{"product_id":"dkfb-dgb-ringhalter","title":"DKFB Strain Ring Gauge for Round Tie Bars","description":"\u003cp\u003eStrain measured on a round tie bar without glue and without calibration: the \u003cstrong\u003ering\u003c\/strong\u003e clamps around the bar with two screws and presses foil strain gauges, protected under a stainless steel foil, against the surface so firmly that friction carries the surface strain into the gauges.\u003c\/p\u003e\n\u003cp\u003eIt replaces the bonding a strain gauge otherwise needs, and with it the three quarters of an hour, the chemical cleaning and the grinding – the measuring location only has to be free of loose material such as rust or flaking paint, and a solvent is enough.
