I got this from google's news:
New Ultra-Compact Pressure Transmitters"The new Ashcroft® GC51 and GC52 gauge and differential pressure transmitters offer the perfect 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 diameter. Stainless steel wetted parts accommodate either wet or dry media. The GC51 is available in ranges up to 0-7500 psig and the GC52 offers D/P ranges up to 400 inches of water. A built-in LED display and a 4-20mA output provide both local indication and remote signaling. Ashcroft® GC series transmitters are ideal for measuring fluid levels in tanks, water towers and across differential pressures membranes in water purification systems. In addition, Ashcroft® media isolators can be added for sludge or caustic media installations."
