Q
I have received a report of several failures of steam turbine governor & stop valve position feedback transducers. The transducers are Balluff make, model BLT-5-E17, installed in a Siemens SGT5-4000F CCGT plant.
The problem seems to be temperature related, with the devices being overheated by heat conducted from the valve bodies.
I was wondering if anyone else out there has similar experience.
