Wide Temperature Range from 33 °C to 700 °C
The AMETEK RTC-700 covers a temperature range from:
33 °C to 700 °C
This wide temperature range makes the calibrator suitable for demanding industrial and laboratory applications.
Typical applications include the calibration of thermocouples, resistance thermometers, temperature transmitters and industrial temperature sensors.
The RTC-700 is particularly useful in industries where high temperatures must be measured accurately.
These include power generation, chemical processing, petrochemical plants, industrial manufacturing and laboratory temperature metrology.
The maximum temperature of 700 °C allows technicians to calibrate sensors used in high-temperature industrial processes.
High Accuracy Temperature Calibration
The AMETEK RTC-700 provides excellent temperature measurement performance.
The manufacturer specifies an internal reference accuracy of:
±0.30 °C from 33 °C to 660 °C
For the upper temperature range from 660 °C to 700 °C, different accuracy and calibration uncertainty specifications apply.
The external reference sensor measures the temperature directly inside the calibration insert.
This helps reduce the influence of temperature differences between the internal control sensor and the actual calibration location.
The external reference sensor is particularly useful for demanding calibration applications requiring low measurement uncertainty.
Excellent Temperature Stability
Temperature stability is one of the most important characteristics of a high-precision temperature calibrator.
The AMETEK RTC-700 provides excellent stability throughout its temperature range.
The manufacturer specifies:
33 °C to 125 °C: ±0.008 °C
125 °C to 425 °C: ±0.015 °C
425 °C to 700 °C: ±0.020 °C
These values demonstrate the excellent temperature regulation performance of the RTC-700.
High stability reduces temperature fluctuations during calibration and supports repeatable measurement results.
This is particularly important when calibrating precision thermometers and high-accuracy temperature sensors.
Advanced Three-Zone Temperature Control
The AMETEK RTC-700 features an advanced three-zone temperature control system.
Conventional dry-block calibrators may experience temperature gradients caused by heat losses at the upper part of the calibration insert.
These gradients can become more pronounced when several temperature sensors are inserted into the block.
The RTC-700 uses three independently controlled temperature zones to improve temperature distribution throughout the calibration area.
This advanced temperature control technology minimizes axial temperature gradients.
The result is improved temperature homogeneity and more reliable calibration conditions.
The three-zone system is particularly beneficial when calibrating sensors with different diameters and immersion depths.
Dynamic Load Compensation
One of the most important features of the AMETEK JOFRA RTC-700 is the optional Dynamic Load Compensation system.
Dynamic Load Compensation, or DLC, is designed to compensate for the thermal influence of sensors inserted into the calibration block.
When several sensors are inserted into a dry-block calibrator, they can change the temperature distribution within the insert.
This effect is known as thermal loading.
The DLC system uses an additional temperature sensor to monitor the temperature conditions within the calibration insert.
The calibrator adjusts its temperature control to compensate for the thermal influence of the sensors.
This improves temperature homogeneity and reduces measurement errors caused by sensor loading.
Dynamic Load Compensation is particularly useful when calibrating multiple sensors simultaneously.
Excellent Temperature Homogeneity
Temperature homogeneity describes how uniformly temperature is distributed throughout the calibration insert.
The AMETEK RTC-700 combines three-zone temperature control with optional Dynamic Load Compensation.
This technology improves both axial and radial temperature homogeneity.
Axial homogeneity describes the temperature distribution along the immersion depth of the sensor.
Radial homogeneity describes the temperature distribution between different positions within the calibration insert.
Good temperature homogeneity is essential when several sensors are calibrated simultaneously.
It also reduces uncertainty contributions caused by different sensor geometries and immersion depths.
Fast Heating and Cooling
The AMETEK RTC-700 is designed for efficient high-temperature calibration.
The manufacturer specifies the following typical performance:
Heating from 33 °C to 700 °C: 45 minutes
Cooling from 700 °C to 100 °C: 43 minutes
Cooling from 100 °C to 50 °C: 17 minutes
Cooling from 50 °C to 33 °C: 20 minutes
These heating and cooling times allow technicians to perform multi-point calibration procedures efficiently.
The cooling performance is particularly important for high-temperature calibrators because cooling from several hundred degrees Celsius can otherwise require considerable time.
Dry-Block Calibration Technology
The AMETEK RTC-700 uses dry-block temperature calibration technology.
The instrument contains a temperature-controlled metal block with an interchangeable calibration insert.
