Analytical
pH / ORP Analyser
Digital pH sensor and transmitter with built-in diagnostics.
ACCURACY
±0.02 pH
PROTECTION
IP66
01
APPLICATION
Wastewater pH dosing control
pH must be held in a narrow band while dosing chemicals, against fouling and flow changes.
02
RECOMMENDED APPROACH
How it is solved
A digital pH sensor feeds a PID loop that modulates a dosing valve through a smart positioner. Sensor diagnostics warn before fouling affects control.
RECOMMENDED PRINCIPLE
Electrochemical analysis
Ion-selective electrodes and conductivity cells convert chemical activity into potential or current.
How it works →
RECOMMENDED PRINCIPLE
Positioning and actuation
A positioner compares the 4–20 mA setpoint with stem position and drives the actuator until they match.

TYPICAL LOOP
How the measurement fits the process
Instruments sit on the equipment they protect, send their signal to the controller and act through the final element. Demonstration drawing, not a design.
