The
Thermo Ramsey Model 60-23P and 60-23PX Under Speed Switches
provide a low cost, dependable, versatile and simple means of
Rotational Velocity Monitoring of a shaft or other rotating
equipment. The Model 60-23P features one-piece unitized construction.
The electronics and output contacts are housed in the same unit
with the detector. Only two (2) bolts are required to mount
the unit. The non-contacting proximity-type detector has no
moving parts. Once the simple installation is completed, the
device is virtually maintenance-free. Two 10-second time delays
add important benefits to the package. The first delay prevents
nuisance alarms to start-up. The second delay is from an alarm
to normal condition after the under speed status has been corrected.
