Overspeed Protection

Sensonics Overspeed Protection instrumentation offers a high integrity monitoring system for the safe shutdown of critical rotating plant in the event of an Overspeed situation. Speed Monitoring is an essential activity on most turbines and steam driven pumps where a failure in the control system can result in costly rotor and bearing damage. This in conjunction with lengthy downtimes associated with such repairs drives the requirement for high integrity Overspeed Protection systems.

In addition to providing shutdown through Speed Monitoring an important parameter of the system is the spurious trip performance. The 2 out of 3 voted configuration utilised in the Sensonics Overspeed Protection system virtually eliminates the spurious trip scenario in conjunction with a SIL-3 rating to IEC 61508.
