The OMM-3000 NIR Online Moisture Meter is a microprocessor controlled infra-red reflectance moisture analyzer.
The latest feature is a new Linearized Base Line algorythm for high signal to noise ratio allowing for high sensitivity and excellent repeatability.
The Instrument can be connected using a standard computer for complete control and calibration or a control unit for simplified in-process control.
With a PC connection: The OMM-3000 can be used as an integrated process control system using the RS-485 interface. Up to 32 Sensor Units can be used and controlled. 10 calibration curves can be stored for each sensor. The software has total control of each sensor including initial setting, calibration, digital and graphical display, diagnostics and more.
New! With a Control Unit Connection: Up to 8 Sensor units can be connected to the control unit. 10 calibration curves can be stored for each sensor.
Sensor Information
The sensor unit uses a dual pbS filtering technique to compensate long term light drift. The double filtering technique has excellent accuracy for a wide range of moisture levels including shiny samples.
3 Filters are used to measure moisture. Two moisture ranges are available from 0 to 40% and from 40 to 90%.
The communication output from the OMM-3000 is via RS-485, it is possible to connect up to 32 units which can be controlled by a single PC. The connection to a PC is via RS-232. The output from the OMM-3000 is via RS-485. An RS-485/232 converter is used to connect multiple unit sensors to the PC.
The unit is fixed by four screws above the sample to keep the distance constant between the sample and the unit. The OMM-3000 unit is suitable for measuring moisture of moving samples because of a reflectance non-contact method.
The optimum sample speed is less than 2-3 meter/sec, and for improved accuracy, the surface of the sample should be as flat as possible.
After installing and calibrating the OMM3000 sensor, the PC can be removed from the system and instead of a PC, an LED display can be used (or Controller) to monitor the value of moisture via the display(option) which is connected to an analog output(4-20mA).
The OMM3000Pro software is installed on a standard PC using Windows 95 or 98) from a standard 1.44Mb Floppy disk.
This control software includes the following functions:
- Moisture Range
- Time Constant(data averaging)
- Alarm range
- Moisture level
- Absorbance level
- Zero Calibration
- Calibration curve preparation (with Automatic linear or non-linear calculations)
- Hold and Preset(Standby mode)
- New OMM Unit(sensor) registration
- Adjustment of analog current output.
