The T-String is an 8-foot sensor string that features 5 DS18B20 sensors spaced at 1-foot intervals. The string ends in an RJ-45 connector 3 feet from the first sensor. This unique temperature sensor also has a DS2431 memory device that identifies the position of each sensor, starting from the sensor closest to the DS2431.
The PVC-coated cable consists of 1 pair of CAT-5E constructions with pin one and pin three of the DS18B20 sensor tied together to form the ground/return line. Pin two is the data line and is brought directly to the connector. The cable is rated for temperatures up to 60°C (140°F).
Each DS18B20 board is mounted onto a small printed circuit board and is covered by our low-pressure molding process. The upper half of the sensor is left uncovered, allowing for response times similar to those of a bare sensor. Our molding process makes the sensors highly weather resistant.
