4-20mA Pressure Transmitters: Understanding Industrial Standard Current Loop Communication
Walk into virtually any industrial facility worldwide—from Texas oil refineries to German chemical plants, Australian mining operations to Japanese automotive factories—and you’ll find thousands of 4-20mA pressure transmitters reliably communicating measurement data across distances exceeding 1,000 meters through simple two-wire connections, immune to electrical noise that would render voltage signals useless. Yet despite ubiquity spanning […]
