Pyxis ST-565T Inline TTA Sensor
Inline tolyltriazole (TTA) corrosion inhibitor tracer sensor (0-10ppm). 4-20mA + RS-485, 7-pin.
Pyxis ST-565T Inline TTA Sensor
The Pyxis ST-565T is an inline sensor that measures tolyltriazole (TTA) / HST-HRA corrosion inhibitor levels, supporting closed-loop and cooling water treatment programmes. It reports concentration across a 0-10ppm range and communicates via 4-20mA analog output and RS-485 Modbus through a 7-pin connector.
Description
The Pyxis ST-565T is an inline tracer sensor measuring tolyltriazole (TTA) / HST-HRA corrosion inhibitor levels for closed-loop and cooling water treatment programmes. It provides continuous, real-time monitoring so operators can confirm corrosion inhibitor chemistries are dosing at the correct concentration without manual sampling.
The sensor covers a 0-10ppm range, extending slightly beyond the standard ST-565, and communicates via a 4-20mA analog output and RS-485 Modbus, both wired through a 7-pin connector for integration into control and monitoring systems.
It is suited to treatment providers and facility operators managing cooling water or closed-loop systems that require ongoing corrosion inhibitor feed verification.
Why Use This
Continuous tracer monitoring
Measures tolyltriazole (TTA) / HST-HRA corrosion inhibitor levels in real time across a 0-10ppm 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.
Applications
- Cooling water treatment programmes — continuous corrosion inhibitor tracer monitoring
- Closed-loop water systems — verifies TTA/HST-HRA chemical feed performance
- Corrosion inhibitor feed control — real-time data for dosing adjustment
- Control system integration — 4-20mA and RS-485 Modbus outputs for automated monitoring
