    4 Mounting Fig. 2: Measures against moisture ingress Transport Do not hold OPTISWITCH 3200 C on the vibrating element. Espe- cially with flange and tube versions, the sensor can be damaged by the weight of the instrument. Remove the protective cover just before mounting. Pressure/Vacuum The process fitting must be sealed if there is gauge or low pressure in the vessel. Before use, check if the sealing material is resistant against the measured product and the process temperature.
  • Page 12 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. Fig. 3: Filling and emptying centred OPTISWITCH 3200 C • Contactless electronic switch...
  • Page 13 The vibrating element should protrude into the vessel to avoid buildup. For that reason, avoid using mounting bosses for flanges and screwed fittings. This applies particularly to use with adhesive products. 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.
