Description

The MTG-E is an expansion thermometer with built-in alarm contacts, featuring a magnetic snap-action switch that provides reliable signal output when the temperature reaches a preset value. Designed for fast response and high-temperature measurement up to 700 °C, it is ideal for process monitoring and automated control applications. With flexible mounting options including bottom mount, back mount, and adjustable angle, as well as selectable single or double contacts (N.O./N.C.), the MTG-E is widely used in machine building, industrial plants, and vessel systems where temperature monitoring and safety interlocking are required.
