Pyxis ST-735 Inline Turbidimeter (Ultra High Range)
Inline turbidimeter, ultra-high range (0-10,000NTU). 4-20mA + RS-485, 7-pin.
Pyxis ST-735 Inline Turbidimeter (Ultra High Range)
The Pyxis ST-735 is an inline turbidimeter built for process and treated water clarity monitoring across an ultra-high measurement range of 0-10,000NTU. It provides continuous readings through both 4-20mA analog and RS-485 Modbus outputs via a 7-pin connector, making it suitable for integration into existing control and SCADA systems.
Description
The Pyxis ST-735 is an inline turbidimeter engineered for continuous clarity monitoring of process and treated water. Mounted directly in the pipeline, it covers an ultra-high measurement range of 0-10,000NTU, making it suited to streams carrying significantly more suspended material than a standard process turbidimeter can read.
Readings are available through both 4-20mA analog and RS-485 Modbus outputs via a single 7-pin connector, so the sensor drops into existing control and SCADA architectures without added wiring complexity. This dual-output design gives plant operators and system integrators flexibility in how the ST-735 reports into their monitoring stack.
It is best suited to facilities that need dependable, real-time visibility into heavily loaded process or treated water lines, where standard-range turbidimeters would saturate or lose accuracy.
Why Use This
Wide Measurement Range
Covers turbidity readings up to 10,000NTU, making it suitable for process streams too heavily loaded for standard turbidimeters.
Flexible Integration
Dual 4-20mA and RS-485 Modbus outputs let it connect to existing analog loops or digital control systems.
Applications
- Process water monitoring — continuous inline clarity tracking in treatment process lines
- Treated water clarity verification — confirms water quality downstream of treatment stages
- Heavily loaded streams — ultra-high 0-10,000NTU range suits process water with high suspended solids
- SCADA/control integration — 4-20mA and Modbus outputs support supervisory monitoring systems
FAQ
What turbidity range does the ST-735 cover?
It measures across an ultra-high range of 0-10,000NTU, designed for process streams that exceed the range of standard process turbidimeters.
How does the ST-735 connect to my control system?
It outputs via both 4-20mA analog and RS-485 Modbus through a single 7-pin connector, allowing integration with existing SCADA or control panels.
Is this sensor installed inline or submerged?
The ST-735 is an inline turbidimeter, mounted directly into the process or treated water line for continuous monitoring rather than submersible tank deployment.
Does it come with mounting hardware?
The standard ST-735 is supplied as a complete unit; a sensor-only variant without the tee assembly kit (ST-735-NT) is also available for installations with existing mounting hardware.
