BEKK SMOOTHNESS TESTER This unit measures the smoothness of surfaces such as printing papers or foils. The GPR offers conventional Bekk conform testing, but also an entirely new method which gives results compatible to Bekk at a much shorter testing time. This is made possible by the adaptive volume chamber with an electronically controlled volume and vacuum. The chamber is located below and directly connected to the polished glass plate so that no valves are needed. A weight of exactly 10kg is loading the sample with the required probe clamping pressure of 100kPa via rubber plate. The vacuum is directly produced in the vacuum chamber and sample clamping is done by an electro mechanical unit, lifting the measuring head against the loading weight. Since the test result depends on climate, the conditioned atmosphere is acquired at every measuring. The new software allows the automatic choice into dependence of the roughness from 5 measurement ranges. The GPR can alternatively as stand-alone equipment or can be used by a PC. The PC control includes statistical, recording and product data base.

The volume chamber connected with the bore in the glass plate is evacuated. The glass plate itself is carrying the weight loaded probe. Between the paper surface and the glass plate air is flowing to the central bore and is causing a raise of pressure in the vacuum chamber. The time between two pressure points is measured and shown on the digital display. With raising smoothness of the paper surface the time becomes longer. The so displayed time is called Bekkseconds and is a direct measurement for the surface smoothness of the probe. The unit is operated fully automatic by pressing the button “start”.
• Five measuring ranges with automatic measuring range adaption • Pressure and time indication on an easy readable display • Integrated statistic function • Remote control using RS-232 as well as transfer measured values to PC or printer • Convenient evaluation software incl. database (record keeping and evaluation) • Automatic zero-setting • In combination with an automatic sample feeder an automatic step-by-step measurement can be done.
