Pyxis ST-500SS Inline Stainless Steel High Pressure PTSA Sensor
Stainless steel high-pressure inline PTSA sensor (0-200ppb). 4-20mA + RS-485, 7-pin.
Pyxis ST-500SS Inline Stainless Steel High Pressure PTSA Sensor
The Pyxis ST-500SS is an inline PTSA fluorometer built with a stainless steel body for high-pressure service, used to track inhibitor dose in fluorescence-traced water treatment programmes. It measures PTSA tracer concentration across a 0-200ppb range and outputs via 4-20mA analog and RS-485 Modbus through a 7-pin connector.
Description
The Pyxis ST-500SS is an inline PTSA fluorometer built with a stainless steel body for high-pressure service, used to track inhibitor dose in fluorescence-traced water treatment programmes.
It measures PTSA tracer concentration across a 0-200ppb range, giving operators a direct, real-time read on whether treatment chemical dosing is holding at target concentration.
Output is via 4-20mA analog and RS-485 Modbus through a 7-pin connector, supporting integration into plant control systems where the sensor will be exposed to elevated line pressure.
Why Use This
Built for High-Pressure Service
A stainless steel body allows this sensor to be used in high-pressure inline installations where a plastic-bodied unit would not be suitable.
Real-Time Inhibitor Tracking
Continuous PTSA fluorescence measurement across a 0-200ppb range gives an accurate read on inhibitor dosing in fluorescence-traced programmes.
Simple Control Integration
4-20mA analog and RS-485 Modbus outputs through a 7-pin connector allow straightforward wiring into a PLC or SCADA system.
Applications
- High-pressure cooling and process water lines — stainless steel body rated for elevated line pressure
- Inhibitor dose tracking in fluorescence-traced treatment programmes
- PLC/SCADA-integrated dosing verification via 4-20mA and Modbus outputs
FAQ
Why choose the stainless steel version over a standard PTSA sensor?
The ST-500SS has a stainless steel body specifically built for high-pressure inline service, making it suited to installations where line pressure exceeds what a standard sensor body is rated for.
What is the measurement range?
It measures PTSA tracer concentration across a 0-200ppb range.
How does it output data to a control system?
Output is via 4-20mA analog and RS-485 Modbus through a 7-pin connector.
Does this sensor include the tee assembly?
The description does not specify a no-tee configuration for this model, distinguishing it from the ST-500-NT variant sold sensor-only.
