The Model 366 vibration switch is a vibration
sensitive device that protects rotating and reciprocating machinery from
extensive damage resulting from mechanical malfunction. When the vibration
level of a vibration switch protected machine exceeds normal by a pre-selected
amount, an internal switch closes, actuating either an audible warning
system or a shutdown circuit before costly damage occurs. Failing
bearings, broken blades and similar malfunctions cause increased imbalance
or high frequency vibration detectable with the vibration switch. It is designed for maintenance-free service in permanent
installations where general purpose weather-resistant enclosures are
required.
The Model 366 vibration switch is an acceleration sensitive instrument
that measures the total acceleratory shock present on the machine.
Acceleration is a vibration characteristic of prime importance in cases of
mechanical failure on reciprocating or rotating machinery. Acceleration is
directly related to the shock forces (impact) acting on a machine - thus
the vibration switch offers a valid measurement of the destructive forces
acting on the machine.
Accelerator measurements made by the Model 366 are the
summation of all of the individual accelerations giving a total
destructive force acting on the machine - the result is positive
protection.
Features & Benefits
•
Acceleration sensitive- Measures total destructive shock, not
displacement.
• No
maintenance- No moving parts except when set-point is exceeded.
• Continuous
protection- No attention required after installation.
• Long life-
Instrument is rugged and durable - no wearing parts.
• Reset-
Choice of remote electrical or manual at unit.
• Self
powered- Does not require any form of external power to operate.
