Our piston sensor models are for liquid applications where durability and long life are required. Their simple design has fewer parts to wear out and also keeps the price low. A magnet attached to the dial pointer shaft follows a spring- loaded sensor magnet that moves as differential pressure changes. In this way the DP displacement of the sensor is translated to our easy-to-read 2.5 to 6-inch diameter dials.
• Heavy duty — to 10,000 psi line pressure • Weatherproof design and rugged construction
