Thermistor string (RBRconcerto³ Tx)

The RBRconcerto3 Tx is a unique instrument within the standard instrument family as it integrates multiple (12 or 24) temperature sensors in a single chain. The multi-node thermistor strings are made to order and are available in plastic and titanium housings.

To extend the life of your RBRconcerto3 Tx and prevent failures, deploy this instrument over the side of your vessel and never via a winch. Avoid stretching the chain, placing any items on the chain, or bending the chain at radii smaller than 15cm.

Storage

Store the T-string in its shipping crate or a dedicated box, loosely coiled. The smallest bend radius for the T-string cables is 15cm.

Deployment

  1. Remove the T-string out of the box.

  2. Attach the shackle of the mooring line to the clevis of the T-string closest to the instrument.

  3. Attach the instrument to the mooring line with a clamp.

  4. Attach the weight to the clevis at the free end of the string (the opposite of the instrument).

  5. Carefully unspool the T-string on the side of your vessel, weight first.

    The T-string must be supported by the clevis, never by the instrument connector.
