Introducing the ST-587 Inline PTSA + Turbidity Sensor Series | Pyxis Lab®
The Pyxis ST-587 Series inline fluorometer & turbidimeter sensor simultaneously measures the concentration of PTSA (Pyrenetetrasulfonic Acid, CAS# 59572-10-0) and Turbidity in water, utilizing both LED UV and Warm White light sources. PTSA is commonly used as a fluorescent tra
cer in cooling and process water treatment applications where turbidity measurement may be a key performance indicator and critical parameter to
application efficacy. This unique Pyxis sensor platform is offered in both UPVC and 304-stainless steel material depending on application pressures. The SS (stainless steel) version of the sensor platform is ideally suited for
high pressure water systems (up to 100psi, 20 Bar) while the UPVC version of the sensor platform are better suited for application pressures below (100psi, 6.9 Bar). The ST-587 Series sensors can be connected to any device that accepts an isolated or non-isolated 4–20mA input or RS-485 Modbus input. The ST-587 Series sensor is a smart device. In addition to measuring PTSA, the sensor has extra photo-electric components that measure the color and turbidity of the sample water.
This extra feature allows automatic color and turbidity compensation to eliminate interference commonly experienced in real-world applications (as high as 150NTU) as well as in-situ sensor cleanliness diagnostic data.
The ST-587 Series sensors have a short fluidic channel, are very easy to clean and are uniquely designed to overcome shortcomings associated with other fluorometers that have a distal (flat) sensor surface or a long,
narrow fluidic cell. Traditional inline fluorometers are susceptible to color and turbidity interference and fouling and are difficult to properly clean and offer no cleanliness verification.
The Pyxis ST-587 Series sensors use a narrow wavelength band gallium phosphide photodiode and high temperature-tolerant and humidity-resistant optical filters. This combination greatly enhances the robustness
of the probe. It can be operated under a wide range of ambient conditions without the need of humidity and temperature regulation. The performance of the ST-587 Series sensors can be stable and consistent for a long period of time. In addition, the ST-587 series sensors can be easily diagnosed, cleaned, and calibrated using the MA-CR Bluetooth adapter and the uPyxis® mobile or desktop application.
