Selecting conduit for below ground bypasses
When the sensor cable must go below ground to reach the other side of a gate, or go through or
below a building or object, the cable must be protected by using conduit. For sites that include
periods of freezing weather, solid wall conduit is required. For sites in temperate climates that do
not experience freezing weather, split conduit can be used.
