NDC Technologies PrediktIR sensor offers basic, yet accurate moisture measurements
NDC Technologies, Dayton, OH, says its PrediktIR gauge is for the on-line moisture measurement of wood-sourced products such as woodchips, pellets and sawdust. The PrediktIR gauge serves, for example, biofuel processors looking for a basic on-line moisture measurement solution that is dependable, stable and accurate.
“For years, generic instrumentation suppliers have offered moisture gauges which promise measurements at a low price,” says Andy Grady, Markets Manager for NDC Technologies. “However, in practice, experience has not met expectation: these gauges need regular re-calibration, have poor measurement accuracy and instrument stability which limit their application where process control or even simple monitoring is important.”
The PrediktIR infrared moisture gauge is based on NDC’s proven optical filter technology. It delivers continuous biofuel moisture content information in real time, enabling operators to adjust the airflow to the furnace to optimize combustion and automatically control the drying process, without having to wait for lab sample results.
PrediktIR offers long-term instrument stability and basic, yet accurate, moisture measurements independent of changes in ambient conditions such as lighting, temperature or humidity. The moisture gauge also provides tolerance to physical process changes such as pass height.
NDC says the performance advantages of PrediktIR translate into numerous benefits to processors:
• enhanced product quality and consistency;
PrediktIR is available in two configurations: single-gauge with Operator Interface (OI) and dual-gauge with both instruments connected into a single OI. Applications include single-point measurements, for example after a dryer or conditioner. Dual-gauge applications permit measurements to be made before and after a drying or conditioning process to closely monitor moisture content. PrediktIR can be easily installed in most processes, for example above a conveyor belt or where product is transported in enclosed ducts using NDC’s proprietary PowderVision probe.
PrediktIR can also be equipped with an air purge window to keep optics free of dust and other volatile contaminants.
