1 Introduction
1.2 Application
Depending on the version, the explosion-protected surface-mounting ther-
mostat, type ATH-Ex, can be used as
■ TW temperature monitor
■ STW fail-safe temperature monitor
in areas with an explosion hazard caused by gases, vapors or mists, Zone 1,
or in areas with combustible dust or dust/air mixtures, Zone 21.
1.3 Marking
II 2G Ex ed IIC T6 for potentially explosive gas atmospheres
II 2D Ex tD A21 IP65 T80°C for potentially explosive dust atmospheres
Test certificate: PTB 03 ATEX 1167
CE marking and No. of notified body: CE 0044 .
1.4 Safety notes
Physical and toxicological properties of the substances that may escape in the
event of a system fracture:
– = no; X = yes
If this surface-mounting thermostat is used inside the hazardous area, the
relevant regulations for mounting and operating equipment in such an area
must be observed.
Cutting through or kinking the capillary of surface-mounting thermostat,
type ATH-Ex, will result in permanent instrument failure!
Filling liquid may escape in the event of a measuring system fracture. At pres-
ent there is no restrictive statement from the health authorities concerning any
danger to health over short periods and at low concentrations, e.g. after a
fracture of the measuring system.
