Measurement
series sensors and
CHEM
ware put the power of ultrasonics
in your hands. You can quickly
adjust, optimize, save and clone
your applications quickly without
calibration!
These sensors are housed in
a rugged, chemically inert PVDF
sealed housing for long life. They
mount above the material surface
and measure distance downward
without contact. Outputs respond
to that measured distance.
Applications include pump
control, bulk inventory, batch processing, water management and
high/low level alarms.
SenixVIEW soft-
Features
Level Measurements
• Long or short measurements
• Unaffected by optical factors
like color and transparency
• Computer (PC) software allows
remote adjustment
Packaging & Performance
• Durable housing for long life
• Bottom and top thread mounts
• Short & overload protected I/O
• Adjustable filters compensate
for tank mixers or turbulence
• Temperature compensation for
improved accuracy
• Adjustable sensitivity
Free Functionality
Use adjustable interface features
like switch hysteresis and time
delays to build complete solutions such as pump controls to
maintain level. Save cost by eliminating PLCs, delay circuits and
time delay relays!
SenixVIEW PC
Software included!
PC Setup Power!
Use SenixVIEW software (see
separate data sheet) to adjust all
sensor features. You can view,
analyze or log data to optimize
your application. Disconnect and
the sensor retains the setup.
Copy without Calibration
Application setups can be saved
for future recall. From a single
sensor inventory part you can
quickly clone sensors, without
recalibration, for any number of
different field installations.

Multiple Outputs
In addition to the model's serial
data interface there are five
simultaneous outputs, fully configurable with SenixVIEW.
Analog Outputs (3)
These include voltage (0-10 VDC)
and two current loops (4-20 mA
sinking and sourcing). Both output types have user-selectable
voltage/current ranges and endpoints for best resolution. Easily
invert the analog output slope.
Switches (2)
Two switches are SenixVIEW
configurable as "PNP" or "NPN"
type (sourcing or sinking). Each
has adjustable set point, hysteresis, window, initial conditions,
ON delay, OFF delay and loss of
target response to easily create
controls and alarms!
