Contactless online moisture measurement for solids

M-Sens NIR

ENVEA M-Sens NIR is near-infrared (NIR) spectroscopy technology. Utilizing an intelligent software solution the M-Sens NIR delivers instant, accurate and nondestructive, non-contact moisture measurement.

Near Infrared (NIR) spectroscopy uses light transmission and absorption to measure moisture in a sample material.

M-Sens NIR can be use on various type of material, it is a contactless online moisture measurement.

Because NIR penetrates deeper into bulk material than mid-infrared, it provides better, more reliable measurement on a production line.

ACCESSORIES (OPTIONAL)
Temperature Sensor Measures material in 0 – 400 °C range
Opto-Port attachment This stainless steel attachment allows the sensor to adapt to a variety of situations such as screw conveyors and free fall conveyors. Can be ordered with an air blast system for free falling samples.
Dust shield Ensures the sensor will provide consistentand accurate results by preventing the buildup of dust and grime on the lens
OPTO 22 Discrete I/O Output for alarms (LOP, HH, H, L, LL)

In a typical installation, the NIR sensor is mounted over a conveying system (belt, vibratory, pneumatic, etc.) about 25 cm above the product to be measured.

The sensor shines light onto the surface of the product, and after the light hits the product, the calculations to measure the necessary constituents are done. Filters and cell detectors tailored and optimized for your specific application needs are used to zero in on the exact constituent being measured to provide the best results possible.

The readiness and reliability of this data helps you minimize product loss, eliminate the need for unnecessary downtime, and increases your operation’s efficiency, leading to better margins and increased profits.
