Vibration Monitor for Explosive Atmospheres
Model - 1500EX

1. Can be used in a hazardous area where explosive gases or the like are in existence.

2. Vibration modes for acceleration, velocity and displacement can be select with internal switch.

3. The housing is of pressure and explosion-proof construction.

4. The sensor is combined with the amplifier via a flexible wire conduit.

5. Alarm level setting at a step of 1% from 1 to 99% with internal digital switch.

6. Two different alarming steps, one for self-holding operation and the other for automatic resetting operation are provided.

7. Alarm delay of up to 60 seconds can be set to prevent an incorrect action.

8. Usable for monitoring vibrations in motors, fans, piping, large-sized cranes, etc.
