ST-500SS-T Tee Ready Stainless Steel PTSA Sensor

The ST-500SS-T sensors is a new 304-stainless steel design allowing insertion and removal of the sensor into the new ST-009 (Stainless Steel) inline tee assembly for high pressure applications up to 290psig. The sensor uses temperature tolerant and humidity resistant optical filters. It can be operated under a wide range of ambient conditions without the need of humidity and temperature regulation. With this design the performance of the ST-500SS-T series can remain stable and consistent for an extended period time.

Furthermore, the Pyxis ST-500SS-T series sensor measures the concentration of PTSA in water. Commonly used as a fluorescent tracer in water treatment applications. This sensor is offered in 304-stainless steel body suited for multiple applications. Including monitoring cooling or process water applications with elevated operating pressures as high as 290psig. The new design allows for easy sensor removal. from the Pyxis ST-009 inline tee assembly for sensor diagnostics, cleaning, and calibration without the need for tools.

Details

The ST-500SS-T is offered in 7-pin cable format and should be used with the Pyxis MA-WB Bluetooth/USB adapter. For those desiring to use the uPyxis 2.0 Mobile or Desktop App. The 4–20mA current output from the sensor may be connected to any controller. That accepts an isolated or non isolated 4–20mA input. The ST-500SS-T sensor is a smart device. In addition to measuring fluorescence, the ST-500SS-T sensor has extra photo-electric components. They monitor 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 well as cleanliness diagnostic data.

The ST-500SS-T sensor is offered in a measurement range of 0-500ppb as PTSA and is easy to calibrate using the uPyxis® 2.0 Mobile or Desktop App. Pyxis Lab standard solutions containing PTSA in the range of 100 to 500 ppb can be used. The calibration standard may also be the water sample itself if the PTSA concentration of the sample is measured and validated by an offline fluorometer. This allows the ST-500SS-T sensor to be calibrated online without being removed from the system.

Diagnostic

The uPyxis® 2.0 App also provides diagnostic information about the ST-500SS-T sensor such as sensor cleanliness factor. It is instrumental in determining if the sensor should be cleaned prior to slope calibration. This diagnostic information can also be available via Modbus RTU. For proper calibration, the ST-500SS-T sensor should be diagnosed for cleanliness via the uPyxis 2.0 APP. Then cleaned using the Pyxis Probe Cleaning Kit (SER-01). After cleaning, the sensor cleanliness should be confirmed via the uPyxis 2.0 APP diagnostics function. Then the user may proceed to sensor zero and slope calibration.

High Performance Sensor for Data Center Cooling

The ST- 500SS is ideal for data center applications, enhanced coolant, and water quality monitoring. Able to handle critical systems like condenser and technology cooling. Designed for seamless integration, the 24V DC-powered sensors feature low power demand (<1.5W), with built in transmitters.  Easy or direct communication with DCS or PLC systems and durable 316L stainless steel construction. Furthermore, the sensor operates under high pressures up to 290 psi. Finally, these features streamline installation, maintenance, and ensure reliable performance in demanding data center environments.
