Pyxis ST-588-NT Inline PTSA + Fluorescent Polymer Sensor (No Tee Assembly)
Inline PTSA + fluorescent tagged-polymer sensor (0-200ppb / 0-20ppm), sensor only, no tee kit. Dual 4-20mA + RS-485, 8-pin.
Pyxis ST-588-NT Inline PTSA + Fluorescent Polymer Sensor (No Tee Assembly)
The Pyxis ST-588-NT is an inline dual-parameter sensor that measures PTSA and fluorescent tagged polymer together in a single probe, across a 0-200ppb / 0-20ppm range. It ships as a sensor only, without the tee assembly kit, and outputs dual 4-20mA analog and RS-485 Modbus signals through an 8-pin connector.
Description
The Pyxis ST-588-NT is an inline dual-parameter sensor that measures PTSA and fluorescent tagged polymer together in a single probe, across a 0-200ppb / 0-20ppm range.
It ships as a sensor only, without the tee assembly kit, suiting sites that already have compatible tee hardware installed and need a replacement or additional sensor.
Output is dual 4-20mA analog and RS-485 Modbus through an 8-pin connector, for integration with plant control systems.
Why Use This
Two Tracers, One Probe
Measuring PTSA and fluorescent tagged polymer together reduces the number of insertion points needed on the process line.
Cost-Effective for Existing Installations
Supplied as a sensor only, it lets sites with an existing tee assembly add or replace a sensor without purchasing a full mounting kit.
Standard Control Integration
Dual 4-20mA analog and RS-485 Modbus outputs through an 8-pin connector allow straightforward wiring into a PLC or SCADA system.
Applications
- Sites with existing tee hardware needing a sensor-only replacement
- Combined PTSA and tagged-polymer dosing verification
- PLC/SCADA-integrated dual-parameter monitoring
