The ATC-140 features the unique dual-zone heating block - designed for optimum performance and superior temperature homogeneity throughout the block. This new design has a performance equivalent to a liquid temperature bath.

The ATC140 dry-block calibrator may be used to perform fully automatic calibration routines without using an external computer. Use the computer for full upload and download capabilities. Units may also be supplied with inputs for external reference sensors and for sensors-under-test. All ATC calibrators feature RS232 serial communication and standard delivery also includes the JOFRACAL calibration PC software.

Unique temperature performance
The ATC series of calibrators provide precision temperature calibration of sensors; whatever the type or format. This is accomplished through an innovative dual-zone heating technology.

Both the ATC-140 features dual-zone heating technology. Each heating zone is independently controlled for precision temperature calibration. The homogeneity in the lower part is close to that of a laboratory liquid bath. The lower zone ensures optimum heat dissipation throughout the entire calibration zone. The upper zone compensates for heat loss from the sensor-under-test and from the open top. This design also eliminates the need for insulation of the sensors-under-test and makes it possible to calibrate liquid-filled and other mechanical sensors.

Peltier effect
The practical Peltier element (electronic heating pump) consists of many elements of semiconductor material connected electrically in series and thermally in parallel. These thermoelectric elements and their electrical interconnections are mounted between two ceramic plates. The plates serve to mechanically hold the overall structure together and to electrically insulate the individual elements from one another.
 
Features

Details

Set temperature The “Set temperature” feature allows the user to set the exact desired temperature with a resolution of 0.01°.
Instrument setups The ATC series allows the user to store up to nine (9) complete instrument setups. You may store all sorts of information including temperature units, stability criteria, use of external reference sensor, resolution, sensor-under-test (SUT), conversion to temperature, display contrast, etc. The setup may be recalled at any time.
Stability indicator A stability indicator shows when the ATC calibrator has reached the desired temperature and is stable. The user may change the stability criteria, external reference and the sensor-under-test quickly and simply. The stability criteria is the user’s security for a correct calibration. A count-down timer is displayed next to the temperature read-out.
Easy-to-use,
intuitive operation
All instrument settings can be performed from the front panel. The heat source is positioned away from the panel which helps protect the operator.

The keyboard is equipped with five, positive feedback function keys. They correspond to the text in the display and change functionality based on instrument operations. There are also dedicated function keys with permanent functions.

The easy-to-read, backlit display is large with a high contrast that is readable even in high ambient light conditions. The display is easily read from all angles and from a distance without parallax problems. The display also features icons which help identifying instrument conditions and operational steps, making it more intuitive to work with.
Auto-stepping Up to 20 different temperature steps may be programmed including the hold time for each step. Upon completion of an auto step routine, the user can easily read the results for the sensor-under-test. Up to five (5) auto step results are stored.
Liquid bath/
large diameter insert
The ATC-140 is fitted with a 150 mm (5.9 in) deep well with a diameter of 63.5 mm (2.5 in) can be used both as dry-block calibrators and as liquid calibration baths with a magnetic stirrer.

A liquid bath and a dry-block diameter of 63.5 mm (2.5 in), which is twice the size of any other Ametek dry-block calibrator, are both new in the JOFRA product range. With these options it is now possible to calibrate even more temperature sensors at the same time and to calibrate large as well as odd sizes and shapes of sensors, which is not possible to calibrate in the remaining product range.
 
JOFRACAL Calibration Software
The JOFRACAL calibration software ensures easy calibration of RTD´s, thermocouples, transmitters, thermo-switches, pressure gauges and pressure switches. JOFRACAL can be used with Ametek DPC-500, APC, CPC and IPI pressure calibrators, all Ametek temperature calibrators, as well as Ametek AMC900, ASC300 multi signal calibrator and ASM-800 signal multi scanner.

Requirements

Minimum Requirements:
Hardware
  • Intel Pentium II 1.4 GHz Processor
  • 64MB Ram (128MB recommended)
  • Standard VGA (800x600, 256 colors). 1024x768 Recommended
  • CD-Rom Drive for installation of program
  • 1 or 2 free RS-232 serial ports, depending on configurations
Minimum Requirements:
Software
  • Microsoft Windows 98, Microsoft Windows NT 4.0, Microsoft Windows 2000,
  • Microsoft Windows ME, Microsoft Windows XP, Windows Vista\
  • System fonts: MS Sans Serif, Arial
Calibration Software:   View PDF

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.

This then allows the Calibrator:

  • Operate as a stand-alone instrument, using advanced calibration routines without the assistance of a personal computer on site;


  • Prevent unauthorized changes to a calibration routine. Personnel who are not authorized to alter a calibration routine cannot do so.


Calibration of up to 24 sensors with Ametek ASM
Using the Ametek ITC series together with the ASM Advanced Signal Multi-scanner offers a great time-saving automatic solution to calibrate multiple temperature sensors at the same time.

The ASM series is an eight channel scanner controlled by JOFRACAL software on a PC. Up to 3 ASM units can be stacked to calibrate up to 24 sensors at the same time. It can handle signals from 2-, 3- and 4 wire RTD’s, TC’s, transmitters, thermisters, temperature switches and voltage.
