AccuProbe Model 1000 Series NDC Infrared Engineering logo

A Versatile, Low-Cost, Fixed Position Sensor and Display

The NDC Infrared Model 1000 Series AccuProbe provides basic, accurate, continuous, and reliable basis weight or thickness measurement of plastic sheet, film, coatings, nonwovens or composite web products. A small measurement probe mounted on one side of the web is interfaced to a compact display unit. This panel-mounted electronic control unit (ECU) displays the instantaneous basis weight or thickness measurement directly in engineering units, i.e., oz/yd2, grams/m2, mils, etc. Other functions include data communication to host systems, high/low limit alarms, shutter stauts and multi-level passcode protection.

Theory of Operation
The measurement technique is based upon the Compton Photon Backscatter principle (commonly called gamma backscatter). A low activity radioisotope in the probe emits low-energy gamma rays which are collimated and directed at the measured material. These gamma rays interact with the product, lose energy, and are then scattered back toward the detector in direct proportion to the mass of the measured material. An efficient scintillation crystal/photomultiplier detector converts the backscattered gamma energy to photons of light and ultimately to a digital signal which is directly related to product weight/area or thickness (assumes contact density). Unique to the gamma backscatter sensor is its insensitivity to product color, composition or opacity changes.

Features
  • One-sided contact or non-contact fixed position measurement.
  • Continuous digital readout of weight/area or thickness
  • Insensitive to changes in product color, composition, or opacity
  • Easy to set-up and operate
  • Serial communication RS232, RS485
  • 4-20 mA (non-isolated) analog output
  • Programmable recipes for targets, calibration parameters, alarm limits, etc.
  • Simple installation in tight spaces
  • Reliable, easy to maintain

Benefits
  • Improve product quality and uniformity
  • Reduce raw material usage
  • Reduce scrap and product change times
  • Improve production efficiency
