Model LS7000 Level
Switch |
 |
The
LS7000 has features that make it the most versatile level control
on the market today. It can measure virtually any liquid, dry material
or interface. The proprietary radio
frequency (RF) balanced impedence bridge has exceptional temperature
stability, thus eliminating the need to recalibrate the unit from
season to season.
Every standard unit has an on-board fuse and surge suppressor to
protect the circuitry from power surges. Additionally, a static
suppression circuit protects against hostile bin environments created
by static-prone materials such as plastic pellets. The built-in timer allows the user to select ON DELAY or OFF DELAY
operation if desired. The timing range is adjustable from 1/8 second
to 2 hours. The timer can be used to ignore wave action in a turbulent
vessel, or the timer can be used to pump down a sump with a single
probe.
Calibration
All
the necessary calibration indicators are on-board so all you need
to calibrate the LS7000 is a small screwdriver. The on-board test
switch allows manual testing of the outputs and your alarm/control
devices. When the probe is installed, it is calibrated in absence of material
touching the probe. When the desired material comes in contact with
the probe, the LS7000 is activated and gives the desired output. If the probe you ordered is too long, simply cut it off to the desired
length with a saw. If you need to add length, just weld on additional
rods. Probes of all lengths are available from the factory. Fail-safe electronics provide peace of mind. The modular electronics
make trouble shooting and repair a snap. The entire unit is backed
by our two
year warranty.
Construction
The
probe is made of solid 316 stainless steel rod and the insulator
is made of Teflon. The seals are made with Viton "O" rings.
All the electronics are housed in a cast aluminum explosion-proof
enclosure. Special materials of construction are available.
