Process Sensors for Liquid Analysis – Reliable Measurement Under Real Process Conditions
Get Stable Measurement Data – Even in Challenging Environments
In many processes, the difficulty is not measuring a parameter – it is maintaining a stable and reliable measurement over time.
Sensors are often exposed to:
- Fouling and coating
- Chemical exposure
- Temperature and pressure variations
This affects accuracy, increases drift, and leads to more frequent maintenance.
Choosing the right sensor technology is essential to ensure that your measurement data remains reliable in daily operation.
Designed for Continuous Measurement in Industrial Processes
Knick sensors are developed for continuous inline measurement of key liquid parameters, including:
- pH
- ORP (redox potential)
- Conductivity
- Dissolved oxygen
The sensors are designed to operate under real process conditions, where stability, durability, and compatibility with maintenance systems are critical.
They can be used as standalone measurement points or as part of a complete system with:
