Pyxis ST-607 Inline Temperature + Mid Range Chlorine Sensor
Inline temperature + mid-range chlorine (Cl2) sensor (0-400ppm). Dual 4-20mA + RS-485, 7-pin.
Pyxis ST-607 Inline Temperature + Mid Range Chlorine Sensor
The Pyxis ST-607 is an inline, temperature-compensated sensor that measures mid-range chlorine (Cl2) concentration from 0-400ppm. It provides dual 4-20mA analog outputs plus RS-485 Modbus communication through a single 7-pin connector, allowing straightforward integration into chlorine disinfection monitoring and control systems.
Description
The Pyxis ST-607 is an inline, temperature-compensated sensor that measures mid-range chlorine (Cl2) concentration from 0-400ppm. It fills the gap between low-range and high-range chlorine instruments, giving plants a dedicated option for mid-level chlorine disinfection monitoring.
Temperature compensation is built in, so the sensor automatically adjusts its chlorine readings as process water temperature fluctuates, helping maintain measurement accuracy throughout normal operating conditions. Output is delivered through dual 4-20mA analog signals plus RS-485 Modbus, via a single 7-pin connector.
The combined analog and digital output allows the ST-607 to serve both traditional analog control loops and networked PLC/SCADA systems, making it straightforward to integrate into chlorine disinfection monitoring and control systems already in place.
Why Use This
Reliable Mid-Range Chlorine Monitoring
The 0-400ppm range and built-in temperature compensation give accurate Cl2 readings for process chlorination systems even as water conditions vary.
Flexible System Integration
Dual 4-20mA analog outputs combined with RS-485 Modbus let the sensor communicate with both analog controllers and networked control systems through one 7-pin connector.
Applications
- Mid-range chlorine disinfection monitoring — 0-400ppm Cl2 measurement
- Integration into existing chlorine monitoring and control systems
- PLC/SCADA-based dosing control — RS-485 Modbus enables networked automation
