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.

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.
