2 Introduction
2.2
Intended use
The device is approved for monitoring installations on steel-hulled seagoing ships (e.g. steam and boiler
plant, indirect heating systems) as:
•
Temperature monitor (TW)
•
Safety temperature monitor STW (STB)
•
Safety temperature limiter (STB)
The version complies with DIN EN 14597 and is approved as per the guidelines of the Classification So-
cieties:
•
DNV GL
•
Bureau Veritas
•
Pressure Equipment Directive 2014/68EU (ATH.-SE-20[STW] and ATH.-SE-70[STB] only)
CAUTION!
Failure of the device
Cutting through or kinking the capillary will lead to permanent failure of the device!
NOTE!
If the measuring system breaks, the filling liquid can escape. So far, there is no restrictive health authority
statement on a health hazard in the case of short-term exposure and low concentration, e.g. in the case
of a measuring system breakage.
Note
Physical and toxic features of the expansion means, which could occur in the event of a measuring sys-
tem break.
