3. The LLS100 level switch should be located if possible for easy access for service Sensor enclosure should not be exposed to ambient temperatures below 40 C 40 F or above 85 C 185 F It is preferable the switch is not installed in proximity to high voltage wires or other sources of high electrical noise 2 1 Conductive Probes For conductive liquids LLS100 uses bare stainless steel probe Standard length of the probe is 1 2 5cm The probe length can be customer specified for the level of liquid desired to be measured 2 2 LLS100 Installation General Standard probe entry into a tank is via 1 4 NPT opening but other fitting sizes are available When mounting the level switch it should be noted that the rod does not touch the vessel wall TO SCREW IN SWITCH THREADED ENTRY USE WRENCH ON HEX ONLY Do not use a pipe wrench on the body of the level switch Mounting in Metallic Vessel The reference ground for this installation is typically the metal wall of the vessel especially for top mounted probes Use conductive sealant such as copper on NPT threads if possible When using Teflon sealant make sure there is a GOOD ELECTRICAL CONNECTION BETWEEN THE VESSEL AND THE FITTING of the switch Use ground or conductivity tester ohm meter For horizontally or bottom mounted probes the reference ground is not as important since the change in switch output can be achieved by liquid being in contact with the probe and the switch fitt
