Feature Comparisons of LF, LTA-2 and LTR Models:
even probe buildup. So unlike the
competition, the LF won’t shut down
your boiler on a false low water
condition due to a dirty probe, or shut
down every 10 minutes to check for
proper water level. You can now run
your steam boiler flat out for a significant
gain in efficiency and operational safety.
By processing and comparing two
separate signals coming back through
the standard probe, the DualVision
®
technology automatically determines the
required delay on make (DOM) and
delay on break (DOB) settings for any
style steam boiler under any system con-
ditions. The LF's patented smarts means
no more dip switches to set or dials to
program. External LEDs and a test but-
ton verify that everything is installed and
wired correctly before you leave the job.
You can even wire in an alarm or electric
water feeder.
The LF Series is available in 24 or 120
VAC models, automatic or manual reset
models, ½” and ¾” NPT process con-
nection sizes and a number of probe
lengths to match your job requirements.
