Pyxis ST-500-NT Inline PTSA Sensor (No Tee Assembly)
Inline PTSA sensor (0-200ppb), sensor only, no tee assembly kit included. 4-20mA + RS-485, 7-pin.
Pyxis ST-500-NT Inline PTSA Sensor (No Tee Assembly)
The Pyxis ST-500-NT is an inline PTSA fluorometer used to track inhibitor dose in fluorescence-traced water treatment programmes, with a measurement range of 0-200ppb. It ships as a sensor only, without the tee assembly kit, for sites that already have compatible tee hardware installed. Output is via 4-20mA analog and RS-485 Modbus through a 7-pin connector for integration with plant control systems.
Description
The Pyxis ST-500-NT is an inline PTSA fluorometer used to track inhibitor dose in fluorescence-traced water treatment programmes, with a measurement range of 0-200ppb.
It ships as a sensor only, without the tee assembly kit, making it the right choice for sites that already have compatible tee hardware installed and simply need a replacement or additional sensor.
Output is via 4-20mA analog and RS-485 Modbus through a 7-pin connector, allowing straightforward integration with existing plant control systems for continuous inhibitor dose verification.
Why Use This
Real-Time Inhibitor Tracking
The PTSA fluorometer continuously measures tracer concentration from 0-200ppb, giving an accurate, real-time read on inhibitor dosing in fluorescence-traced programmes.
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.
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
- Cooling water inhibitor dose verification — fluorescence tracing confirms treatment chemical is reaching target concentration
- Sites with existing tee hardware — sensor-only format avoids paying for a duplicate tee assembly
- PLC/SCADA-integrated dosing control — 4-20mA and Modbus outputs support automated dose adjustment
FAQ
Does this sensor come with a tee assembly for installation?
No. The ST-500-NT is sold as a sensor only, without the tee assembly kit, for sites that already have compatible tee hardware installed.
What is the measurement range of this sensor?
It measures PTSA tracer concentration across a 0-200ppb range.
How does the sensor output connect to my control system?
It outputs via 4-20mA analog and RS-485 Modbus through a 7-pin connector for integration with plant control systems.
What is this sensor used for?
It tracks inhibitor dose in fluorescence-traced water treatment programmes by measuring PTSA tracer concentration in the water.
