AMETEK 7330 Pro-Stik II User Manual
7330X Pro-Stik II Sensor Data Sheet
Stainless Steel Magnetostrictive Sensor
with Field Programmable Span
The 7330X Pro-Stik II takes fi eld proven
magnetostrictive sensing technology and
incorporates features such as intrinsic
safety and a fi eld programmable span.
This is packaged in our patented Stik
design, making the Pro-Stik II ideal for
level monitoring in a variety of liquids and
tanks. Sensors are available in rigid 316
stainless steel up to 24 feet.
The stainless steel version is available
with a mini connector or 3/4” NPT fi tting
that can be joined to an optional housing
with terminal connectors and zero/span
push-but tons. The stainless steel version
offers a totally welded construction and
may be provided with cathodic protec tion.
The sensor’s electronics are SMT
components in a 5/8” diameter sensing
tube. This packaging breakthrough
eliminates the electron ics enclosure
at the top of the sensor, improving the
environmental seal and offering greater
options for insertion and mounting in tanks
and vessels.
The 7330X Pro-Stik II is a loop powered
intrinsically safe sensor with a scaleable
4 - 20mA span that provides 0.1%
accuracy, full scale. The only calibration
required is to set the upper and lower
limits of the span.
The probe provides a security feature by
utilizing a timing sequence that is used
to unlock the probe for programming.
This ensures that the span cannot be
accidentally programmed by someone in
the fi eld.
The unique diagnostic output pro vides
continuous information about the fl oat’s
position and passcode protection for
programming.
The sensor can be “Bench” calibrated
to set the zero and span or an optional
housing with push-button setting of the
zero and span at the tank is available.
If The fl oat is... Output
Below set span, but within active region 3.9mA
Above set span, but within active region 20.1mA
Either above or below active range or
signal is lost
3.8mA
A variety of fl oats and mounting
accessories are avail able to fi t virtually any
application. In addition, a fl exible (PVDF)
probe is available for lengths up to 40
feet, and a 3A sanitary probe is available
for food processing and pharamecutical
applications. Contact the factory to match
your needs today.
