The new GC51 and GC52 gauge and differential pressure transmitters (photo) offer an economical alternative to network process transmitters when a digital protocol is not required. The innovative design features an ultra-compact NEMA 4X/IP65 enclosure measuring only 2.65-in. dia. Stainless-steel wetted parts accommodate either wet or dry media. The GC51 is available in ranges up to 0 – 7,500 psig and the GC52 offers D/P ranges up to 400 in. of water. A built-in LED display and a 4 – 20-mA output provide both local indication and remote signaling. These transmitters are ideal for measuring fluid levels in tanks, water towers and across differential pressure membranes in water purification systems, says the manufacturer. In addition, media isolators can be added for sludge or caustic media installations. — Ashcroft Inc., Stratford, Conn.
