Zones categories
Zone 0 (gases and vapours)/20 (dust)
Explosive atmosphere is present continuously, for long periods or frequently.
Zone 1/21
Explosive atmosphere is likely to occur under normal operation, occasionally.
Zone 2/22
Explosive atmosphere is unlikely to occur in normal operation and, if it does, will persist for a short period only.

Using of Instrument
PRE5050M-ATEX – Vibrio Ex unit is certified for using in explosive risk areas zones 1 and 2 with all gases group.

It means:
IIA (acetone, ethanol…), IIB (formaldehyde, ether…) IIC (hydrogen, acetylene, …).

Next conditions must be complies:
1. Accelerometer type must be AC90x or AC91x.
2. Batteries type must be Energizer L91 (1.5V / LiFeS technology).
3. The instrument cannot be used in zone 0.
4. Changing of batteries cannot be done in explosive risk area.
5. The communication cable cannot be done in explosive risk area.
6. The operator must be grounded and the unit must be grounded thru the operator.
