The IR-M2700 Series is fiber optic on-line thickness meters for the measurement of thickness of polymer films and of coating volume of papers and polymer films utilizing the infrared absorption of moisture. The sensing part is a fiber optics 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 fiber optics
  The measurement is stable by high sensitive fiber optics. A reflection type fiber optics with lens can measure objects at long measuring distance.
• Compact sensor part
  The compact and lightweight sensing part using the fiber optics can be used at narrow spaces and places where the direct sighting is difficult.
• For location in environment at 150°C
  Any water-cooling in the environment at 150°C is not required by the heat-sensitive fiber optics.
• 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.
