  • Page 7: Mounting Recommendation

    In the case of vertical mounting it is recommended to keep the mentioned distances applied to the length of the electrode (the longer one). All vertically mounted sensors E – Electrode length in mm Fig. 1: Vertical mounting © Dinel, s.r.o. DLS–27...
  • Page 8 The wrong example is in the middle fi gure. Left fi gure – appropriate mounting on the auxiliary vertical plate. In some cases is allowed the variant shown on the right fi gure – but only for DLS–27_–10 type, and only for not blocking materials. For DLS–27_–10 and DLS–27_–20 DLS–27 © Dinel, s.r.o.

    (dependent on adjusted sensitivity). The less is the sensitivity the better is resistance to an adhered rests of media. Sensor is mountable directly into wall of a vessel in horizontal or vertical position by means of welding fl ange. © Dinel, s.r.o. DLS–27...

    (usually inductance and capacity) of the outside intrinsically safe circuit of supply units (NSSU, NDSU, NLCU). If using a dismountable connector socket, the outside diameter of the cable is a maximum of 6 mm. DLS–27 © Dinel, s.r.o.

  • Page 13: Sensor Setting

    If the sensed medium is at your disposal before setting into service it is useful to provide individual setting as follows. In this way it is possible to achieve resistance against sediments. © Dinel, s.r.o. DLS–27...

  • Page 14: Status Signalization

    For minimum level sensing we recommend sensor with normally open output – NO, PO, RO. It is for failure safety reasons – eventual failure of sensor behaves similarly as an exceeding of the limit state. Analogically for maximum level sensing we recommend normally closed outputs – NC, PC, RC. DLS–27 © Dinel, s.r.o.
