Metrix Instrument 5550 model Vibralert mechanical/vibration switch, available from Measurement Solutions , is designed to meet all requirements for mechanical switches in a single package. This unit provides economical vibration protection for low to medium speed machinery.
An inertia sensitive mechanism activates a snap-action switch with SPDT output contacts if the vibration exceeds an adjustable set point.
The 5550 model contacts can be used to activate an alarm or initiate equipment shutdown. The housing is weatherproof with an optional hazardous area rating.
Electrical (remote) reset with start-up time delay and a second set of SPDT output contacts to accommodate DPDT needs (e.g. separate trip and trip light circuits) are available.
