Factory calibration certificates for analog EtherCAT Terminals

If Beckhoff EtherCAT Terminals are part of a measuring chain and are therefore subject to particular requirements for the reproduction/traceability of measurement results, a calibration certificate for the terminal is issued to the user for quality assurance purposes. As proof of the exact measurement error of the terminal, the certificate permits a more accurate definition of the entire measuring chain and reduces the measurement uncertainty. In the context of the error estimation of a series of measurements, a statement can be made with greater certainty about the accuracy of the measured value.

The standard deviation to the average value is reduced. The calibration certificate is assigned to an individual terminal and can be downloaded on the basis of the unique serial number. It documents the actual, momentary measurement error of the terminal at the time of production and contains important data on the environmental conditions and the testing device employed, the so-called normal.


The following analog EtherCAT measuring terminals are already available with Beckhoff factory calibration certificate. For Availalbility check product page. Further terminals are available on request.
