T-String

Although the design was driven by the demand for economical temperature measurements in electronic equipment racks and cabinets, the T-String can be used in many different ways. The spacing and length are perfect for a 72” rack. It will measure temperature layers from top to bottom at 1 ft intervals. The T-String is designed to run on a 1-Wire® bus. The T-String itself is made up of six sensors mounted on an 8 ft cable. Each of the DS18B20 sensors has a unique 6-digit address. One end of the cable has a male RJ-45 connector with the first sensor mounted three feet away from the connector. The other five sensors are placed 1 ft apart. There is also a DS2431 memory device on the cable approximately 6 inches from the RJ-45 connector. This is used to identify the position of each sensor on the string, and looks exactly like the sensors. It is NOT a sensor. The T-String will report the sensor closest to the RJ-45 connector first, and then each sensor following it to the end of the string.
