General information
The model CED7000 process calibrator combines the capabilities of a signal, temperature and pressure calibrator in a single instrument. With the efficiency of a laboratory instrument, an additional isolated measuring channel and optional external pressure modules, the CED7000 is perfect for the widest range of calibration tasks.
Extensive application possibilities
The CED7000 has a wide range of application options. It can be used for calibration in industry (laboratory, production, workshops) and in laboratories and institutes.
Efficiency
The signal calibration capability of the CED7000 includes current, voltage and resistance. In the thermocouple and resistance thermometer mode, the unit offers a selection between 13 different thermocouples and 9 different resistance thermometers.
For pressure measurement, an external pressure sensor is required. The best results are achieved by using the CPT6100 series. The accuracy and the resolution are dependent on the respective pressure sensor. The fully isolated measuring channel enables the calibration of transmitters. The CED7000 thus combines the two functions, measuring and simulation, in one instrument. The CED7000 is very easy to use. It supports direct entry using keyboard or cursor keys. The CED7000 can be controlled via PC using RS-232, IEEE-488 or optionally a USB connection.
Certified accuracy
Every process calibrator CED7000 is provided with a factory calibration certificate which certificates the accuracy of the instrument. On request, we can provide a DKD/DAkkS calibration certificate for this instrument.
