ST-500W Inline PTSA Sensor for Industry Standard Tee Assemblies

Description The ST-500W is a stainless steel inline PTSA Pyxis smart sensor uniquely designed to be directly inserted into the WALCHEM® and alternative fluorometer tee assemblies. Since the alternative fluorometers commonly used in the water treatment industry have very similar dimensions as the WALCHEM® tee design, the ST-500W design allows drop-in installation into both designs of inline tee assemblies without the need for plumbing modifications of equipment already in use. The ST-500W is identical in internal design and function as the world-class ST-500 Series inline PTSA sensor platform offering the industry a proprietary design for the direct measurement of PTSA (Pyrenetetrasulfonic Acid, CAS# 59572-10-0) utilizing LED UV light sources (365nm ex/ 410nm em) and is specifically designed for use in industrial cooling water and process water treatment applications. The ST-500W 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-500W offers a combination of 4-20mA as well as RS-485 Modbus output signals in 8-Pin cable format and is Bluetooth Enabled for wireless cleanliness diagnostics and calibration when used with MA-CR or PowerPACK Series Bluetooth Adapters and the uPyxis APP for Mobile or Desktop devices. The ST-500W comes equipped with 1.5m (4.9ft) bulk-head cable with quick adapter as well as 1.5m (4.9ft) flying lead cable with quick adapter, enabling rapid wiring to any microprocessor controller, PLC or DCS system.
