Ametek ATC157A Advanced Temperature
Ametek ATC157A Shown
The Ametek ATC-157 all 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 ATC-157 features the widest temperature range for a cooling dry-block on the market today.
Each ATC 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 tempera-ture calibration of sensors; whatever the type or format. This is accomplished through an innovative dual-zone heating technology.
The Ametek ATC 157 features a 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.
ATC heating and cooling models
The models with both heating and cooling capabilities feature the Peltier element multi-stage-technology. This both improves efficiency and extends the life of the »electronic heat pump«. The Ametek ATC-157 offers a typical differential temperature of 68°C (122° F) below the ambient temperature.
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.
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.
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 ATC 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.
The “Set temperature” feature allows the user to set the exact desired temperature with a resolution of 0.01°.
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.
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.
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.
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 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.
