The Only One In Its Class
Built-In Lightning Protection
Lightning strikes are always a threat
to exposed electrical infrastructure especially when it’s 40 feet underground.
That’s why we’ve included built-in
lightning protection as a standard
feature for every model (including
intrinsically safe version).
So forget about buying a $300 industrial
surge protector. It’s included.
Class 1, Divizion 1/Zone 0
The PT-500 is built to handle tough
applications - including hazardous
locations. It’s intinsically safe design means
it’s suitable for even the most explosive
environments.
Field Adjustable Zero
Even the best submersible pressure
transducers drift a little over time. Ours
stands apart from the others because
you can adjust the zero point in the eld -
bringing it back within spec.
All it takes is a simple magnet (included).
It’s easy to do and means you won’t need
to have it recalibrated as often.
Re-Usable Cage
Need to protect your sensor? The cage is
the ideal solution. But it costs extra no
matter who you buy from. Ours can be
removed and reused when it’s nally time
to replace your sensor - saving you money.
Tight budgets can be challenging. Why not
save as much of it as you can.
Low Power Consumption
The Modbus and voltage output versions
use very little power and have a very fast response
time - ideal for battery-powered installations.

Impressively Thoughtful Design
At the end of the day, the PT-500 submersible pressure transducer is modeled after your needs.
An accurate, robust sensor was the priority, then we simply thought of you and took it a few
steps further!

your application and get a quote.
Tank Cloud Compatible
As stated, the PT-500’s low power consumption make
it ideal for remote monitoring applications - especially
when you’re relying on solar or battery power. The
Modbus version is compatible with our online remote
monitoring software, Tank Cloud.
View level readings online for free on our Tank Cloud
portal - levelandow.com. You can even add in low cost
data logging and alarms. Tank Cloud means you can
keep an eye on your remote tanks and wells from your
oce or your smartphone.
Contact us today to discuss how remote monitoring
with Tank Cloud can help you save time and money!

Applications
The versatility and reliability of the PT-500 makes it a great multi-purpose level sensor. It excels in water and
hydrocarbon-based liquids where the density of the liquid is consistent. Here are typical applications where you’ll
nd our PT-500 submersible pressure transducer:
• Lift Stations
• Retainer Ponds
• Well Level Monitoring
• Process Tanks
• Remote Level Monitoring
• Chemical Tanks
• Water Storage
• Oil Storage
Featured Conguration: PT-500 + MND Modbus Display
Our Modbus version expands the compatibility of PT-500.
Specically, it also makes it compatible with our Tank Cloud
remote monitoring solution, and our various other Modbus
products - including our MND display.
The MND is a powerful display that can be programmed as a
master, a slave, or a snooper.
When combined in master mode with the PT-500 submersible
pressure transmitter, the MND makes an accurate and easy-touse “digital stick” level measurement tool. This setup is great
for both a stationary installation or a mobile instrument.
This is made possible, largely,
by the ability the MND has to
power another sensor with its
battery. The MND can both
display the PT-500’s reading
and provide it power.
The wiring is also exible. We
can integrate the two by wiring
them together in the factory,
provide you with a connector on the display, or get you a wiring tee.
Contact us to learn more about using the MND and PT-500 together. We can
help you get both congured correctly and ordered together.
Refer to the MND datasheet for more information.
