Multiples WiO-Setup
After the successful introduction of the 4th generation of our WiO sensors last year, the update and further development at system level now follows: The multiple WiO setup with central monitoring unit. For parallel monitoring of up to six WiO sensor systems.
This setup allows flexible monitoring of several plants with regard to moisture in oil and the respective current media temperature. The evaluation of the analog values takes place separately for each plant and is triggered in each case by an individually adjustable pre-alarm and main alarm. On the basis of time trend curves, which can be viewed and analyzed for each channel via touch on the display, the user is able to take immediate measures on the plants or to plan them in advance.
An example? Monitoring of the drives of a seagoing vessel: one main unit with five auxiliary units. The individual sensors FRG00035, connected to the MPU010 boxes, are connected to the central display unit. - For detailed information, please contact us directly.

New representation for Singapore, Indonesia and Malaysia
We have the pleasure to announce that we signed a representation agreement with Company Twinco PTE Ltd. in Singapore for the market areas covering Singapore, Indonesia and Malaysia. Contract had been signed in Dec. 2021 in our factory.
Both companies know each other well, as for many years a fruitful sales cooperation has been established. Additionally, besides the spare part sales, business focus is now made on building up a service station for our 2-stroke bearing monitoring systems, 4-stroke oil mist detectors and other technical products.
Singapore is considered to be an important service hub as a high no. of vessels are sailing in this area and several fleets are managed from this region.
We wish company Twinco a good start into the new service era with our high sophisticated electronic Products.

Dr. E. Horn launches new sensor system
Ready to go live: Our newly developed Cylinder Liner Temperature Sensor System CLTS continuously observes 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.Â
The sensors show a highly robust design: Sensor tip can withstand and detect temperatures from -40°C 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. Thus, excellent thermal response will be provided and short reaction times are secured in case of overheating.
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 inside the liner.
CLTS sensors are equipped with an evaluation board, assembled in housing GHG02731. Outgoing communication will be provided as current loop 4...20mA or I²C. This makes the CLTS system a flexible solution also for monitoring temperatures in large gear units as well as plain and ball bearings of heavy-duty drives.Â
Let us know your application – sure we will find the perfect solution!

Our specialty: Enabling mature mechanical plant technology with smart electronics
Target applications – proven mechanical engineering solutions, often optimized over decades.Â
The focus of market interest today is well known: mass data acquisition, continuous condition monitoring, ongoing real-time evaluation of data with determination of maintenance cycles. Both aspects are evaluated: Analysis of temporal trends as well as detection and processing of short-term, non-linear events
What's an example? Continuous monitoring of filter units in municipal pool pumps. The aggregates ensure sparkling-clean water quality and are therefore subject to a scheduled cleaning interval. With the help of smart electronics, the degree of contamination is measured inline and a message is sent to the staff when a threshold value is reached. – Benefits: Increase of plant efficiency (and thus also of water quality) and reduction of manual effort, since down times are controlled according to real demand.Â
We are happy to support our customers in integrating smart solutions into their existing product portfolio. Together with our team of own developers, we find solutions that are tailor-made to your requirements: from first concept sketches to series production. Our strength lies in the personal support and the flexible possibilities of a mid-sized full-service provider.
With more than 100 years of development and production experience of single sensors, display systems as well as complete measuring and control systems, Dr. E. Horn is a competent and reliable manufacturer in the market. Let us convince you of our performance and partnership.

Dr. E. Horn launches new generation of RPM speed sensors
The speed sensor series FGL01620 has been developed for very flexible use: Extremely low speed -near full stop- can be detected as well as highspeed rotations up to 20kHz frequency. This wide range allows the FGL01620 type to be applied in multiple applications: industrial turbines, heavy industry gearbox units, wind power generators and large-scale engines.Â
The robust stainless steel design makes the FGL01620 a preferred sensor in offshore and marine applications. The sensor detects ferromagnetic materials such as gear wheels and can handle modules of 1 to 6. Our development competence is shown by the specifications for the air gap: The permitted system distance between the sensor and the gearwheel is larger than average and therefore -combined with a fine thread pitch- simple installation is ensured.
The square-wave signal voltage is available via a push-pull output stage. Sensor signal is extremely stable due to differential measurement principle.Â
Smart Sensor option: The FGL01620 speed sensor has been designed as a basic measuring unit. On request it offers optional functions to be integrated such as temperature and vibration sensing.

Working Group MTP
The networking of the various systems — including the various propulsion systems — on the ship and the networking between ship and port represents a considerable challenge both for the commissioning and for the operation of the ship.
