Dear Sirs,
We are using bently nevada 3500 system for our turbine supervisory system. Now the problem is the analog output we are taken from Bently Nevada to our DCS (yokogawa) is showing wrong value for a second oftenly. For example, While turbine running we are getting 3000 rpm but for a second the speed output suddenly fluctuate to 2600rpm and resume to earlier point i.e 3000rpm. we have another speed output from the Woodward governor 505E, that's working properly doesn't have any problem.
Please explain what we have to do to clear the problem, because we have critical interlock with this speed like JOP Auto start at 1200 rpm)
for your information i have already checked cable shield that was found ok and i have changed the DCS channel also but still the problem persist.
Please kindly give us a solution.
