SEACAT furthest from power source 14 Section 2 Description of SEACAT Configuration Options and Plumbing The SEACAT is available with an optional externally mounted submersible pump The pump is required for a SEACAT configured with an optional dissolved oxygen sensor or pumped fluorometer but also provides the following benefits for conductivity data e Improved conductivity response The pump flushes the previously sampled water from the conductivity cell and brings a new water sample quickly into the cell e Improved anti foulant protection Water does not freely flow through the conductivity cell between samples allowing the anti foulant concentration inside the cell to build up Several pump models are available e SBESM miniature pump available in plastic or titanium for pumped conductivity e SBESP plastic or 5T titanium pump a more powerful pump for use if the SEACAT is configured with a dissolved oxygen sensor and or pumped fluorometer In all cases the pump is powered via a cable connected to the standard 2 pin Pump bulkhead connector on the sensor end cap The SEACAT can be configured with a wide range of auxiliary sensors Two standard 6 pin bulkhead connectors on the sensor end cap serve as the input ports for the auxiliary sensor signal voltages and provide power to the sensors Additionally an optional connector can be provided for interfacing with an RS 232 sensor such as an SBE 38 seconda
