Pyxis ST-601 Inline Temperature + ClO2 Sensor
Inline temperature + chlorine dioxide sensor (0-3,500ppm). Dual 4-20mA + RS-485, 7-pin.
Pyxis ST-601 Inline Temperature + ClO2 Sensor
The Pyxis ST-601 is an inline sensor that measures temperature-compensated chlorine dioxide (ClO2) concentration, supporting chlorine dioxide disinfection monitoring. It reports concentration across a 0-3,500ppm range and communicates via 4-20mA analog output and RS-485 Modbus through a 7-pin connector.
Description
The Pyxis ST-601 is an inline sensor that measures temperature-compensated chlorine dioxide (ClO2) concentration, supporting chlorine dioxide disinfection monitoring in water treatment systems. Temperature compensation helps maintain accurate readings as process conditions change, giving operators reliable visibility into ClO2 feed performance.
It reports concentration across a wide 0-3,500ppm range and provides dual 4-20mA analog outputs plus RS-485 Modbus communication, all wired through a 7-pin connector, enabling the sensor to feed two independent control or monitoring points.
It is designed for facilities and treatment providers using chlorine dioxide for disinfection who need continuous, temperature-compensated feed verification tied into their control systems.
Why Use This
Continuous tracer monitoring
Measures temperature-compensated chlorine dioxide (ClO2) concentration in real time across a 0-3,500ppm 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
- Chlorine dioxide disinfection monitoring — temperature-compensated ClO2 tracking
- Water treatment disinfection programmes — continuous inline feed verification
- Dual-point control integration — independent 4-20mA outputs for multiple monitoring points
- Control system integration — RS-485 Modbus and analog outputs for SCADA/PLC feed
