ߜ Mounts Vertically at Top or Bottom of Tank
ߜ Reed Switch Design for High Repeatability
LVN-20, $29, shown actual size.
These liquid level switches are
sealed with potting compound. The
only path for liquid to the electrical
switch would be through the wires.
If the wires are terminated in an
appropriate manner [e.g. NEMA 6
(IP68) connectors], the level switch will meet or exceed a NEMA 6
LVN-10: 1⁄8 NPT LVN-20: 1⁄4 NPT Switch: SPST
Comes complete with operator’s manual.
Ordering Examples: LVN-20, low cost liquid level switch, $35. LVN-10, low cost liquid level switch, $29.
