Description
The Pyxis FR-300-PLUS is a magnetic coupling motorized brush flow assembly. It provides an inline mechanical cleaning of the ST-765SS Series bare gold electrode enabling sensor accuracy in challenging industrial cooling and process waters. This unique device enhances the convective mass transport of the oxidizer. Reducing agent analyte to the sensor electrode surface eliminating the need for precision flow control commonly required for other amperometric sensors on the market. The FR-300-PLUS also provides supplemental deactivation protection. Protection of the bare gold electrode for a long life, stability, and precision accuracy in extremely challenging waters. Furthermore, it’s designed for with a variety of alternative Pyxis inline sensors for a range of measurement. These additional sensors are outline in this document.
The FR-300-PLUS contains a ‘chemical injection port’ in the assembly housing. Allowing for the optional injection of cleaning agents at the brush head for industrial waters containing fats, oils and grease. This port may also be used for the addition of Potassium Iodide for measurement of “True Total Chlorine”. The FR-300-PLUS may be operated at a broad range of regulated sample flow from 200 and 800mL per minute with an inlet pressure of <30 psi. The outlet flow line should be diverted to drain or returned to an atmospheric tank /sump within the process itself for reuse.
The FR-300-PLUS comes with a magnetically coupled brush mounted in the liquid end of the flow reservoir. Operational life of the brush is typically 1+ year of service however this is application dependent based on water quality. The brush is held in place via magnetic coupling to the motor shaft for rapid removal and replacement. Brush replacement is outlined in the later sections of this document.
Finally, the FR-300-PLUS requires 24VDC power supply at approximately 2.5watts and can be directly connected to the OEM controller. It also may be powered by the Pyxis Lab outlet power supply adapter accessories available for both 110VAC and 230VAC outlet. (Purchased separately).
