Download Model 910-sT System with NIR Sensor OPERATING MANUAL

910-sT MOIST URE MEASURING SYST EM DESCRIPT ION:
The 910-sT System is designed to measure moisture content in processed materials using
Near Infra-Red Reflectance (NIR). This technique has been perfected on instruments
such as the BSP-901, BSP-4000, Smart NIR System, and MCP-1. Moisture Content in
materials such as paper, chemicals, pharmaceuticals, and food products can effectively
be measured using NIR.
The 910-sT NIR Sensor is of a robust anodized aluminum construction, with internal NonVolatile (N-V) memory holding all application operating parameters. The Sensor is sealed
against the ingress of dust and moisture with an equivalent of the NEMA-4 rating.
The 910-sT System addresses the contemporary needs of the process industry in a
number of areas:
1.
Simple application to PLC and other data logging inputs
with an isolated and scaled 4 mA. -> 20 mA. output.
2.
Calibration (linearization) Factors are contained in the Sensor N-V
memory and allow direct outputs scaled in moisture percentage.
3
Automatic IR Signal Gain Control accommodates a wide variety of
products without manual gain adjustment.
4
Isolated Loss-of-Product (LOP) output switch allows determination of lack
of product in the production process. System holds last moisture output
va l u e i n L O P co n d i t i o n .
5
Proprietary IR Pre-Amplifier design with improved IR Signal processing
results in a major increase in signal to noise ratio.
6
Various operating parameters are conveniently entered using the Touch
Screen Display.
The 910-sT Console unit is enclosed in a rugged steel housing, and includes a touch
screen computer for operation and control of the system, and for local moisture
o b se r va t i o n .
The interconnecting cables supplied with the 910-sT System use water and dust proof
military grade connectors for highest reliability. Local wiring is routed through sealed
co r d - g r i p s a s r e q u i r e d f o r t h e i n st a l l a t i o n .
The console unit is vented and fan cooled. The Console is not water proof or splash
proof. A debris filter is provided on the inlet fan and must be changed periodically.
