Automated Sensor Cleaning and Calibration System

Case study on automated sensor cleaning and calibration system
Case study on automated sensor cleaning and calibration system

Many production processes require tight, real-time pH control. Therefore, in-line pH sensors need to be kept clean and calibrated in order that they can provide reliable measurements. If the process contains a high solids content, regular sensor maintenance will be necessary, which puts additional strain on maintenance resources. And if the measurement point is in a health-hazardous environment, staff safety is also at risk.

Sensor cleaning and calibration systems automatically carry out routine sensor maintenance.  This enables reliable process control, can significantly reduce sensor maintenance, and will keep employees safe.

Shandong GuoHong Biotechnology Co., Ltd., located in Shandong Province, China, is a high-end protein product manufacturing enterprise specializing in the production of soybean protein and the development of protein product technology. 

In the manufacturing of its protein products, maintaining precise pH control is of utmost importance to sustain high productivity and product quality. Due to stringent hygiene requirements for food production, employees must wear specialized uniforms and undergo a thorough disinfection process before entering the workshop, making routine maintenance challenging and often resulting in inaccurate pH readings and reduced sensor lifespan, ultimately decreasing overall production output.

To address these challenges, the company implemented METTLER TOLEDO's EasyClean 500 system. The EasyClean 500 performs fully automated, routine maintenance of in-line pH, as well as ORP, and oxygen sensors. The EasyClean 500 significantly reduces the need for manual intervention, as it only requires periodic refilling of cleaning and buffer solutions and occasional sensor exchanges. This can lead to a reduction in maintenance workload by up to 80%.

Read in the application note, about Shandong GuoHong Biotechnology, how EasyClean 500 will keep employees safe and their product quality high.
