Electro static discharge (E.S.D.)
BM 102 non-Ex and Ex gauge electronics are shielded up to 4kV against E.S.D..
Note:
E.S.D. cannot be solved by BM102 E.S.D. protection. It is the customer’s
responsibility to avoid E.S.D. by grounding the tank, product and probe installation.
1
Danger of injury
The probe may receive an electrostatic
discharge during operation; earth the probe
by pushing it against tank wall with a
suitably isolated tool just before touching it
to avoid receiving a shock.
2
Earth the entry pipe and product.
Product deposits on the nozzle and probe
Product build-up can occur under the nozzle: this may weaken the pulse. Avoid cavities that permit
the build-up of deposits.
Tank roof deformation
Tank roofs should support loads of at least 3.5 tonnes or 7700lb for gauge installations using
Ø8mm or 0.3” (type 6) single cable probes.
