Description

The ST-500 Series inline sensor platform is a proprietary design for 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 offer Pyxis Lab® proprietary algorithms to determine the concentrations of PTSA while measuring sample turbidity and color in highly contaminated waters (ie. ≤150 NTU and 10ppm 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 the MA-WB or PowerPACK Series Bluetooth Adapters and the uPyxis® mobile and desktop app. The ST-500 Series is provided in CPVC with the standard 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.
