Pyxis ST-525SS-HR Inline Stainless Steel High Range Fluorescein Sensor

Model:
ST-525SS-HR
Brand:
Pyxis

The Pyxis ST-525SS-HR is an inline sensor that measures dye-tagged (fluorescein) treatment chemical dosing, supporting treatment chemical feed. It reports concentration across a 0-500ppb range and communicates via 4-20mA analog output and RS-485 Modbus through a 7-pin connector. Its stainless steel body is built for high-pressure process line installations.

Description

The Pyxis ST-525SS-HR combines a high-range fluorescein tracer measurement with a stainless steel body rated for high-pressure process line installation. It tracks dye-tagged treatment chemical dosing across a 0-500ppb range, extending detection well beyond the standard sensor’s ceiling for higher-concentration treatment programs.

The stainless steel construction allows the sensor to be installed in demanding, high-pressure process water systems where a standard housing would not be appropriate. Readings are available through a 4-20mA analog output and RS-485 Modbus, both wired through a 7-pin connector.

This sensor suits treatment providers running higher-concentration dye-tagged chemistries on high-pressure boiler or process water lines who need continuous, real-time feed verification.

Why Use This

Continuous tracer monitoring

Measures dye-tagged (fluorescein) treatment chemical dosing in real time across a 0-500ppb range, giving operators direct visibility into treatment chemical performance.

Easy control system integration

Dual 4-20mA analog and RS-485 Modbus outputs through a 7-pin connector let the sensor feed data straight into existing SCADA or controller setups.

Built for high-pressure lines

The stainless steel housing withstands high-pressure process water service where standard sensor bodies would not be suitable.

Applications

  • High-pressure process water lines — stainless steel body for demanding service conditions
  • Higher-concentration dye-tagged treatment programs — extended range up to 500ppb
  • Treatment chemical feed verification — continuous inline monitoring of dosing performance
  • Control system integration — 4-20mA and RS-485 Modbus outputs for automated feed control
