Protection Systems

Monitoring and Protection Systems for Rotating Equipment with increased (SIL2) and highest safety requirements (SIL3)

Customized to the specific requirements of each customer BRAUN offers a comprehensive range of protection systems – from the single channel solution to satisfy advanced safety

considerations and up to high availability 2oo3 solutions which utilize triple-modular-redundancy (TMR) to achieve the highest level of system safety and machine availability.

Single Channel Protection Systems up to SIL2

Rotational speed monitoring for extended safety requirements
for monitoring of motors, pumps and small turbines

Single Channel solutions in 1oo1, 1oo2 or 2oo2 architecture

  • Single measuring channel devices with sensor monitoring and self-test (1oo1)
  • Two devices configured so that their respective output contacts are linked to a system incorporating redundancy (1oo2 or 2oo2)
  • SIL2 / IEC 61508:2010 compliant

Triple Channel Protection Systems (TMR) up to SIL3

Monitoring and Protection Systems for highest safety requirements
for protection against overspeed and other critical conditions for rotating equipment and turbomachinery such as turbines, compressors, and expanders by monitoring of additional trip criteria such as emergency stop, over pressure and over temperature.

Triple Channel Protection Systems TMR (triple-modular-redundant), solutions in 2oo3 architecture
