Ideal for Demanding Calibration Applications
The AMETEK CTC-1200 is designed for applications where accurate temperature measurements are essential at elevated temperatures.
Many industrial processes operate at temperatures significantly above the operating range of conventional temperature calibrators.
Typical examples include industrial furnaces, heat treatment systems, metal processing equipment and thermal production processes.
Temperature sensors used in these applications are exposed to demanding operating conditions.
Over time, mechanical stress, contamination and thermal aging can cause measurement deviations.
Regular calibration helps identify these deviations and maintain reliable temperature measurements.
The AMETEK CTC-1200 provides a controlled high-temperature source for checking these sensors.
Its compact construction allows the instrument to be used in calibration laboratories and suitable industrial environments.
Temperature Range from 300 °C to 1205 °C
The AMETEK CTC-1200 provides a temperature calibration range of:
300 °C to 1205 °C
This wide high-temperature range makes the instrument suitable for numerous industrial applications.
Typical calibration temperatures include:
300 °C, 400 °C, 500 °C, 600 °C, 700 °C, 800 °C, 900 °C, 1000 °C, 1100 °C and 1200 °C.
The maximum operating temperature of 1205 °C allows calibration of thermocouples used in demanding industrial processes.
The minimum calibration temperature is 300 °C.
Consequently, the instrument is intended for high-temperature applications rather than general-purpose calibration near ambient temperature.
For accurate results, the temperature sensor must be inserted correctly and sufficient stabilization time must be allowed.
Temperature Accuracy of ±2.0 °C
The manufacturer specifies an accuracy of:
±2.0 °C
This specification refers to the internal temperature reference under the manufacturer’s defined conditions.
The accuracy of the calibrator must be distinguished from its temperature stability.
For demanding comparison calibrations, a suitable external reference thermometer can be used.
The external reference measures the temperature in the calibration insert and allows the device under test to be compared with a traceable reference.
The uncertainty of the complete calibration system depends on the reference thermometer, measurement instrument, temperature distribution and calibration procedure.
Excellent Temperature Stability
The AMETEK CTC-1200 provides excellent temperature stability.
The manufacturer specifies:
±0.1 °C
Temperature stability describes the variation of the calibration temperature over time under defined operating conditions.
Stable temperature conditions are particularly important when calibrating thermocouples.
At high temperatures, even small temperature fluctuations can influence the measured thermoelectric voltage.
The AMETEK CTC-1200 provides a stable temperature environment for comparison measurements.
For demanding calibration procedures, the temperature stability should be considered when evaluating the measurement uncertainty.
Fast Heating Performance
The AMETEK CTC-1200 provides efficient heating performance.
The manufacturer specifies a typical heating time of:
45 minutes from 23 °C to 1205 °C
This allows the calibrator to reach its maximum operating temperature within a relatively short time.
Fast heating helps reduce waiting periods during calibration procedures.
It is particularly useful when performing calibrations at several high-temperature points.
The actual heating time depends on ambient conditions, sensor loading and the selected calibration insert.
Controlled Cooling Performance
The AMETEK CTC-1200 also provides controlled cooling.
The manufacturer specifies a typical cooling time of:
120 minutes from 1205 °C to 300 °C
The cooling process is important when performing calibration sequences with decreasing temperatures.
Such procedures may be used to investigate sensor hysteresis or repeatability.
The calibration block and inserts remain extremely hot after operation.
Appropriate cooling time must be allowed before removing inserts or transporting the instrument.
Temperature Stabilization
The AMETEK CTC-1200 has a typical stabilization time of:
20 minutes
This value describes the stabilization behavior under the manufacturer’s specified conditions.
The temperature sensor itself may require additional time to reach thermal equilibrium.
The required stabilization time depends on sensor diameter, construction, immersion depth and thermal response.
For demanding applications, the stability of the complete measurement system should be verified before recording calibration results.
