The thermocouple is particularly suitable for applications requiring a stable reference sensor at elevated temperatures.
Its noble metal construction provides the material characteristics required for demanding thermoelectric temperature measurements.
Type S Platinum-Rhodium Thermocouple
The europascal EP-E168 uses a Type S thermocouple measuring element.
Type S thermocouples consist of two different thermoelectric materials:
Positive thermocouple wire: Platinum with 10% rhodium (Pt10Rh)
Negative thermocouple wire: Platinum (Pt)
The thermoelectric voltage generated by these materials depends on the temperature difference between the measuring junction and the reference junction.
The relationship between temperature and thermoelectric voltage is defined by the standardized Type S characteristic according to DIN EN 60584.
Type S thermocouples are widely used as reference sensors in industrial temperature calibration.
Their noble metal construction makes them particularly suitable for measurements at elevated temperatures.
High-Purity Thermocouple Materials
The europascal EP-E168 is manufactured using high-purity thermocouple wires.
The manufacturer specifies the use of materials with the maximum available purity.
High-purity thermocouple materials are important for achieving reliable thermoelectric characteristics.
Impurities and changes in material composition can influence the thermoelectric voltage and introduce measurement errors.
The use of carefully selected materials helps reduce these influences.
This is particularly important when the thermocouple is used as a reference thermometer in calibration applications.
Thermally Treated and Annealed Thermocouple Wires
The thermocouple wires of the europascal EP-E168 are thermally treated and annealed.
This manufacturing process helps reduce thermoelectric inhomogeneity.
Inhomogeneity describes variations in the thermoelectric properties along the thermocouple wires.
These variations can introduce measurement errors when different sections of the thermocouple are exposed to temperature gradients.
Thermal treatment helps improve the consistency of the thermoelectric properties.
This is particularly important for reference thermocouples used in calibration laboratories.
The design of the europascal EP-E168 therefore supports reliable temperature measurements under demanding industrial conditions.
Optimized for Small Immersion Depths
One of the main advantages of the europascal EP-E168 is its design for applications with limited immersion depths.
Conventional reference thermocouples may require relatively deep immersion to minimize heat conduction errors.
However, many industrial dry block calibrators provide only limited calibration well depths.
The europascal EP-E168 features a compact measuring assembly and a thin ceramic protection sheath.
This makes it particularly suitable for temperature calibration applications where the available immersion depth is limited.
The actual required immersion depth depends on the temperature, sensor construction and measurement uncertainty requirements.
For high-accuracy applications, immersion effects must be evaluated as part of the calibration procedure.
Gas-Tight High-Purity Ceramic Protection Sheath
The europascal EP-E168 features a protection sheath manufactured from gas-tight high-purity ceramic.
The ceramic sheath protects the thermocouple wires from the surrounding environment.
Its high-purity construction helps reduce contamination of the noble metal thermocouple materials.
Contamination can influence the thermoelectric properties of platinum and platinum-rhodium wires.
The ceramic protection sheath therefore plays an important role in maintaining reliable measurement performance.
The relatively small sheath diameter also supports fast thermal response.
Fast Thermal Response
The europascal EP-E168 features a thin ceramic protection sheath.
This design reduces the thermal mass of the measuring assembly.
A lower thermal mass can improve the response of the thermocouple to temperature changes.
Fast thermal response is particularly useful during multi-point temperature calibration.
When the calibration temperature changes, the reference thermocouple can respond efficiently to the new temperature conditions.
The actual response time depends on the calibration medium, immersion depth and thermal contact.
Ideal for Dry Block Temperature Calibrators
The europascal EP-E168 was specifically developed for industrial calibration applications.
One important application is the use as a reference thermometer in dry block temperature calibrators.
Dry block calibrators generate controlled temperatures using a heated metal block.
A reference thermometer and the device under test are inserted into suitable calibration wells.
The reference thermometer measures the actual calibration temperature.
The indication of the device under test can then be compared with the reference value.
The compact construction of the europascal EP-E168 makes it particularly suitable for this measurement arrangement.
Its small sheath diameter allows the thermocouple to be used in calibration inserts with relatively small bore diameters.
For accurate comparison calibrations, the reference thermometer and device under test should be positioned in regions with comparable temperatures.
Reference Junction Compensation
Thermocouples measure temperature differences rather than absolute temperatures.
Accurate temperature measurement therefore requires consideration of the reference junction temperature.
The europascal EP-E168 can be used with an external reference junction.
Alternatively, Type S miniature thermocouple connectors can be used.
This provides flexibility when integrating the thermocouple into different measurement systems.
When miniature thermocouple connectors are used, the reference junction compensation must be provided by the connected measurement instrument or another suitable arrangement.
The manufacturer also describes configurations that avoid the use of compensating materials in the connecting cable.
This can help reduce additional thermoelectric effects in demanding measurement applications.
Individual Calibration Parameters
The europascal EP-E168 is designed for use as a calibrated reference thermometer.
The thermocouple characteristic follows DIN EN 60584.
Individual parameters can be determined during calibration.
These parameters describe the relationship between temperature and thermoelectric voltage for the individual thermocouple.
Using individual calibration results can improve measurement accuracy compared with relying exclusively on the standardized thermocouple characteristic.
The appropriate correction values and their uncertainties must be considered when evaluating calibration results.
DAkkS Calibration and Measurement Uncertainty
The europascal EP-E168 can be supplied with DAkkS calibration.
The product datasheet provides measurement uncertainty values for fixed-point and comparison calibration.
Fixed-Point Calibration
| Calibration Temperature | Measurement Uncertainty |
|---|---|
| 0.01 °C | 0.2 K |
| 419.527 °C | 0.5 K |
| 660.323 °C | 0.5 K |
Comparison Calibration
| Temperature Range | Measurement Uncertainty |
|---|---|
| 0 °C to 962 °C | 0.8 K |
| Above 962 °C to 1200 °C | 1.5 K |
These values are taken from the manufacturer’s datasheet.
They describe the stated uncertainties associated with the specified calibration methods and must not be interpreted as the intrinsic accuracy of an uncalibrated thermocouple.
The actual calibration uncertainty and calibration points are documented in the individual calibration certificate.
