The NEW ST-590 inline sensor measures Fluorescent “Tagged” Polymer (410nm ex / 450nm em) independently. The ST-590 measures for Fluorescent Polymer at a range of 0–20ppm. Like our ST-500, the ST-590 offers internal algorithms that compensate for Color & Turbidity interference. Connect the ST-590 to your controller using dual 4–20mA or RS-485 Modbus output signals.
PTSA & Fluorescent Polymer Combination Monitoring
The ST-590 may be used as a stand-alone monitoring and control sensor for active polymer only or it may be used in conjunction with the Pyxis ST-500 inline PTSA sensor. Providing PTSA (Total Chemical Dosed) and Fluorescent Polymer (Active Polymer Concentration) measurement enables water treatment experts to “dial-in” the system performance to a level not previously attainable in the marketplace with conventional real-time methods.
Through extensive research, Pyxis Lab has mastered this technology and embedded the coding necessary to compensate for color, turbidity and dual fluorophore overlap within the sensors themselves, enabling the user to instantly have “PTSA and Fluorescent Polymer” feed and control using any microprocessor controller, PLC or DCS.
