Analytical Sensor Cleaning and Calibration Systems

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.

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.

Fully automated sensor rinsing, cleaning, and calibration. This ensures sensors are maintained and calibrated precisely when needed, triggered by time intervals, sensor health status, or inputs from a Distributed Control System (DCS) or Programmable Logic Controller (PLC). This eliminates risks of late or unnecessary calibration, improving process performance, and reducing calibration buffer usage.

By providing fully automated sensor cleaning and calibration, the EasyClean 500 ensures sensors are kept properly maintained and calibrated. This precise and timely maintenance ensures sensor measurement reliability, leading to greater process consistency.

The system is best suited for industries and applications where sensors play a vital role and maintenance demands are high. Key target industries include:

• Petroleum refineries
• Olefin production sites
• Battery chemicals manufacturing
• Mining operations
• Titanium dioxide production

These industries often face challenging conditions that require frequent and reliable sensor cleaning and calibration to ensure optimal sensor performance and process control. In addition, the EasyClean 500 enables analytical parameter monitoring at points previously considered cost prohibitive. This makes it particularly valuable in harsh chemical environments where sensor fouling is common.

The EasyClean 500 significantly reduces labor costs by fully automating the cleaning and calibration of sensors. This automation eliminates the need for frequent manual maintenance, which is time- and labor-intensive.

Yes, the EasyClean 500 can be integrated with our existing transmitters. It supports triggering cleaning and calibration procedures based on time intervals, sensor health status, or inputs from Distributed Control Systems (DCS) or Programmable Logic Controllers (PLC). This flexibility allows it to work with various transmitter setups to ensure sensors are maintained and calibrated precisely when needed. For example, with M400 2-wire transmitters, there are specific ways to implement cleaning functionality either via direct relay signals or through PLC communication, showing the adaptability of EasyClean systems to different transmitter types.
