513 Series

(left to right)


LOW-Range Models (0.5 - 25 psid), HIGH-Range Models (2000 - 1000 psid),
MIDDLE-Range Models (50 - 750 psid)

Series 513 Pressure Transducers are bi-directional wet-wet (BDWW) sensors designed for a wide range of differential measurements where both pressure sources can involve wet or corrosive fluids, each port having a welded, stainless-steel diaphragm.  Typical applications include flow measurement, depth sensing, pressure equalization, and liquid level.

Series 513 models are constructed of stainless-steel, and come in three sizes, depending on nominal range (see the table below).  All units feature mechanical stops to prevent damage when infrequently overloaded.  The diaphragm will hit the stops at about 50% above full-scale range, thus minimizing the possibility of damage from depressurization of one input line.  Low- and middle-range units include viton O-ring seals (metal seals optional).  All high-range units have metal seals.

General Specifications are given below.
