When it comes to gas detection in industrial environments, accuracy, reliability, and durability are non-negotiable. That’s where the 2-Wire Explosion Proof Transmitter steps in—a purpose-built solution designed for hazardous and high-demand settings such as refineries, wastewater facilities, and chemical plants. Equipped with the latest in gas detection technology, this transmitter is built to perform—no matter how harsh the environment.
Built to Endure, Engineered to Perform
This explosion-proof transmitter is housed in a rugged aluminum enclosure with a 303 stainless-steel sensor housing, offering exceptional protection against impact, corrosion, and the elements. Its electrochemical sensor operates on a loop-powered 2-wire system with a reliable 4–20 mA analog output, making it ideal for a wide variety of industrial applications.
A 3-character, 7-segment display with a backlit screen ensures visibility in low-light and bright outdoor conditions. With three push-button controls (MENU, ADD, SUB) and magnetic non-intrusive switches, users can calibrate or configure the transmitter without ever opening the enclosure—an essential feature for use in hazardous or explosive atmospheres.
