Infrared Temperature Calibration from 50 °C to 500 °C
The Fluke Calibration 9132 provides a controlled infrared calibration target over a temperature range from:
+50 °C to +500 °C
This temperature range covers many important industrial infrared temperature measurement applications.
The instrument is particularly suitable for calibrating infrared thermometers used in manufacturing, maintenance and quality assurance.
The temperature-controlled blackbody target provides a stable thermal radiation source.
An infrared thermometer can be directed toward the target to compare its indicated temperature with the reference temperature.
This allows the measurement error of the infrared thermometer to be determined at different calibration points.
Blackbody Calibration Target
The Fluke Calibration 9132 features a blackbody calibration target with a diameter of:
57 mm (2.25 inches)
The target provides a temperature-controlled surface for non-contact temperature measurements.
Its relatively large diameter allows many handheld infrared thermometers and industrial pyrometers to be calibrated.
For accurate measurements, the infrared thermometer must be positioned so that its complete measurement spot lies within the blackbody target.
The required measurement distance depends on the optical characteristics of the infrared thermometer.
These characteristics are commonly specified by the distance-to-spot ratio.
Target Emissivity of 0.95
The Fluke Calibration 9132 provides a nominal target emissivity of:
ε = 0.95
The manufacturer specifies an emissivity tolerance of:
±0.02 in the spectral range from 8 µm to 14 µm
Emissivity describes how effectively a surface emits thermal radiation compared with an ideal blackbody at the same temperature.
An ideal blackbody has an emissivity of 1.
The Fluke Calibration 9132 provides a controlled radiation source with an emissivity close to this ideal value.
When calibrating infrared thermometers, the emissivity setting of the device under test must be considered.
For instruments with adjustable emissivity, the setting should correspond to the calibration conditions.
The spectral response of the infrared thermometer must also be considered.
Accurate Temperature Control
The Fluke Calibration 9132 provides accurate temperature control throughout its operating range.
The manufacturer specifies:
±0.5 °C at 100 °C
±0.8 °C at 500 °C
These values describe the specified temperature accuracy of the calibration source.
They must not be confused with the measurement uncertainty of a complete infrared thermometer calibration.
The overall calibration uncertainty also depends on the infrared thermometer, measurement distance, target size, emissivity and ambient conditions.
Excellent Temperature Stability
Temperature stability is an important characteristic of an infrared temperature calibrator.
The Fluke Calibration 9132 provides:
±0.1 °C stability at 100 °C
±0.3 °C stability at 500 °C
Good temperature stability helps maintain constant thermal radiation conditions during calibration.
This is particularly important when calibrating infrared thermometers at several temperature points.
The stable blackbody target allows the operator to compare the indication of the device under test with the reference temperature.
Fast Heating and Cooling
The Fluke Calibration 9132 provides efficient heating and cooling performance.
The manufacturer specifies:
Heating from 50 °C to 500 °C: approximately 30 minutes
Cooling from 500 °C to 100 °C: approximately 30 minutes
These values allow calibration procedures to be performed efficiently.
The actual heating and cooling times depend on operating conditions and ambient temperature.
Calibration of Infrared Thermometers
The Fluke Calibration 9132 is designed for calibrating non-contact infrared thermometers.
The calibration procedure is based on comparing the temperature indication of the infrared thermometer with the temperature of a controlled radiation source.
A typical procedure includes selecting the required calibration temperature, allowing the blackbody target to stabilize and positioning the infrared thermometer at a suitable measurement distance.
The complete measurement spot must remain within the target surface.
The temperature indicated by the infrared thermometer is then recorded.
The indication error can be calculated as:
ΔT = T_DUT − T_REF
Where:
- ΔT = Temperature indication error
- T_DUT = Temperature indicated by the infrared thermometer
- T_REF = Reference radiation temperature
The resulting measurement values can be used to evaluate the performance of the infrared thermometer.
For accurate calibration, the reference temperature must be appropriate for the spectral characteristics and emissivity setting of the device under test.
Calibration of Industrial Pyrometers
The Fluke Calibration 9132 is also suitable for calibrating industrial infrared pyrometers.
Pyrometers are commonly used for non-contact temperature measurement in industrial processes.
Typical applications include temperature monitoring of machinery, production equipment and heated components.
The Fluke Calibration 9132 provides a stable radiation target for checking the measurement performance of these instruments.
The pyrometer is aligned with the blackbody target and its indicated temperature is compared with the reference temperature.
This allows measurement deviations to be identified.
The optical alignment, measurement distance and spectral response of the pyrometer must be considered.
Importance of Measurement Distance
Measurement distance is an important factor in infrared temperature calibration.
Infrared thermometers measure thermal radiation from a defined field of view.
The measurement spot generally increases with distance.
If the measurement spot becomes larger than the blackbody target, radiation from the surrounding environment can influence the measurement result.
This can cause significant measurement errors.
The Fluke Calibration 9132 provides a 57 mm target diameter.
The operator must ensure that the infrared thermometer measures only the intended target area.
A suitable measurement distance should be selected according to the optical specifications of the device under test.
Infrared Calibration and Measurement Uncertainty
Infrared temperature calibration requires consideration of several measurement uncertainty contributions.
These include the calibration source accuracy, temperature stability, target emissivity, infrared thermometer resolution and measurement repeatability.
Additional influences may include the spectral response of the infrared thermometer, measurement distance, target size and ambient radiation.
The effective radiation temperature may differ from the physical temperature of the target.
This is particularly important when calibrating infrared thermometers with spectral characteristics that differ from the specified emissivity range.
For high-accuracy calibration, a suitable radiometric reference and an appropriate uncertainty budget are required.
Integrated Reference Well
The Fluke Calibration 9132 includes a reference well positioned behind the blackbody surface.
This allows contact temperature measurements using a suitable temperature probe.
The reference well can be used to check the temperature of the calibration source.
However, the temperature measured by a contact thermometer is not automatically identical to the effective radiation temperature observed by an infrared thermometer.
For accurate infrared calibration, the emissivity and radiometric characteristics of the source must be considered.
RS-232 Communication Interface
The Fluke Calibration 9132 features an integrated RS-232 interface.
This allows the instrument to communicate with a computer.
The interface can be used for remote control and monitoring of temperature setpoints.
The manufacturer specifies compatibility with Fluke Calibration Interface-it software.
This provides additional flexibility for professional calibration laboratories.
Compact and Portable Design
The Fluke Calibration 9132 is designed for portable infrared temperature calibration.
The instrument weighs approximately:
1.8 kg
Its external dimensions are:
102 × 152 × 178 mm
The compact construction makes the instrument suitable for industrial maintenance and field calibration.
The small size allows the Fluke Calibration 9132 to be transported between different measurement locations.
It is also suitable for use on laboratory workbenches where space is limited.
