Emer­son Process Man­age­ment has in­tro­duced the Fisher Field­vue DVC6200p se­ries of dig­i­tal valve con­trollers.

The DVC6200p se­ries is an ideal so­lu­tion for ap­pli­ca­tions in which ac­ces­si­bil­ity, ex­treme tem­per­a­tures (up to 120°C/250°F), ex­treme vi­bra­tion or con­fined space make in­te­gral mount­ing dif­fi­cult or im­prac­ti­cal.

In­dus­tries such as pulp and pa­per, and metal and min­ing have typ­i­cally pre­ferred to iso­late valve­mounted in­stru­ments from harsh en­vi­ron­ments. With the re­mote mount ver­sion of DVC6200p, only the valve po­si­tion feed­back is mounted on the con­trol valve, while the re­main­der of the dig­i­tal valve con­troller can be mounted more than 90m away in a less se­vere or more ac­ces­si­ble en­vi­ron­ment.

The re­mote valve mounted feed­back unit uses the patented Field­vue link­age­less, non-con­tact feed­back tech­nol­ogy in which phys­i­cal con­tact has been elim­i­nated be­tween the valve stem and the in­stru­ment. With no link­age to wear, loosen, cor­rode or vi­brate, the feed­back unit can with­stand a plant’s op­er­at­ing ex­tremes.

With over one and half mil­lion units in­stalled world­wide, Field­vue dig­i­tal valve con­trollers prove highly suited to dif­fi­cult process en­vi­ron­ments where they pro­vide un­matched valve op­er­a­tion.

Us­ing the best of Profibus PA, the DVC6200p se­ries pro­vides a wealth of alerts, trends, and di­ag­nos­tics to al­low for vis­i­bil­ity and con­trol,

The DVC6200p sup­ports en­hanced de­vice de­scrip­tion (EDD) files that al­low for quick and easy con­fig­u­ra­tion.

The Field­vue DVC6200p dig­i­tal valve con­troller is cer­ti­fied to Pro­file 3.02 for Profibus PA de­vices by the PROFIBUS Nutze­ror­gan­i­sa­tion a.V (PNO).

The DVC6200p is of­fered with CSA, IECEx, ATEX and FM hazardous area ap­provals as well as other cer­ti­fi­ca­tions/ ap­provals. It is also listed in the Lloyd’s Reg­is­ter for in­dus­trial, marine and off­shore use.
