Dr. E. Horn Speed sensor FGL 01620

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.

The FGL 01630 has the following benefits for you:

Wide speed sensing range
Robust design
Contactless, thus, wear-free
Large air gap viable
Multifunctional sensing options.

We deliver directly and globally to end-users, agents, and resellers.

How does the speed sensor work?

The speed sensor FGL 01620 from 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.

The sensor detects ferromagnetic materials such as gear wheels and can handle modules of one and up to six.

The permitted system distance between the sensor and the gearwheel (see the technical specifications here) is bigger than average for air gaps. Thus, in combination with the fine thread pitch of 1 mm. a simple installation is secured.

The sensor signal is highly stable because of the differential measurement principle, and the square-wave signal voltage is available through a push-pull output stage.

Additionally, there is a smart sensor option available because even though the FGL01620 has been designed as a basic measuring unit it offers optional functions to be integrated such as temperature and/ or vibration sensing.

Typical Applications

The wide range of speed the FGL01620 can measure allows the sensor to be applied in various applications such as:

Marine Engines
Wind Power generation
Large gear units
Water turbines
Safety systems.

The Attributes of the Output Signal

With the single channel sensor, the output shows the rotational speed as a single-track frequency signal.

This is visualized in the picture on the left.

Different Options and available products

The FGL 01620 sensor is first and foremost used in combination with engine control system – systems which HORN develops themselves, as well as all the corresponding indicating instruments.

All can be developed and produced according to your specific needs and wishes. So, if you need to use the FGL01620 in a safety-level environment (SIL-level required) this is also available.

Moreover, different applicable products are available with this sensor like portable tachometers, speed indicators, and programmable converters for limit and alert settings.

How the Hall Effect Works in the FGL 01620 Sensor

The Horn FGL 01620 Hall-effect speed sensor provides precise, contactless RPM measurement by detecting changes in the magnetic field of a rotating ferromagnetic object. With a stable square-wave output up to 20 kHz, it ensures accurate speed monitoring across various applications, including marine engines, wind turbines, and industrial gearboxes. Its robust stainless-steel housing and large air gap tolerance enable reliable operation in harsh environments.

Designed for durability and efficiency, the FGL 01620 supports engine safety, process optimization, and predictive maintenance with optional temperature and vibration sensing.
