The Series 608 is an FM approved, intrinsically-safe transmitter that provides accurate monitoring of very low differential pressures. The ultra-thin silicone diaphragm can detect down to one micron of deflection, while withstanding up to 100 psig of static pressure. Unit features a standard 2-wire, 4 to 20 mA output and a NEMA 4X stainless steel housing. Full-scale accuracies of 0.25% and 0.5% are available on ranges as low as 0 to 0.1 inches w.c. up to 0 to 25 inches w.c. including compound ranges.
