Vibration Alarm - Explosion Proof

VS1 Relay Output(XP Housing W/Window) 

VS1
The VS1 is a low-level vibration switch optimized to monitor non-intentionally vibrating machinery for the effects of imbalance, misalignment, looseness or wear (e.g. bearings). The trip-point setting range is 0.1→2.2 in/s. The VS1 is designed per ISO 10816-1 Mechanical Vibration - Evaluation of machine Vibration by measurements on non-rotating parts.

VS1 and VS2 monitor the machine surface
to which they are attached and alarm when vibration either exceeds or falls below the trip-point setting, according to the alarm over/under switch setting. Each have three LED indicators providing power, vibration and alarm status. The isolated transistor or relay output may be wired for machine shutdown or as part of an early warning system. The adjustable alarm delay prevents false alarms by allowing the user to set the minimum continuous fault condition time for alarm, thus preventing needless system shutdowns during operation or startup.
Two rugged cast aluminum housing options are available for the VS1 and VS2: the compact NEMA 4X and the Class I and II rated explosion proof (XP). A separate 24 VDC power supply is also available.
