IR-M2000 Series - Fiber Type Infrared Moisture Meters

The IR-M2000 Series is fiber type reflection system on-line moisture meters utilizing the infrared absorption of moisture. The sensing part is an optical fiber and can be installed at narrow space and high temperature environment.

Converting capabilities are built into the compact designed detector unit for easy installation and operation. Maximum 99 calibration curves can be stored into memory for many applications. The unit can be used by itself or by combining with personal computers as an analog output and a communication function are provided with.

A setting display unit connectable with maximum 9 detector units can set various kinds of setting items of the detector unit and displays moisture value.

Features

High sensitive optical fiber
The measurement is stable by high sensitive optical fiber. A reflection type optical fiber with lens can measure objects at long measuring distance.
Compact sensor part
The compact and lightweight sensing part using the optical fiber can be used at narrow spaces and places where the direct sighting is difficult.
For location in environment at 150
Any water-cooling in the environment at 150 is not required by the heat-sensitive fiber.
Setting display unit
The setting display unit has a front panel of 96 x 96 mm and can connect with up to 9 sets of the detector unit. The communications interface between the setting display unit and the detector unit is by RS-485.
Protective structure conforming to IP-65
The enclosure of the detector unit and the front panel of the setting display unit conform to IP-65 for severe atmospheric condition.
