Economical alternatives to network process transmitters when a digital protocol is not required, Ashcroft’s GC51 and GC52 gauge and differential pressure transmitters have a compact NEMA 4X/IP65 enclosure measuring 2.65 in. in diameter. Stainless steel wetted parts accommodate wet or dry media. A built-in LED display and a 4-20mA output provide local indication and remote signaling. The transmitters measure fluid levels in tanks, water towers and across differential pressures membranes in water purification systems. Ashcroft Inc.; 800-328-8258;
