Rangeable Pressure Transmitter GC51 Series

Rangeable Pressure Transmitter


The Ashcroft GC51 Rangeable Pressure Transmitter is a compact alternative to the conventional process transmitter available in compound and gauge ranges. The ranges span from Vacuum to 15 PSI, 30 PSI, or 50 PSI compound ranges and 0 to 7500 PSI ranges. The GC51 Series features a two wire 4-20mA output, backlit LCD display, stainless steel wetted parts, and NEMA 4X, IP65, robust aluminum housing. The range and output allows for rescaling and setting of user defined units.
