Application & Safety Standards

The 9150072-005 (PWB MB) is a cornerstone of "Ex ia" intrinsically safe installations. Its primary application is within tank gauging systems on oil tankers, bulk carriers, and refinery tank farms. The board acts as a barrier and interface, ensuring that electronic signals within the hazardous "Zone 0" or "Zone 1" areas do not carry sufficient energy to ignite explosive atmospheres. By utilizing the 9150072-005 (9150072-005), operators can aggregate multiple temperature sensor inputs and radar level data into a single, reliable digital output for the control room.
