6.7.1 Thermocouple with TEDS functionality (RFID)
Measuring point identification
An RFID
1)
chip in or on the thermocouple plug ensures wireless transducer identification by
the amplifier. RFID technology enables contactless reading and writing of data, for example
of a specific measuring point or the desired physical unit (5C or 5K). Data is input using
TEDS Editor provided by HBM. Then data is written onto the RFID chip using an appropriate
RFID transponder in the amplifier.
The chip is reusable and works without batteries.
Post−scaling
The MX1609 has a post−scaling function. A table that converts degree
o
C to degree
o
C
enables errors resulting from thermocouples and mounting conditions to be minimized.
The MX1609 processes a maximum of 64 pairs of values. The ”Calibration Table” TEDS
template enables 14 pairs of values to be saved, if no additional optional templates are being
used.
This function provides the best results when the ambient temperature of the MX1609 and
thus the temperature of the cold junction is kept constant.
Conditions for using RFID chips for measuring point identification:
− All channels can read/write via RFID
− The neighboring channel must not be occupied in the MX1609 during writing
− Maximum distance chip to housing: 1 mm
− For self-assembly: Check position of chip on plug

RFID Chip
The chip for measuring point identification is already integrated in the HBM THERMO-MINI.
