To determine moisture on a continuous basis, the NIR Moisture and Control System uses the principle of comparing reflected energy at two near-infrared (NIR) wavelengths. 

A stabilized infrared source is focused on the material to be measured, and reflected energy is filtered at two different wavelengths—one calibrated specifically for moisture and the other as a reference. 

The ratio of the two signals is derived electronically, and the resulting moisture content is presented on the digital display. This non-contact NIR technique can measure near-surface moisture in a wide range of applications.
The Smart II System also includes S2Comm communication software, which can be used to display as many as four moisture meter outputs on any PC monitor.
•Stores 5 separate 3-point
(high-mid-low) calibration tables for multiple products

•Complete Digital Processing provides push button, drift-free calibration

•Nonvolatile Battery Backed Memory for safe storage of calibration data

•Many types of digital outputs available

•LED display provides direct read-out in percent moisture content
•The console enclosure provides a touch key board and detailed operating legend for easy data entry

•Optional Security Pass Code prevents unauthorized access to the calibration data

•Loss of Product detection shows when there is no product under sensor

•Analog output provides standard 4-20mA output proportional to moisture for interfacing to industrial control systems

•Programmable Alarm Solid
State Relays assure warning alarm when moisture set point is reached or Loss of Product occurs

•Sample-on-Command feature provides for gated readings of batch operations

•Programmable Smoothing Function reduces undesired output fluctuations by averaging readings

•For Continuous On-Line Analysis, PID Closed Loop Feed-back Control, or in the Lab for Static Testing

•A System consists of three components: the BSP-901
Wall Mounted Console and a NIR Sensor with a power box or a RF Sensor with an
