Pyxis ST-565 Inline HST/HRA Sensor
Inline HST/HRA corrosion inhibitor tracer sensor (0-7.5ppm). 4-20mA + RS-485, 7-pin.
Pyxis ST-565 Inline HST/HRA Sensor
The Pyxis ST-565 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 0-7.5ppm range and communicates via 4-20mA analog output and RS-485 Modbus through a 7-pin connector.
Description
The Pyxis ST-565 is an inline tracer sensor that measures tolyltriazole (TTA) / HST-HRA corrosion inhibitor levels, supporting closed-loop and cooling water treatment programmes. Continuous inline measurement gives operators real-time visibility into corrosion inhibitor dosing, helping confirm that protective chemistries are being maintained at the intended concentration.
It reports concentration across a 0-7.5ppm range and communicates via a 4-20mA analog output and RS-485 Modbus digital signal, both wired through a 7-pin connector for integration with plant control and monitoring equipment.
This sensor is designed for treatment providers and facility operators managing closed-loop or cooling water systems that rely on TTA/HST-HRA corrosion inhibitor chemistries.
Why Use This
Continuous tracer monitoring
Measures tolyltriazole (TTA) / HST-HRA corrosion inhibitor levels in real time across a 0-7.5ppm 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
- Closed-loop water treatment systems — corrosion inhibitor monitoring for protective chemistries
- Cooling water treatment programmes — continuous TTA/HST-HRA tracer monitoring
- Corrosion inhibitor feed verification — confirms dosing at intended levels
- Control system integration — 4-20mA and RS-485 Modbus outputs for automated monitoring
