Steam turbine speed measuring system
Steam turbine speed measuring system
(OP)
Hi all,
Can someone clearly explain how speed gear teeth number is considered when to install speed measuring system on a steam turbine. What means "frequency resolution" when to talk about sensor specifications? And what is the relationship that should exist between the speed sensor and a possible 4..20mA frequency/current converter in terms of frequency related parameters (resolution frequency, range, etc, gear teeth number, etc.)?
Thanks a lot.
