1.2. Fl LL Installation manual for steel foil stain gauges Surface preperation Please remove any paint with the help of a grinder To install the DMS on a steel beam a grain of 80 100 is quite enough In contrtast to a foil DMS there shouldn t be any scretches on the surface left because the foil is balancing local stress peaks itself Remove rough dust crums with a dry cloth Afterwards you have to clean the surface with a Aceton soaked cloth Move the cloth always from the inside to the outside Avoid a back and forth moving Dont put any paint at the glueing area of the DMS _ Glueing of the DMS Treat the the surface of the steel foil and on the module with Conditioner and Neutralizer by doing so the surfaces are getting started for bonding Put the silicon rubber the aluminium pad and the collet or a magnet with in reach The glue has a processing time of approximetality 3 minutes Dose a small amount of the glue M30 on a clean sheet of paper for example on a oktavheftes Mix the glue with a tooth pick or use the proper mixing duct Put a closed layer of the glue M30 with the help of a tooth pick on one side of the steel foil Press the DMS on the aplication suface and move the DMS 2 3mm under light pressure to squeez out the spare glue on the edges When the DMS scretches on the module then there was enough glue squeezd out Because of the high viscosity stickes the D

MS immediately even on vertikal surfaces Put the silicon cushion AL pad and the collet on the DMS to fix it Practise this step without glue and DMS Bond check After approximately 10 minutes the collet can be removed In your Oktavheft are all glue mixings documented Check if the glue surround the DMS completly There shouldn t be any loose edges Now you can glue the soldering connections ME Mefsysteme GmbH Neuendorfstr 18a D 16761 Hennigsdorf Tel 03302 559 282 Fax 03302 559 141 info me systeme de www me systeme de 1 LL Connection and covering The mantle and the shield of the wire on the DMS which is situated near by the soldering connections can be removed Is the connection wire of the DMS led over rough edges pr long distances the mantel is a mechanic cover to protect the wire The cable can be fixed with super glue On sharp edges or bend angles the cable can be fixed with Barrier E Cover the DMS and the rest of the glue with M Coat D The layer covers the glue edges as well The M Coat D prevents that the connection wires bounces from the soldering connections so it is easyer for you to solder it Do everything step by step a Soldering of the wires of the DMS 1 and fix it with M Coat D b Soldering of the wires of the DMS 2 and fix it with M Coat D c Soldering of the connection wires d Covering of the soldered parts with M Coat D Compare each step with
