Four models are available, which are grouped into two basic versions: low-volume output units (non-relay) and high-volume output units (relay). Features•hypodermic needle test point allows easy output pressure signal measurement•barbed air connections for 5/32 or 1/4 in. O.D. polytubing•compact, simple design for ease of installation on a wide range of mounting surfaces, including direct mounting on pneumatic valve actuators•factory set, fully adjustable zero and span facilitates field calibrationSelection ChartAccessoriesSpecificationsCode NumberOutputInputInput RangeFactory Output Range psig (kPa)EP-8000-111.Low-volume models are one-pipe instruments requiring a 0.007 in.
