The L150 Level Swichgage® instrument is a combination liquid level gauge and low limit switch;
the instrument includes (1) a chamber with pivotal float, (2) an indicating dial with pointer, and
(3) a low level contact. When properly installed and maintained, the float operates the pointer
which, in turn, both indicates level during normal operation, and closes a switching circuit if the
level falls to the low-limit set point.
The L150 features a field adjustable set point. The unit can be mounted away from the engine
for protection from vibration and extreme heat. The set point can be adjusted at any time.
The primary use of the L150 is for engine cooling systems, surge or expansion tanks, condenser
radiator or vapor phase systems, pressurized or atmospheric systems. The L150 Liquid Level
Swichgage® instrument can also be used to monitor lube oil, hydraulic fluid or diesel fuel reservoirs
and activate alarms and/or shut-down at a predetermined minimum level. This instrument is built
for low pressure systems with a maximum of 25 psi (172 kPa) [1.72 bar].
Contact Rating: 2 A @ 30 VAC/DC.
Die cast aluminum, poly-urethane coated case; brass float; polycarbonate lens.
