup time.
Adjustable Temperature Ramp Rate
The Fluke Calibration 6102 provides an adjustable temperature ramp rate.
This allows the temperature to be changed at a controlled rate.
Controlled temperature changes are particularly useful for temperature switch testing.
They can also support calibration procedures requiring gradual temperature transitions.
RS-232 Communication Interface
The Fluke Calibration 6102 features an RS-232 interface.
This allows the instrument to communicate with a computer.
The interface can be used for remote control and automated calibration applications.
The instrument supports Fluke Calibration software solutions such as MET/TEMP II.
This provides additional flexibility for professional calibration laboratories.
Overtemperature Protection
The Fluke Calibration 6102 includes an overtemperature safety cutout.
This function helps protect the instrument against excessive temperatures.
The maximum permissible operating temperature also depends on the selected calibration fluid.
The temperature limits of the fluid must always be considered.
The instrument should not be operated above the boiling point or flash point limits specified for the calibration medium.
Heating and Cooling Performance
The Fluke Calibration 6102 provides efficient heating and cooling within its operating range.
The manufacturer specifies:
Heating from 25 °C to 200 °C: approximately 40 minutes
Cooling from 200 °C to 100 °C: approximately 35 minutes
These values provide an indication of the instrument’s temperature adjustment performance.
The actual heating and cooling times depend on the calibration fluid, ambient conditions and operating configuration.
Suitable Calibration Fluids
The Fluke Calibration 6102 requires a suitable liquid calibration medium.
Fluke Calibration recommends compatible calibration oils for the operating temperature range.
The manufacturer specifies performance values using Fluke Calibration 5013 oil.
The selected fluid must provide suitable thermal properties and remain stable over the required temperature range.
Important considerations include:
- Operating temperature range
- Viscosity
- Thermal stability
- Flash point
- Boiling point
- Chemical compatibility
- Safety requirements
The correct fluid selection is essential for reliable calibration results.
Temperature Comparison Calibration
The Fluke Calibration 6102 is designed for temperature comparison calibration.
A calibrated reference thermometer and the device under test are placed in the same liquid calibration bath.
After thermal equilibrium has been reached, the reference temperature and the indication of the device under test are recorded.
The difference between both values determines the indication error.
For high-accuracy calibration, the measurement uncertainty must include relevant contributions from the reference thermometer, temperature stability, temperature uniformity and measurement conditions.
Use with External Reference Thermometers
The Fluke Calibration 6102 can be used with an external reference thermometer.
This is particularly useful when low measurement uncertainty is required.
The internal temperature controller regulates the bath temperature.
The external reference thermometer measures the actual temperature of the calibration medium.
The reference temperature is then used to evaluate the indication error of the device under test.
Suitable reference thermometers include calibrated platinum resistance thermometers connected to precision thermometer readouts.
