Instrucciones de seguridad
The ST100A Series consist of a sensing element and associated integral or remote mounted electronics
mounted in a type “d” flameproof enclosure.
The relationship between the temperature class, the maximum surface temperature, the ambient
temperature and the process temperature is as follows:
Electronic Enclosure: T6/T85°C for an ambient temperature range of
Electronic Enclosure: T5/T100°C for an ambient temperature range of
Electronic Enclosure: T4/T135°C for an ambient temperature range of
For
ATEX/IECEx Agency Approval system with AST configuration, the relationship between the
temperature class and process temperature range is as follows:
Probe: T4/T135°C for a process temperature range of -40°C to +89°C
Probe: T3/T200°C for a process temperature range of -40°C to +154°C
Probe: T2/T300°C for a process temperature range of -40°C to +254°C
Probe: T1/T450°C for a process temperature range of -40°C to +404°C
For
ATEX/IECEx Agency Approval system with Constant Power configuration, the relationship between the
temperature class and process temperature range is as follows:
Probe: T4/T135°C for a process temperature range of -40°C to +57°C
Probe: T3/T200°C for a process temperature range of -40°C to +122°C
Probe: T2/T300°C for a process temperature range of -40°C to +222°C
Probe: T1/T450°C for a process temperature range of -40°C to +372°C
