  • Page 7: Product Description

    Housing cover Housing with electronics Process fitting Principle of operation OPTISWITCH 3300 C is a point level sensor with tuning fork for point Application area level detection. It is designed for industrial use in all areas of process technology and is preferably used for bulk solids.

  • Page 8: Operation

    3 Product description Solid detection in water If OPTISWITCH 3300 C was ordered for solids detection in water, the tuning fork is set to the density of water. In air or when immersed in water (density: 1 g/cm³/0.036 lbs/in), OPTISWITCH 3300 C signals "uncovered". Only when the vibrating element is also covered with solids (e.g. sand, sludge, gravel etc.) will the sensor signal "covered". Function monitoring The electronics module of OPTISWITCH 3300 C monitors continu- ously the following criteria: •...

  • Page 10: Mounting

    You can find the specifications in chapter "Technical data" and on the nameplate. In general, OPTISWITCH 3300 C can be installed in any position. The Switching point instrument only has to be mounted in such a way that the vibrating element is at the height of the desired switching point.

  • Page 11: Mounting Instructions

    For this reason, do not use an overly long extension tube for OPTISWITCH 3300 C, but check if you can mount a short level switch on the side of the vessel in horizontal position.
  • Page 12 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.

    • Signal lamp (5) Note: As a rule, always set the mode with mode switch (2) before starting the setup of OPTISWITCH 3300 C . If the instrument is used in con- junction with a signal conditioning instrument, always set the mode switch (2) on OPTISWITCH 3300 C to max. mode. The mode is selected on the signal conditioning instrument with the mode switch.

    6 Setup With the potentiometer you can adapt the switching point to the solid. Switching point adapta- tion (1) It is already preset and must only be modified in special cases. By default, the potentiometer of OPTISWITCH 3300 C is set to the right stop (> 0.02 g/cm³ or 0.0008 lbs/in³). In case of very light-weight solids, turn the potentiometer to the left stop (> 0.008 g/cm³ or 0.0003 lbs/in³). OPTISWITCH 3300 C will thus be more sensitive and can detect light-weight solids more reliably.
