Flex-Sky-CS is a wireless transmitter with an M12 connector for external Pt100 and Pt1000 sensors. The sensor needs to be ordered separately. Thanks to LoRa technology, the transmitter has excellent radio coverage, up to 10 km in open space.
The two-part design of the transmitter allows uninterrupted calibration changes for the measuring module.
The device consists of two parts, a measuring part and a radio part.
