Description
The Pyxis ST-587 Series inline sensors measures the concentration of PTSA in water. The sensor utilizes both LED UV and WarmWhite light sources. PTSA is commonly used as a fluorescent tracer in cooling and process water treatment applications. Especially applications where turbidity measurement is a critical parameter. This sensor platform is offered in both UPVC and 304 stainless steel material depending on application pressures. The SS version of the sensor platform is ideally suited for high pressure water systems (>100psi / 20 Bar). 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 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. They are very easy to clean and are uniquely designed to overcome problems associated with other fluorometers. For example sensors that have a distal (flat) sensor surface or a long narrow fluidic cell. Traditional inline fluorometers are susceptible to color and turbidity interference. Fouling is also common and difficult to properly clean.
Unique Probe Design
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 theMA-CR Bluetooth/USB adapter and the uPyxis® mobile or desktop application.
