The Impact of Drift on Moisture Sensors
Drift in moisture sensors refers to the gradual change in the sensor’s output over time, even when the measured parameter (moisture content) remains constant. This can be due to various factors such as environmental changes, sensor wear and tear, contamination, or calibration issues. The consequences of drift are far-reaching and can result in inaccurate readings, production downtime, compliance issues, and significant financial losses due to product waste and damage.
Consequences of Drift
Inaccurate moisture measurements can have serious implications for product quality and safety. For instance, in food processing, incorrect moisture levels can lead to spoilage or affect the texture and shelf life of the product. Production downtime, resulting from frequent recalibration or sensor replacement, increases operational costs and reduces overall efficiency.
Causes of Drift
Understanding the causes of drift is essential for mitigating it. Environmental factors such as temperature, humidity, and exposure to chemicals can affect sensor performance. Contamination from dirt, dust, or other substances can accumulate on the sensor, altering its readings. Aging and wear of the sensor over time can also lead to inconsistent measurements. Additionally, improper calibration or the need for frequent recalibration contributes significantly to drift.
MoistTech’s Solution to Eliminate Drift
MoistTech’s series of near-infrared moisture sensors is designed to eliminate the issues associated with drifting. These sensors, known as the diamond standard, are calibrated to the exact specifications of the customer’s product through numerous tests. Once introduced to the customer’s product and process, these sensors maintain their data and calibration without requiring monthly or annual maintenance. This ensures that the sensor continues to provide accurate and reliable measurements, even with small changes in the production line such as height and color variations and particle size.
Benefits of Using MoistTech’s Moisture Sensors
Utilizing a moisture control system that maintains its accuracy and repeatability instantly increases the production efficiency of the plant. This allows for the automation of the process to be monitored 100%, reducing downtime and improving overall manufacturing processes. The on-line moisture control system from MoistTech is fast and easy to install on product lines, and once in place, real-time moisture levels can be displayed using an external display or PC. The NIR technology used in these sensors can store up to 50 calibration readings in a single sensor, making it versatile for multiple applications.
Strategic Installation of Moisture Sensors
For optimal efficiency, moisture sensors are recommended to be installed in several locations throughout the process. This includes incoming material lines, before and after the dryer, and before any finishing belts. Such strategic placement ensures continuous monitoring and proactive avoidance of quality control issues.
Conclusion
Eliminating drift in moisture sensors is crucial for maintaining accurate measurements, ensuring product quality, and optimizing production processes. MoistTech’s near-infrared moisture sensors, with their advanced calibration and maintenance-free design, offer a reliable solution to the challenges posed by drift. By incorporating these sensors into their production lines, industries can achieve better outcomes, reduce operational costs, and enhance compliance with regulatory standards.
