Page 2: Installation Precaution
PTU5x - Safety / Mechanical installation The non intrusive system application is now preferred in the level measurements field. For this reason the SGM-LEKTRA developed the PTU50, PTU51 and PTU56 unity to best meet the “GENERAL-PURPOSE” application requests. The PTU50, PTU51 and PTU56 units are compact sensors and have a via connector quick connection. The IP68 protection makes them suitable for external applications with direct exposure to the weather, including areas with diving hazard (up to 1m). -
