PTSA Inline Sensor
For Industrial Cooling & Membrane Water Applications
The ST-500 Series inline sensor platform is a proprietary design for the direct measurement of PTSA (Pyrenetetrasulfonic Acid, CAS# 59572-10-0) utilizing LED UV light sources (365nm ex/ 410nm em) for use in industrial cooling water and process treatment applications.
The ST-500 Series offers Pyxis proprietary algorithms to determine the concentrations of PTSA while measuring sample turbidity and color in highly contaminated waters (ie. <150 NTU and 10 ppm Fe) for internal compensation. The ST-500 Series offers a combination of 4-20mA as well as RS-485 Modbus output signals and is Bluetooth Enabled for wireless cleanliness diagnostics and calibration when used with MA-WB or PowerPACK Series Bluetooth Adapters and the uPyxis APP for Mobile or Desktop devices. The ST-500 Series is provided in CPVC with the standard Pyxis ST-001 inline 3⁄4” FNPT Tee assembly, 5-foot bulk-head cable with quick adapter and 1.5ft flying lead cable with quick adapter, enabling rapid wiring to any microprocessor controller, PLC or DCS system. The ST-500SS is offered in 304L Stainless Steel with 3⁄4” FNPT ports for high pressure applications.