Interchangeable Calibration Inserts
The AMETEK CTC-1200 uses interchangeable calibration inserts.
These allow temperature sensors with different diameters to be accommodated within the calibration block.
The manufacturer specifies a calibration well diameter of:
27 mm
The insert dimensions are:
25 mm diameter × 155 mm length
Different insert configurations can be selected according to the sensor dimensions.
The appropriate insert should provide suitable thermal contact between the calibration block and the sensor.
Excessive clearance can increase temperature differences and contribute to measurement uncertainty.
At high temperatures, the thermal expansion of the sensor and insert must also be considered.
Immersion Depth of 110 mm
The AMETEK CTC-1200 provides an immersion depth of:
110 mm
Sufficient immersion depth is essential for accurate temperature calibration.
At elevated temperatures, heat conduction along the sensor stem can cause significant measurement errors.
The required immersion depth depends on the sensor construction and sensing element position.
For high-accuracy calibration, the influence of heat conduction should be evaluated.
This is particularly important for thermocouples with long sensing elements or large protective sheaths.
Calibration of Thermocouples
The AMETEK CTC-1200 is particularly suitable for thermocouple calibration.
Thermocouples are widely used in high-temperature industrial processes.
Typical applications include:
- Industrial furnace temperature measurement
- Heat treatment processes
- Metal processing
- Thermal production systems
- Power generation
- High-temperature process monitoring
The thermocouple is inserted into a suitable calibration insert.
The calibrator generates a controlled temperature.
The thermocouple voltage is measured using a suitable external instrument.
The measured temperature can then be compared with the reference temperature.
For accurate thermocouple calibration, reference junction compensation must be considered.
Calibration of High-Temperature Sensors
The AMETEK CTC-1200 can also be used for checking other suitable high-temperature sensors.
The sensor must be mechanically and thermally compatible with the calibration insert.
The maximum permissible operating temperature of the sensor must not be exceeded.
For sensors with large protective sheaths, special attention must be paid to immersion depth and thermal contact.
The instrument is particularly useful for checking temperature sensors removed from industrial equipment during maintenance.
Automatic Temperature Stepping
The AMETEK CTC-1200 supports automatic temperature stepping.
This function allows predefined temperature setpoints to be approached automatically.
Automatic temperature stepping helps simplify repetitive calibration procedures.
It can reduce manual intervention when performing calibrations at several temperatures.
The function is particularly useful for industrial maintenance and routine calibration applications.
Temperature Switch Testing
The AMETEK CTC-1200 provides a temperature switch test function.
Temperature switches are used in industrial control and safety systems.
They activate or deactivate electrical contacts when a defined temperature is reached.
The calibrator can generate controlled temperature changes while monitoring a suitable potential-free switch contact.
This allows switching points to be determined.
The temperature switch must not be connected to an external voltage source during testing.
RS-232 Communication Interface
The AMETEK CTC-1200 features an integrated RS-232 communication interface.
This interface allows the calibrator to communicate with compatible external equipment.
The instrument can be integrated into computer-assisted calibration procedures.
Remote communication is particularly useful for repetitive calibration tasks.
The available communication commands and settings are described in the manufacturer’s operating instructions.
Mains Voltage Immunity
The AMETEK CTC-1200 incorporates Mains Voltage Immunity technology.
This technology helps reduce the influence of fluctuations in the electrical power supply.
Stable temperature control is particularly important in industrial environments where mains voltage variations may occur.
The system supports consistent calibration performance under the specified operating conditions.
Compact and Portable Construction
The AMETEK CTC-1200 combines high-temperature calibration capability with compact construction.
The manufacturer specifies dimensions of:
241 × 139 × 408 mm
The instrument weighs approximately:
12 kg
This makes the calibrator suitable for transportation between different measurement locations.
The compact design also requires relatively little space in a calibration laboratory.
For safe transportation, the instrument must be allowed to cool sufficiently after operation.
