Description

The sensor with bi-metal thermal switch is screwed into a small hole in the cooling water hose directly behind the exhaust manifold and warns of a lack of cooling water before the engine heats up too much. The sensor is wired to a free slot on the engine control panel or a separate VETUS alarm indicator (see accessories). At 71 °C, the sensor reacts and closes the circuit; a warning light and acoustic alarm are triggered on the panel or the external control. This allows the crew to switch off the engine before the exhaust gases, which are over 300 degrees hot, melt hoses, water collectors or silencers. Suitable for 12 and 24 V on-board power supplies.
