A.4 Process Pressure/Temperature Derating Curves 

SITRANS LR250 (PROFIBUS PA) 
Operating Instructions, 08/2014, A5E32221386-AC

A.4

 

Process Pressure/Temperature Derating Curves 

 

 

WARNING 

Exceeded maximum permissible operating pressure 
Danger of injury or poisoning. 
The maximum permissible operating pressure depends on the device version. The device 

can be damaged if the operating pressure is exceeded. Hot, toxic and corrosive process 

media could be released. 

•

 

Make sure that the device is suitable for the maximum permissible operating pressure of 

your system. 

 

 

DANGER 

Pressure applications 
Danger to personnel, system and environment will result from improper disassembly. 

•

 

Never attempt to loosen, remove, or disassemble process connection while vessel 

contents are under pressure. 

 

 

WARNING 

Pressure applications 
Danger to personnel, system and environment can result from improper installation. 

•

 

Improper installation may result in loss of process pressure. 

 

 

WARNING 

Unsuitable connecting parts 
Danger of injury or poisoning.  
In case of improper mounting hot, toxic and corrosive process media could be released at 

the connections. 

•

 

Ensure that connecting parts (such as flange gaskets and bolts) are suitable for 

connection and process media. 

 

 

 

Note 
Material compatibility 
Siemens can provide you with support concerning selection of sensor components wetted by 

process media. However, you are responsible for the selection of components. Siemens 

accepts no liability for faults or failures resulting from incompatible materials.
