The APG PT-500 is a rugged submersible pressure transmitter designed for tank liquid level measurement, water and wastewater applications, and well depth measurement. The versatility and reliability of the PT-500 makes it a great multi-purpose level sensor. It exceeds at water and hydrocarbon based liquids where the density of the liquid is consistent.

The PT-500 has a range of up to 300 psi (or 450 ftH2O) with an accuracy of ≤ 0.50% of span (BFSL). The zero point can be easily reset in the field so if the unit drifts a bit it can be quickly brought back within spec meaning you won't need to have the transducer recalibrated as often. Each transducer also includes built-in lightning protection as a standard feature protecting the units and saving users from needing an expensive industrial surge protector.

The PT-500 is built to handle tough applications - including hazardous locations. It's intrinsically safe design, which is certified CSA Class 1, Division 1/Zone 0, means it's suitable for even the most explosive environments. For especially tough environments cages are available to protect the transducer

The PT-500 has low power consumption making it ideal for remote monitoring applications, especially those which rely on solar or battery power. The Modbus version is compatible with APG's online remote monitoring software, Tank Cloud. Level readings can be viewed online for free on the Tank Cloud portal. Low cost data logging and alarms can even be added. Tank Cloud means you can keep an eye on your remote tanks and wells from your office or your smartphone.
