Product overview
Cable-connected level probe
A cylindrical metal probe connects through a black boot to the coiled cable.
Metal-neck probe configuration
A raised metal neck joins the cable to the cylindrical probe, with two visible openings near the lower rim.
Filter-base configuration
A wider flat base sits below the metal cylinder, with a visible opening in its side.
PTFE configuration
The white probe housing connects to a coiled white cable. PTFE is an alternative housing material to the metal configurations.
Booted metal probe dimensions
These values describe the cylindrical probe with a black cable boot. Confirm the dimensional units and installation drawing for the selected probe; the metal-neck, filter-base and PTFE versions need their own dimensions.
