The Bently Nevada™ 3500/25 Enhanced Keyphasor Module is
a half-height, two-channel module used to provide
Keyphasor signals to the monitor modules in a 3500 rack. The
module receives input signals from proximity probes or
magnetic pickups and converts the signals to digital
Keyphasor signals that indicate when the Keyphasor mark on
the shaft coincides with the Keyphasor transducer. The 3500
Machinery Protection System can accept up to four
Keyphasor signals for normal configuration and up to eight
Keyphasor signals in a paired configuration.
The Enhanced Keyphasor Module is an improved 3500
system module. It offers expanded Keyphasor signal
processing capabilities over the previous design while
maintaining complete downward-compatibility in terms of
form, fit and function with existing Keyphasor modules for use
in legacy systems. The Keyphasor module, PWA 125792-01, is
completely replaced by the updated 149369-01 module.
When a system Keyphasor input is required for Triple Modular
Redundant (TMR) applications, the 3500 system should
employ two Keyphasor modules. In this configuration, the
modules work in parallel to provide both a primary and
secondary Keyphasor signal to the other modules in the rack.
