All DVC6200 series instruments utilize a patented linkage-less, non-contact feedback design to detect valve position. This valve positioning technology eliminates any travel feedback issues caused by corrosion, high cycle or high vibration applications.
In addition to external protection, corrosion resistance is found within the stainless steel housing with the digital controller's fully encapsulated printed wiring boards. Internal component protection is further enhanced by a separate, weather-tight field wiring terminal box that isolates the field wiring connection from other areas of the instrument.
