Dwyer 185EL-S1 | Linear Smart Positioner | HART, single action, aluminium
The Dwyer 185EL-S1 is a Series 185 smart positioner in an aluminium enclosure, configured for single action with HART communication. It positions linear-motion valves such as globe valves from a 4-20 mA input and shows its condition on an external LCD.
- Auto calibration routine and analog feedback signal (185EL-S1)
- 185EL-S1 accuracy: linearity ±0.5% FS, repeatability ±0.3% FS, sensitivity ±0.2% FS
- 185EL-S1 supply air 35-116 psi (2.4-8 bar), flow capacity 2.1 scfm at 20 psig
- Stroke range of the 185EL-S1: 10 to 150 mm or 0 to 90°
- 185EL-S1 aluminium enclosure rated NEMA 4X (IP66); weight 3.3 lb (1.5 kg)