The temperature sensor under test is inserted into a suitable hole in the insert.
The block is heated to the selected temperature.
After thermal stabilization, the sensor indication can be compared with the reference temperature.
Dry-block calibration provides several practical advantages.
There is no calibration liquid to transport, refill or clean.
The calibration system is suitable for both laboratory and field applications.
Interchangeable inserts allow different sensor diameters to be accommodated.
Interchangeable Calibration Inserts
The AMETEK RTC-700 supports interchangeable calibration inserts.
These inserts are available with different hole diameters and configurations.
Single-hole inserts are suitable for calibrating individual sensors.
Multi-hole inserts allow several temperature sensors to be calibrated simultaneously.
The manufacturer specifies an immersion depth of approximately:
200 mm
This provides suitable immersion conditions for many industrial temperature sensors.
The appropriate insert should be selected according to the sensor diameter, sensor length and required measurement uncertainty.
Good thermal contact between the sensor and insert is important for accurate calibration.
External Reference Sensor Input
The AMETEK RTC-700 B and AMETEK RTC-700 C models include an external reference sensor input.
This allows the calibrator to measure temperature using a compatible STS reference sensor.
A suitable reference sensor for the RTC-700 is the:
STS-200
The external reference sensor provides an independent measurement of the calibration temperature.
This can improve the accuracy of the calibration system.
The external reference sensor is particularly useful for calibration laboratories and demanding industrial applications.
Set Follows True Technology
The AMETEK RTC-700 supports Set Follows True operation when equipped with an appropriate external reference sensor.
In this mode, the external reference sensor measures the actual temperature within the calibration insert.
The calibrator automatically adjusts the block temperature until the external reference sensor reaches the selected setpoint.
This reduces the difference between the displayed reference temperature and the actual temperature at the calibration location.
The function is particularly useful when calibrating temperature sensors with demanding accuracy requirements.
Intelligent Reference Sensors
AMETEK reference sensors feature intelligent connectors that store sensor-specific calibration coefficients.
When connected to a compatible RTC calibrator, the instrument recognizes the sensor and retrieves the stored calibration information.
This simplifies the calibration setup and reduces the risk of incorrect coefficient entry.
The intelligent reference sensor system is particularly useful in laboratories where several reference sensors are used.
Sensor-Under-Test Input
The AMETEK RTC-700 B includes an integrated sensor-under-test input.
This allows the calibrator to measure the electrical output of compatible temperature sensors directly.
Supported measurement functions include resistance, thermocouple signals, voltage and current.
The integrated measurement input simplifies calibration because an additional electrical measuring instrument may not be required.
This is particularly useful for automated calibration procedures.
Automatic Temperature Stepping
The AMETEK RTC-700 includes automatic temperature stepping functions.
Users can define a sequence of temperature setpoints.
The calibrator automatically moves through the programmed temperature steps.
This reduces manual operation and improves the repeatability of calibration procedures.
Automatic temperature stepping is particularly useful when several temperature sensors must be calibrated at identical temperature points.
Automatic Temperature Switch Testing
The AMETEK RTC-700 supports temperature switch testing when equipped with the appropriate measurement configuration.
Temperature switches are used to monitor temperature limits in industrial processes.
During testing, the calibrator increases or decreases the temperature until the switch changes state.
The switching temperature can then be determined.
The reset temperature can also be measured.
The difference between the switching and reset temperatures is the switching hysteresis.
Intuitive Color Display
The AMETEK RTC-700 features a large color display.
The display provides information about:
- Current block temperature
- Selected temperature setpoint
- Temperature stability
- Heating and cooling status
- External reference temperature
- Sensor-under-test readings
- Calibration functions
- Instrument settings
The intuitive interface simplifies daily operation and reduces training requirements.
JofraCal Calibration Software
The AMETEK RTC-700 is compatible with JofraCal calibration software.
JofraCal supports automated calibration procedures and measurement documentation.
The software can be used to control compatible temperature calibrators and organize calibration tasks.
It also supports the documentation of measurement results.
This is particularly useful for calibration laboratories and maintenance departments that require repeatable procedures and structured calibration records.
USB Communication
The AMETEK RTC-700 provides a USB communication interface.
The USB connection enables communication between the calibrator and a computer.
This allows the instrument to be integrated into computer-controlled calibration procedures.
USB communication is particularly useful when using JofraCal software.
