The 7100 Stik Liquid Level Sensor takes eld proven
magnetostrictive sensing technology and packages it
in a revolutionary new way for greater reliability and
for easy installation and mounting. It is ideal for liquid
level monitoring of product level, interface level and leak
detection in a wide variety of liquid media in both above
ground and below ground storage tanks.

Proven Magnetostrictive Sensing Performance in a Revolutionary New Package
All The Electronics Are Down The Tube
7100 Leak Detect Stik™ Data Sheet
All sensor electronics are SMT components integrated
into the 5/8” diameter sensing tube. Sensors are available
in stainless steel or exible PVDF housings. The stainless
steel version has either a mini connector or a right angle
conduit tting. The exible PVDF version is available with
a threaded tting and a 2’ cable (see dimensional drawing
on reverse side for connector details).
This breakthrough in package design eliminates the bulky
electronics enclosure at the top of the sensor and offers
you greater options for insertion and mounting in tanks
and vessels. In addition, standard oat packages are
available which allow sensor insertion into tank openings
as small as two inches.
The 316 stainless steel version is a totally welded
construction, and has a cathodic protection boot for use
in a wide variety of applications. The Flex-Stik™ version
employs a exible housing and provides cost effective
level monitoring in deep tanks.
The all SMT electronics have PPM (Pulse Position
Modulated) outputs for product and interface level and for
temperature measurement, which are all superimposed
on the two wire power line. All units are Intrinsically Safe
and approved for use in hazardous locations.
The 7100 Liquid Level Sensor’s inherently lower
cost design provides more options, offers savings
on installation and mounting and has the ultimate in
“designed-in” reliability.
