  • Page 11: Mounting Instructions

    The tuning fork must be mounted in a way that takes the arrangement of the filling and emptying apertures into account. To compensate measurement errors caused by the material cone in cylindrical vessels, the sensor must be mounted at a distance of d/6 from the vessel wall. OPTISWITCH 3200 C • Transistor (NPN/PNP)

  • Page 13 Inflowing medium If OPTISWITCH 3200 C is mounted in the filling stream, unwanted false measurement signals can be generated. For this reason, mount OPTISWITCH 3200 C at a position in the vessel where no disturbanc- es, e.g. from filling openings, agitators, etc., can occur. Fig. 5: Inflowing medium Product flow To make sure the tuning fork of OPTISWITCH 3200 C generates as little resistance as possible to product flow, mount the sensor so that the surfaces are parallel to the product movement.
