Dust-ignition proof: ATEX II 1 D IP6X T133 ... T400, Zone 20, 21, 22
The installation and deinstallation may only be carried out by specialist personnel that have
knowledge of the concept of the corresponding ignition-proof type "Electrical apparatuses with
protection through housing with isolation of the surface temperature for use in areas in which
combustible dust is present in sufficient quantities that it could lead to fire or explosion (dust-
ignition proof)".
The temperature sensors are to be attached, according to their mounting type (thermowell with
flange, with threaded connector, with sliding connector or as welded thermowell), securely,
sealed and firmly with the respective container. Choose the suitable corresponding connection
element to the application purpose. (Screws, seals etc.)
Only connection cables and wires that fulfill the requirements DIN EN 50281-1-2:1998 Pkt. 11
may be used.
For the TSP111 and TSP311 temperature sensors, a suitable on site thermowell is to be
provided for.

Dust-ignition proof and intrinsic safety: ATEX II 1 D IP6X T133...T400 and ATEX II 1 G Ex ia IIC
T6...T1, Zone 0, 1, 2, 20, 21, 22
See points 3.5.1 and 3.5.2.

Hermetically sealed: ATEX II 1/2 G Ex d IIC T6 ... T4, Zone 1
Caution – Damage to parts!
Avoid temperature increases from heat input or heat accumulation, e.g. through sufficient
distance to hot system parts and thermal isolation, and heat dissipation through unobstructed
air circulation.
For the temperature measurements in Zone 0, thermowells must be used which fulfill the
following requirements:
•
Install suitable thermowells for the zone separation. The SensyTemp TSP321 and 331
temperature sensors are shipped with a corresponding thermowell. For the TSP311
temperature sensor, a suitable on site thermowell is to be provided for.
•
Where required, use suitable temperature-, pressure- and corrosion-resistant sealing
elements.
Thermowell model
Stainless steel thermowells (e.g. according to
DIN 17440) or corrosion-resistant nickel alloy
(e.g. according to DIN 17742)
Thermowells from other steels
Use only prototype-certified ABB measuring insets whose diameter matches the corresponding
hole of the connection head (ignition penetration-proof seam).
These may no longer be used if they have surface damage in the area of the ingnition
penetration-proof seam or the connection head base.
•
Use only separate ignition-proof certified cable glands of a suitable ignition-proof type. ABB
ships standard EEx d approved type ELFIT cable glands.
