Proper Mounting - Siemens SITRANS TS100 Compact Operating Instructions

Process load
The thermowell is affected by the static, dynamic and chemical load from the process
parameters, e.g. static and dynamic load, flow induced vortexes. This has influence to the
shape of the thermometer, stem diameter and insertion length.
Ensure that the applicable and relevant directives and standards are respected, e.g. ASME
PTC 19.3, DIN43772 Annex 1-2, AD-directive, VDI/VDE 3511-5.
In critical applications, a thermowell stress calculation according ASME PTC 19.3-TW2016
or Dittrich/Klotter-method is recommended as an engineering service.
4.1.2

Proper mounting

Protective tube ruptures
Protective tubes that are not suitable for the process or application in question can rupture
and result in serious damage to property and personal injuries.
• Make sure that the protective tube is suitable for the respective mounting method and
Electrostatic charge
Danger of explosion in hazardous areas if electrostatic charges develop, for example, in
strong airflows in close proximity to belt conveyors.
• Avoid electrostatic charge at the plastic head type BM0 when defining the installation
Note
Penetration of water into the plastic head type BM0
Device failure.
• To reach IP54 with a plastic head type BM0, make sure that the mounting angle is in the
range of -14 to 194° (208°, see image below).
