Cyclic operation of the transponder at temperatures > 100 °CAt ambient temperatures between +110 °C and +220 °C, care must be taken to ensure that the internal temperature of the SIMATIC RF380T does not exceed the critical threshold of +110 °C. Each heating phase must therefore be followed by a cooling phase. Some limit cycles are listed in the table below. Heating up | Cooling down |
|---|
Temperature | Time | Temperature | Time | 200 °C | 2 h | 25 °C | > 8 h | 200 °C | 1 h | 25 °C | > 2 h | 190 °C | 2 h | 25 °C | > 7 h | 190 °C | 1 h | 25 °C | > 1 h 45 min | 180 °C | 2 h | 25 °C | > 5 h 30 min | 180 °C | 2 h | 25 °C | > 4 h 30 min |
A temperature calculation tool computes the temperature curve for the heat-proof SIMATIC RF380T transponder (see DVD "RFID Systems Software & Documentation", Order No. 6GT2 080-2AA20).
