Complete condition monitoring and protection module
Gives early warning of fault conditions
Helps avoid plant shut down
Two user set alarm and trip levels
Simply bolts to machine
Users need no special vibration experience or training
Compact and low cost
The MTVS0004 Vibration Switch offers a low cost, simple to install and operate solution to protect all sorts of rotating machinery; motors,
pumps, fans, gearboxes etc. It’s durable case with high IP rating is suitable for long life in harsh industrial environments. Measurements are
made in velocity and compatible with ISO10816 Machine Vibration Severity Test.
Just bolt the unit to a flat surface on your machine, set the appropriate alarm and trip levels, connect the relays to switch alarms or to power
down the machine then connect to the power supply for continuous protection. For restricted access situations or where the vibration must be
monitored on bearing housings external vibration sensors may be used with mounting diameters down to 15mm diameter. Choose either
latching alarm relays requiring operator reset following an over vibration incident or non-latching relays to automatically resume operation as
soon as the fault has cleared.
