Bulk Materials Moisture Gauge

Bulk Materials Moisture Gauge


The PrediktIR bulk materials moisture gauge has been designed to provide high accuracy,  stable and dependable measurement to the bulk materials industry at a cost-effective price. Using near infrared (NIR) non-contact technology, 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 improvements can result in substantial cost reductions and investment payback in a matter of months.

Operating Principle

The PrediktIR works on the principle that water molecules absorb a specific wavelength of infrared(IR) 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.

NDC Technologies Long Experience

NDC Technologies have nearly 40 years of experience in applying NIR technology to their in-process measurement systems. This experience is engineered into every gauge model to ensure that the user can easily employ the gauges without specialist knowledge yet will benefit from the accurate and dependable measurement from day one.

Stable Dependable Measurement

Providing stable measurement is essential in helping our customers improve their process control and maximise efficiency.

Insensitive to Ambient Humidity and Temperature

Designed for purpose and suitable for continuous in-line measurement in harsh industrial applications.

Fast Measurement Rate

Fast measurement rate enables fast process variations to be accurately monitored ensuring the best possible process control.

Process Ready

The simple configuration makes installing single or dual gauge very easy.

Low Cost of Ownership

Long-term stability combined with industry best performance, low installation costs and no routine maintenance requirements guarantee the lowest cost of ownership over PrediktIR’s many years of service.

We found that we were actually losing a lot of money due to not having the correct moisture content in our bricks, so back in January 2019, we decided to look into implementing some non-contact NIR moisture gauges to enable us to monitor this more effectively. We contacted LIMAB UK and installed two NDC Technologies’ PrediktIR moisture gauges in our priority clay prep. area. I am very happy with the PrediktIR gauges and having the ability to constantly monitor the moisture content has massively improved our quality control processes. We were impressed with the evident product knowledge and expertise demonstrated by the team at LIMAB UK and the customer service and aftersales support was great!

Scott Bamford – Technical Manager

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.

Philip Smallridge – Process Improvement and Quality Control

We got a call from John Miller from LIMAB UK back in 2018, just as we were finding our existing moisture gauge was failing. We discussed the possibility of replacing our existing gauge with an NDC gauge and invited John to come in for a site visit and to subsequently quote us for a PrediktIR. We were very impressed with John’s product knowledge and we decided to proceed with the purchase. We have found the PrediktIR to be very reliable and we are very happy with it.
