Dwyer Instruments’ Series MS MagnesenseTM Differential Pressure Transmitter provides a 4-20 mA or optional 0-10 V process output over selectable ranges of 0.1-, 0.25-, and 0.5-inch w.c., which can be converted to metric ranges of Pascal; plus ±1 or ±2 percent accuracy, depending upon the range along with a field selectable air velocity mode that tracks a fan’s flow curve by using a pitot tube or flow sensing device.
