MTVS0004 Industrial Vibration Switch

The MTVS0004 is a stand-alone vibration switch that integrates an accelerometer sensor and control electronics into a housing. It triggers an internal relay when vibration exceeds a user-defined threshold.

Output: SPDT (Single Pole Double Throw) relay. The alarm level and time delay are independently adjustable internally. The delay prevents tripping due to transient vibration spikes during the start-up of heavy motors or sudden load variations. Reset: manual or remote.

Die-cast aluminum housing with IP67 protection rating. Operating temperature: -20 °C to +80 °C. Power supply: 24 V DC (AC options available). Mounting: surface mounting.

Applications: industrial fans, cooling towers, centrifugal pumps, and gearboxes. No additional analytical instrumentation is required.

Technical FAQs

1. How do I adjust the alarm trigger level?
In situ, using an internal potentiometer accessible by removing the cover.

2. What is the purpose of the configurable time delay?
The relay only switches when the vibration exceeds the alarm limit for a sustained period of time. This filters out isolated events and prevents unnecessary downtime.

3. Does it require additional instrumentation to operate?
No. It is an all-in-one (stand-alone) device. It only requires a 24V power supply and wiring from the relay to the engine stop circuit or alarm system.
