Dr. E. Horn GmbH & Co. KG

The Dr. E. Horn Bearing Monitoring System is well known for more than a decade of years. Since year 2008 more than 2400 systems are in service for monitoring the wear of bearings. The BMS3 realizes a continuous surveillance of an engine in regard to the distance between sensor and cross head in its lower dead point position, which is a measure of the bearing wear. Further, it monitors the temperature of the oil in different positions as well as the solved water content in the oil (Water in lube Oil). As an option the system offers a precise temperature observation of the cylinder liners. The new version is answering requirements for open data supply handled by modern interfaces.
The BMS3 is using latest hardware and supplies data from terminal boxes up to the HMI by Ethernet. HMI form customers can easily be connected as main unit supplies data by using a web browser. A dual core controller concept separates internal and external communication. Last but not least a cost down program had been run through as a reaction to the risen market prices for electronic parts

Cylinder Liner Temperature Sensors continuously observe the temperature level of each liner in a marine engine aggregate. The aim is to detect defects at an early stage and to protect the cylinder liner from irreparable damage. Each liner will be equipped with a pair of sensors, both installed in opposite direction. This supports to determine the worst case temperature level no matter installation tolerances and air gaps inside the liner. The sensors show a highly robust design: Sensor tip can withstand and detect temperatures up to 800°C whereas materials in use are of stainless steel. Inside the sensors there is a spring mechanism which allows the sensor tip to move – and therefore to guarantee the constant mechanical contact between sensing element and cylinder liner. This will provide excellent thermal response and short reaction times in case of overheating. Further reading

After the successful launch of the 4th generation of our WiO sensors last year, now follows the update and further development on system level: Multiple WiO Setup with central monitoring unit. For parallel monitoring of up to six WiO sensor systems. This setup allows flexible monitoring of multiple installations with regard to moisture in oil and the respective current media temperature. The evaluation of these analog values is carried out separately for each unit and is triggered in each case by means of an individually adjustable pre-alarm and main alarm. Based on time trend curves, which can be viewed and analyzed for each channel via touch on the display, the user is able to take immediate actions on the systems or plan them in advance. What‘s an example? Monitoring of maritime ship propulsion: one mains and 5 auxiliaries. Single sensors FRG00035 connected to MPU010 boxes which will then be linked to the central displaying unit. – Please refer to us for detailed information. Further reading
