Bulk Materials Moisture Gauge

Bulk Materials Moisture Gauge


This is the newest moisture gauge of our range, the PrediktIR bulk materials moisture gauge. It has been designed to provide high accuracy,  stable and dependable measurement to the bulk materials industries at a cost effective price. Using near infrared (NIR) non-contact principle it is suitable for many types of continuous processes and will provide real-time moisture measurements that can be used to tightly control the process and warn operators if the process is moving out of specification, thereby increasing yield and improving quality. Efficiency improvement can result in substantial cost reductions and investment payback in a matter of months.

Operating principle

PrediktIR works on the principle that water molecules absorb a specific wavelength of infra red light. By pulsing light at known wavelengths and comparing the absorption rate to an internal reference it is possible to determine exactly by how much each wavelength is being absorbed. Using high speed signal processing the algorithm converts the infrared signals into an output that is proportional to moisture content by means of a calibration curve. The measurement is unaffected by changes in process conditions such as particle size, product height temperature, ambient lighting and humidity changes.

I knew that some of the other Wienerberger sites had already purchased some NDC PrediktIR moisture gauges and I had heard that they were really improving the production processes and quality control procedures. I met up with some of the LIMAB team at ClayTech, and I was immediately impressed with their expertise and what they had to offer. After discussions with NDC Product Specialist, we went ahead and purchased four NDC PrediktIR gauges. The gauges have really helped us to monitor and have greater control of our water input system and we are already getting some really useful data. I would certainly purchase from LIMAB again in the future.
