Pyxis ST-588-NT Inline PTSA + Fluorescent Polymer Sensor (No Tee Assembly)

Model:
ST-588-NT
Brand:
Pyxis

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.

Dual-parameter measurement — tracks PTSA inhibitor dose and tagged-polymer dose from one probe
Flexible installation — sold as sensor only, letting sites reuse an existing tee assembly instead of buying a full kit
Dual-parameter measurement — tracks PTSA inhibitor dose and tagged-polymer dose from one probe

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
