RBRcoda³ T.D
The RBRcoda³ T.D and RBRcoda³ T.D | deep (Fig. 4) use the thermistor-type temperature sensors and piezoresistive pressure sensors. The pressure sensor is protected by a clear plastic guard.

The depth rating of the RBRcoda³ T.D and RBRcoda³ T.D | deep instruments is determined by the depth rating of the pressure sensor installed. For example, the RBRcoda³ T.D in plastic housing with a 200dbar pressure sensor cannot be used at depths greater than 200m, even though the temperature sensor is rated at 1700m. |
