Analytical Sensor Cleaning and Calibration Systems

Automated Cleaning of In-Line Analytical Sensors

Analytical sensor cleaning systems are automated systems that reliably clean and calibrate select sensors to maximize measurement uptime and free personnel for other tasks. Automated cleaning systems are especially beneficial for measurements in aggressive media with high pressures and temperatures. By using these analytical sensor cleaning systems, sensor life can be increased significantly and downtime can be prevented.

FAQs

What is sensor cleaning?

Sensor cleaning is the routine maintenance that has to be performed on an analytical sensor for it to work at its best and maintain a long sensor lifespan. The cleaning requirements for a sensor are directly related to the process conditions.

Why is sensor cleaning important?

Efficient sensor cleaning is important as it prevents fouling of the sensor's diaphragm and build up on the sensor that can effect accurate measurement. Sensor cleaning can substantially increase the lifespan of an analytical sensor. Sensor cleaning is also important because it further enhances process control and safety, and reduces the maintenance burden. Automated sensor cleaning allows staff to work on other important tasks. In addition, regular sensor cleaning and calibration ensures that sensors perform at their best and last longer.

How can you automate analytical sensor cleaning?

Automated cleaning of analytical sensors can be done with METTLER TOLEDO's EasyClean series of automated cleaning systems. These sensor cleaning solutions meets a wide range of process and application needs.

Can sensor cleaning and calibration be done in the sensor housing?

The InTrac series of housings can be operated with the METTLER TOLEDO EasyClean 150 or EasyClean 200 for programmable automatic sensor flushing. InTrac housings can also be operated with EasyClean 500 for programmable, automatic pH sensor cleaning and calibration.

For InDip housings when a high dirt load is foreseen, operation with EasyClean 100 for programmable, automatic sensor rinsing is possible. This reduces plant operator workload for performing manual sensor cleaning and calibration.
