A New Wireless Temperature Monitoring System from KMSS
01 Jan 2002
Kongsberg Maritime Ship Systems has developed a new diesel engine temperature monitoring system which operates without wiring inside the engine and without the need for slip rings.
The KMSS Sentry system measures the temperature in crank pins, crosshead bearings and other rotating parts. The Sentry, approved by DNV and other classification societies, can be integrated into any existing alarm and monitoring system.
The faster response achieved by Sentry reduces the risk of engine breakdown or damage.
According to DNV, damage of this type represents 14% of all breakdowns in medium speed engines and up to 17% in high speed engines.
Sentry offers patent pending technology with its temperature sensitive Surface Acoustic Wave (SAW) sensor. When in operation this sensor is interrogated by a short pulse radio wave emitted from a stationary antenna inside the engine. These radio signals are processed, and the temperature calculated, in a specific signal processing unit (SPU) which can be mounted directly on the engine. Up to 16 separate sensors can be connected to each SPU.
