説明
The PRE3 is a 3-inch electric contact pressure gauge designed for visual monitoring and automatic control. It features an adjustable magnetic mechanism that prevents accidental contact activation due to vibration. The gauge offers customizable pressure ranges with ±3.0% F.S. accuracy, a 316L stainless-steel wetted system, and a PC window. Equipped with EC1 snap-action contacts (70% silver & 30% nickel, gold-plated), it supports multiple switching functions. Available in bottom mount, back mount, and back flange configurations, the PRE3 is suitable for general industrial use, pump control, fan operation, and pipeline pressure monitoring.
