• If the specified medium temperatures are complied with, temperatures that are not
permitted for the respective temperature class will not occur on the equipment.
• With the exception of sensor version CLS15-*1M**, for functional reasons the CLS15
sensors may only be operated up to 120 °C (248 °F) during continuous operation / and up to
140 °C (284 °F) for short periods. The CLS15-*1M** version may only be operated up to
100 °C (212 °F) during continuous operation.
• For functional reasons, the CLS16 sensors may only be operated up to 120 °C (248 °F)
during continuous operation / and up to 150 °C (302 °F) for short periods.
The following connection values are safety limits which may not be exceeded when connecting
to the transmitter:
