The ProtEX+ Series delivers reliable, high-visibility indication and control for both analog and pulse signals in hazardous industrial environments where safety, durability, and compliance are essential. Fully certified as explosion-proof and intrinsically safe, these meters are approved for use in classified areas and housed in rugged aluminum or stainless steel enclosures designed to perform across wide operating temperature ranges. In addition to 4–20 mA process applications, the ProtEX+ Series uniquely offers pulse input rate and totalizer models, allowing users to monitor flow, counts, or totals directly in hazardous locations using a single instrument. A clear dual-line display with an integrated bargraph makes information easy to interpret at a glance, while a standard backlight with an optional red alarm backlight provides immediate visual indication of alarm conditions. Solid-state relays enable advanced control capabilities such as pump control for level applications and batch control on rate and totalizer models. CapTouch through-glass buttons allow full operation without opening the enclosure, helping maintain safety and uptime in hazardous areas. Designed for demanding environments, the ProtEX+ Series combines advanced functionality, intuitive operation, and rugged construction in a hazardous-area solution built for real-world industrial applications.
