VALIDATION SYSTEM WITH THERMOCOUPLES

E-Val Flex von Ellab

VERSATILE REAL TIME SOLUTION FOR THERMAL VALIDATIONS


Thermal validation system for thermocouples type T (Cu / Const) with high measurement accuracy. Designed for the validation of thermal processes, especially steam sterilization.

FLEXIBILITY FOR DIFFERENT VALIDATION APPLICATIONS


The E-Val Flex validation system for validation of thermal processes was designed for applications which must meet the requirements of FDA guidelines and international GMP standards. It is used worldwide in the pharmaceutical industry for validations of:

    • Steam sterilisation in autoclaves
    • CIP-SIP systems
    • Bioreactors
    • Freeze-drying (Lyophilisation)
    • Hot air tunnels / ovens
    • Stability chambers
    • Incubators
    • Washer disinfectors
    • Fridges and freezers

The validation system has 8 or 16 inputs for thermocouples type T and can be extended with additional modules to up to 128 channels.

A digital pressure transmitter as well as a temperature standards can be connected to E-Val Flex

STAND ALONE OPERATION OR IN CONNECTION WITH A PC


Each master module of the thermal validation system is supplied with a license for the validation software ValSuite which is used to to configure the E-Val Flex, to view and store online measurement data and to automate the creation of validation reports.

E-Val Flex can be operated stand-alone or can be connected via Ethernet to a PC.

THERMOCOUPLE WITH “INTELLIGENT” PLUGS

The plugs of all thermocouples are equipped with an EEPROM that contains the serial number and the calibration offsets. Defective thermocouples can thus be replaced without re-calibration of the system.

This technique also allows for an efficient documentation of the thermocouple positions and the historical calibration data in the validation report.

The thermocouples are either sealed and fixed to the plug or there are “E-S” plugs supplied for the installation of your own thermocouples.

HIGH ACCURACY OF THE TEMPERATURE MEASUREMENT FOR VALIDATIONS


Each input has its own cold junction compensation, which minimizes errors caused by variations in ambient temperature. Thanks to this innovative technology, a high accuracy of temperature measurement is achieved.


 Accuracy Comment
E-Val Flex module±0.05 °CAt 23 °C
Thermocouple type T±0.05 °CIn temperature range -50 °C to +150 °C
Total system±0.10 °CAt 23 °C


If a defective thermocouple needs to be replaced, no system calibration is necessary. The thermocouples are pre-calibrated and store the calibration offsets in the ID chip, which guarantees an accuracy of ± 0.05 ° C.
