7330 Pro-Stik II
The BW Controls 7330 Series Magnetostrictive
Level System is an integral assembly that measures
linear motion or liquid level using magnetostrictive
technology. A single level output is provided with field
configurable 4mA and 20mA points in an intrinsically
safe, standard two wire loop-powered configuration.
Magnetostrictive technology is extremely accurate and
requires no calibration during installation. The sensor
works equally well on all clean liquids with a viscosity
of 1500 centipoises or less. Various types of Floats
are available for different applications.
Unlike conventional level instruments, the electronics
are incorporated into the measuring probe and
there is no external electronic housing. This design
utilizes sophisticated Surface Mount Technology
(SMT) integrated into a 5/8” diameter tube, reducing
user’s cost and offers greater options for insertion
and mounting. The self-contained unit provides IP68
protection in a 316 stainless steel enclosure.
The 7330 Pro-Stik II offers unique diagnostic
capabilities. The normal 4 to 20mA output indicates
the position of the float within the span. If the level is
outside of the set span, the output is either 3.9mA or
20.1mA. If the float moves into the Null or Dead Zones
or there is a sensing failure, then the output is 3.8mA
Unpacking
Carefully remove the contents of the shipping carton
and check each item against the packing list before
destroying the packing materials. Any damage must be
reported to the shipping company. If you do not recieve
all of the parts on the packing slip, contact Ametek
at 800-635-0289 (US and Canada) or 248-435-0700
(International).
Most rigid probes are shipped in a Tube. To remove
the metal end cap, use a large, flat blade screw driver
or a metal rod and tap on the inner edge of the cap
until it pivots. Grab the cap and pull it out. Use caution
as the edge of the metal cap may be sharp.
If you have an RMA warranty claim, pack the probe in
a shipping tube or with stiff reinforcement to prevent
the probe from being bent in transit.
Mounting Conditions
1. The 7330 Pro-Stik II Series level system is designed
for industrial applications, but should be mounted
in a location as free as possible from vibration,
corrosive atmospheres, or any possibility of
mechanical damage.
2. Mount the probe in a reasonably accessible location,
away from agitation.
3. Ambient measurement temperature should be
between -40°F and 158°F (-40°C to 70°C).
4. Mount the probe perpendicular with gravity so the
float moves freely along the probe.
CAUTION
When installing probes, do not bend rigid
probes. Permanent damage may result.
Rigid probes, longer than 10 ft., need to
be supported at both ends while handling.
Remove the Caution Tag before installing.
Probes are built with the electronic circuits
sealed inside the tube at the factory. Do not
attempt to open probe or weld on the tube.
5. The Float Retention Clip should be in place at base
of probe after the float is on the tube and the float is
moving smoothly up and down the probe.
