Dwyer 265ER-S5SS is a Precisor® II Pneumatic and Electro-Pneumatic Positioner suitable for hazardous locations. It has an IP66 enclosure rating and can operate in temperatures ranging from -4 to 158°F (-20 to 70°C). The housing is made from aluminum diecasting or 316SS. It has a screw terminal electrical connection and a 1/2" NPT conduit connection. It has a linearity of ±2% of FS and a repeatability of ±0.5% of FS. The hysteresis is 1% of FS and the sensitivity is ±0.5% of FS. The air consumption is 0.10 SCFM (3 LPM) at 20 psig (1.4 bar) supply and the flow capacity is 28 SCFM (80 LPM) at 20 psig (1.4 bar) supply. The input signal can be either pneumatic (3 to 15 psig or 0.2 to 1 bar) or electro-pneumatic (4-20 mA DC). The air supply required is 20 to 101 psig (1.4 to 7.0 bar) and it has a 1/4" NPT air connection. It has a 0 to 90° stroke.
