Marine approved pressure sensor for use on lube oil up to 10 bar with a maximum media temperature of 125°C and environment temperature of 85°C. Monitor critical lube oil pressure in demanding marine environments with this robust and temperature tolerant sensor.
The DMK457 marine-approved pressure sensor is designed for use in critical ship engine lubrication systems. Engine lubricating oil pressure is a vital parameter to monitor, as it ensures the smooth and efficient operation of a ship’s engine. This sensor is specifically engineered to provide reliable pressure measurements in demanding marine environments, where its robust design is essential for ensuring the safe and efficient operation of the vessel.
Unlike standard industrial pressure sensors, the DMK457 is built to withstand the harsh conditions encountered at sea, such as vibration, humidity, and salt spray. It is designed to provide stable and reliable performance in these conditions, ensuring that engine performance is not compromised. The sensor’s ability to measure pressures up to 10 bar makes it suitable for a wide range of marine engines. In addition, the DMK457 is compatible with a variety of lube oils, making it a versatile choice for use in diverse marine applications.
By utilizing the DMK457 pressure sensor, ship operators can ensure the longevity and efficiency of their engines, reduce maintenance costs, and improve the overall safety of their operations.
