Measuring point identification
An RFID chip in or on the thermocouple plug ensures wireless transducer identification through the amplifier. RFID technology enables contactless reading and writing of data such as the precise measuring point or the required physical unit (°C or °K). It is written onto the RFID chip via a corresponding RFID transponder in the amplifier.
The chip is reusable and works without batteries.
The MX1609KB-R has a rescaling function. Errors from thermocouples or installation situations can be minimized using a table that converts values from degree C to degree C.
The MX1609KB-R can process maximum 64 value pairs. 14 value pairs can be stored in the TEDS template “Calibration Table" if no additional optional templates are used.
This function delivers the best results when the ambient temperature of the MX1609KB-R, and therefore the temperature of the cold junction, is kept constant.
