Why Refineries in Middle East and China Love It Most plants still have hundreds of old explosion-proof pneumatic positioners from the 1990s. When they break, replacing with European smart Ex d positioners costs a fortune. The TS800 Ex d version costs almost the same as repairing the old pneumatic one, but you get HART, auto-tune, and diagnostics. Turnaround teams just swap them one-for-one and suddenly the whole unit has digital communication. Explosion-Proof Specials Ex d
