Ametek CTC1200A Compact
Ametek CTC1200A Shown
The CTC1200A series is a fast dry-block that offers both interchangeable
inserts, the MVI stability circuitry, and calibration software. Both
speed and portability are superior to liquid baths. Dry-block
calibrators do not require hazardous liquids and provide a wide
The CTC1200A series is designed for both on-site and maintenance shop use. The applications are generally critical process control but can vary based on calibration and testing requirements. The user interface is easy and intuitive. One-key-one-function gives you quick access to timesaving features such as the switch test or the auto-stepping function. All models feature a large, backlit LCD display panel, which is easy-to-read even in well-lit areas. Units feature an informative display that provides icons and information regarding the status of the CTC650A and the calibration in-progress.
A rugged, slim-line, aluminum outer casing with die-cast top and bottom protects the CTC1200A of dry-block calibrators. For easy documentation and automatic calibration, all units are delivered with RS232 serial communication and JOFRACAL calibration software.
From the setup menu, the user can select the maximum temperature limit for the calibrator. This function prevents damage to the sensor-under-test caused by the application of excessive temperatures. The feature also aids in reducing drift resulting from extended periods of exposures to high temperatures. This feature can be locked with an access code.
MVI - Improved temperature stability
MVI stands for ’’Mains power Variance Immunity’’. Unstable mains power supplies are a major contributor to on-site calibration inaccuracies. Traditional temperature calibrators often become unstable in production environments where large electrical motors, heating elements, and other devices are periodically cycled on or off. The cycling of supply power can cause the temperature regulator to perform inconsistently leading to both inaccurate readings and unstable temperatures.
The CTC series employ the MVI, thus avoiding such stability problems. The MVI circuitry continuously monitors the supply voltage and ensures a constant energy flow to the heating elements.
Easy-to-use, intuitive operation
All instrument controls may be performed from the front panel. The heat source is positioned away from the panel. This design helps to protect the operator. The main functions on the CTC series are designed with one-key-one-function logic. This means that there are no sub-menus or difficult to remember multiple keystrokes necessary to access primary functions. The easy-to-read, backlit display features dedicated icons, which help in identifying instrument conditions and operational steps.
The CTC series stores the complete instrument setup, including: engineering units, stability criteria, resolution, display contrast, slope (ramp) rate, auto-step settings, and maximum temperature.
The CTC series has a very easy and straightforward procedure for re-calibration/adjustment. There is no need for a screwdriver or PC software. The only thing you need is a reliable reference thermometer.
Place the probe in the calibrator and follow the instructions on the display. Third-party labs and calibration facilities will be able to perform this function if a certificate from an independent source is necessary. Of course, AMETEK can provide you with a traceable calibration certificate from our labs when you require a higher level of confidence.
A bold checkmark on the display indicates that the calibrator has reached the desired set temperature and is stable. The operator may change the stability criteria and establish a greater sense of security in the calibration results. A convenient countdown timer is activated five minutes before the unit reaches stability.
Automatic switch test
Operators can save a lot of time using the automatic thermo switch test function to find values for the ’’Open’’ and ’’Close’’ temperatures. Additionally, this feature displays the hysteresis (deadband) between the two points. The feature ensures a very high repeatability when testing thermo switches. Simply press the ’’SWITCH TEST’’ key to activate the function.
This feature saves manpower. The operator may stay in the control room, or another remote location, monitor-ing the output from the sensor-under-test while the CTC series calibrator is placed in the process and automatically changes the temperature using a programmed step value and rate. Up to 9 different temperature steps may be programmed, including the hold time for each step.
JOFRACAL Calibration Software
The JOFRACAL calibration software ensures easy calibration of RTD´s, thermocouples, transmitters, thermoswithes, pressure gauges and pressure switches. JOFRACAL can be used with Ametek DPC-500, APC, CPC and IPI pres-sure calibrators, all Ametek temperature calibrators, as well as Ametek AMC900, ASC300 multi signal calibrator and ASM-800 signal multi scanner.
JOFRACAL calibration software may also be used for manual
calibrations, as it can be set up to accept manual entry of
calibration data together with other liquid baths, ice points or
dry-block heat sources. The calibration data collected may be stored
on a PC for later recall or analysis. The ITC calibrator stores the
calibration procedure and may be taken out to the process site
without using a personal computer. Once all calibrations are
completed, the data may be uploaded to the JOFRACAL calibration
software for post-processing and printing of certificates. The
calibration data collected may be stored on the personal computer
for later recall or analysis.
