Smart Valve Positioner
ASD-7000 4-20mA Flameproof Smart Positioners
Archer’s ASD Smart Positioners excel in the harsh working conditions found in the toughest environments. Compared with other smart positioners, the is easier to calibrate and program, ASDis more resistant to dirty air and vibration due to its non contact feedback sensor, and has the lowest cost of ownership.
A wide rage of communication options is available including , HARTProfibus and Foundation Fieldbus. It also carries and x ATEX IECEcertification for Intrinsically Safe and Flameproof. For severely corrosive environments a stainless steel enclosure is available.
