Most machinery failures give warning before they occur. A crankcase explosion does not. Oil mist concentration can rise from normal to dangerous in minutes, and without detection, the first indication is the event itself.

Engine safety systems protect against the failure scenarios where consequences are severe enough that no warning is acceptable. They detect, alarm, and where necessary shut the engine down before the situation becomes unrecoverable.

Our range covers the critical protection disciplines for main and auxiliary marine diesel engines: oil mist detection, bearing distance and temperature monitoring, crankcase pressure measurement, speed and phase sensing, and water-in-oil detection.

ODM HORN 1024 Square Front

MEV283 Series

Dr. E. Horn Oil Mist Detector MEV283

The Oil Mist Detector from Dr. E. Horn is a compact system, which can detect even the smallest changes in the oil concentration and is connected to the vessel’s automation security system. Moreover, this system can be retrofitted and mounted directly on the pipes for crankcase ventilation. Thus, no additional pipping is required in the assembly.

2 Stroke Bearing Monitoring HORN 1024 Square Front

BDMS

Dr. E. Horn Bearing Distance and Temperature Monitoring System

The Bearing Monitoring System from Dr. E. Horn makes continuous surveillance of your engine in relation to the distance between the sensor and the cross hear in its lower dead point position, which is a measure of the bearing wear. One of the key benefits of the 2-stroke bearing monitoring system is improved reliability. By detecting potential issues early, operators can take proactive measures to prevent failures and minimize downtime.

Pressure Sensor

Dr. E. Horn Pressure Transmitter TGL014xxx

The pressure transmitter TGL014xxx from Dr. E. Horn is designed for measuring the absolute and gauge pressure of various liquids including gas and vapors. In general, the pressure sensor from HORN measures the pressure occurring in the engine compartment against the atmosphere. The piston defects can be detected by the means of this pressure measurement; thus, it is an essential variable in the assessment of the smooth operation of your engine.

Speed Sensor

Dr. E. Horn Speed Sensor FGL 01620

The speed sensor FGL 01620 from Dr. E. Horn can be used both at extremely low speed, and almost full stop can be detected, and it is also applicable for highspeed rotations up to 20kHz frequency. It is a preferred sensor for offshore and marine purposes because of its vigorous stainless-steel design.

FRG00032 1024 Square Front

Water in Oil Sensor

Dr. E. Horn Water in Oil (WiO) System FRG00032

The Water in Oil system from Dr. E. Horn consists of a sensor FRG00032, a connection box GHG02088-5, a connection cable KSG03244-1, and three relay outputs. Additionally, to the basic standalone version, is the option to get an analogue output for water content and oil temperature, as well as an indicator box with analog indicator(s), operating devices, and an acoustic alarm.

FGL1 16 Speed Sensor HORN 1024 Square Front

Turbocharger Speed Sensor

Dr. E. Horn Turbocharger Speed Sensor FGL 1/16

The speed sensor FGL 1/16 from Dr. E. Horn is composed of a metallic housing that contains the sensor components and, in some cases, the electronic components. This design ensures mechanical durability and prevents interference from external circuits.

FGL01406 Horn 1024 Square Front

Inductive Pulse Sensor

Dr. E. Horn Speed Sensor FGL 01406

The speed sensor FGL 01406 from Dr. E. Horn is composed of a metallic housing that contains the sensor components and, in some cases, the electronic components. This design ensures mechanical durability and prevents interference from external circuits.

FGL01364 Horn 1024 Square Front

Inductive Phase Sensor

Dr. E. Horn Speed Phase Sensor FGL01364

This FGL 01364 from Dr. E. Horn is an inductive phase sensor with an amplifier, which is ideal for sensing objects such as gear wheels, punched discs, and integral steel shafts. It features a coil with an oscillator circuit and amplifier. By adjusting the air gap between the object and the sensor tip, voltage changes in the coil/oscillator system are detected and evaluated.

FGL01612 HORN 1024 Square Front

Magnetic Field Sensor

Dr. E. Horn Magnetic Field Sensor FGL01612

The FGL01612 from Dr. E. Horn is a sensor used for measuring magnetic fields. The sensor is used in combination with two other devices: the pulse amplifier (EV299013) and the magnet (MG003272).

How to Choose

Oil mist detection is the starting point for most vessels — and a class requirement for many. If your main engine is above 200mm cylinder bore, confirm your compliance status before anything else.

Bearing distance monitoring is the logical next step for 2-stroke engines where crosshead bearing wear is a known risk and where oil analysis alone is not sufficient for early detection.

Speed, pressure, and phase sensors are typically specified during newbuild or refit, or as replacements for existing sensors that are approaching end of service life or are no longer supported by their original manufacturer.
