2. Technical Information Description Series TB300 torque tube liquid level instruments utilize the buoyancy exerted on a displacer when immersed in a liquid. The buoyancy on the displacer is proportional to the liquid level and operates on an elastic torque tube which, transforming the applied force in a rotary movement, operates the magnet and consequently the electronic transmitter. - Page 10 Tecnical data Torque tube 0÷ 356 mm (14") 0÷ 508 mm (20") 0÷ 610 mm (24") 0÷ 813 mm (32") Standard ranges of measurement in mm 0÷1219 mm (48") 0÷1524 mm (60") 0÷1829 mm (72") 0÷2134 mm (84") (or inches) 0÷2439 mm (96") 0÷2743 mm (108") 0÷3048 mm (120")
- Page 11 Mounting The level transmitter TB300 are described in detail in the data sheet 7E.300. They are available for external mounting (displacer cage type) or for top or side mounting (displacer internal to process, without cage) The mounting on the tank is achieved by means of flanged connections and the various styles are shown in figure 4.

- Page 15 Avoid routing signal wiring close to power cables or switching equipment. The TB300 is protected against reverse polarity, and can withstand ±50 mA without damage. The TB300 connection could be done conform the figure 9 and 10. For proper operation, the Hand-Held Terminal requires a minimum load of 250 Ohm between it and the power supply.
- Page 16 Connection of the TB300 in multidrop configuration should be done as in Fig. 10. Note that a ma- ximum of 15 transmitter can be connected on the same line and that they should be connected in parallel. Take care to the power supply as well, when many transmitters are connected on the same line.
- Page 17 3. Commissioning The transmitter is calibrated in the factory, nevertheles ot is possible to recalibrate it in the field through the "simple adjusting" procedure. There are two orifices on the Transmitter , under the nameplate, identified by "S" and "Z" respectively, which provide access to two magnetic switches actuated by means of a magnetic tool (Refer to Fig.12).
