Turbocharger speed sensor FGL 1/16

The speed sensor FGL 1/16 from 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.

To achieve a high signal-to-noise ratio the sensor uses different parts, where each measurement task requires a distinct measurement principle, including:

Compatible output levels
Shielded cables
Plug connectors.

Turbocharger speed sensor FGL 1/16

This particular sensor is designed to detect various objects made of ferromagnetic material, such as:

Gear wheels
Punched discs
Pins
Integral shafts.

It comprises a magnet and a coil wrapped around an iron rod, generating a voltage that corresponds to the frequency of the object's movement. By adjusting the distance between the sensor top and the object, the inductive sensor produces an output voltage that is strongly influenced by the object's:

Speed
Peripheral speed
Tooth structure (module)
The gap between the gear and the sensor.

It's crucial to note that for a gear with 60 teeth, module 2, and a speed of 15 rpm, the gear-to-sensor distance should not exceed 0.5 mm. When the peripheral speed decreases, the gear-to-sensor distance should be reduced, and vice versa. This relationship can be approximated using equation (1) within the range of s = 0.4 to 1.0 mm and m = 2 to 4.

For other objects like pins, holes, or different tooth forms on a shaft, equation (2) is applicable when their dimensions surpass those of a gearwheel with module 4.

When calculating the minimum speeds using this method, the approximate signal voltage is around 0.4 Vpp.

Explaining the shortenings:

n = lower limit of speed measuring range in rpm

m = module of the sensed gearwheel

z = number of teeth on sensed gear wheel

s = distance between pulse sensor and tip of the gear in mm

d = tip diameter in mm

Other available Inductive Pulse and Speed Sensors

Below we have gathered the HORN selection of pulse and speed sensors. If there is a specific kind you need, which is not found here, please do not hesitate contacting us here.

The Inductive Pulse Sensor with Amplifier: FGL 01406

The measurement principle and framework conditions for the FGL 1/... pick-ups apply to the FGL01406-.. sensor as well. However, the FGL01406-.. sensor offers a square wave signal output (PNP), ensuring safety against incorrect polarity and short circuits.

With their robust design, these pick-ups are ideal for applications in combustion engines and high-vibration machinery. They have obtained approvals from recognized classification societies.

Speed sensor FGL 01620

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 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.

Speed Sensor FGL01364

The FGL 01364 from HORN is an inductive phase sensor with amplifier, which is ideal for sensing objects such as:

Gear wheels
Punched discs
Integral steel shafts.

It features a coil with an oscillator circuit and amplifier. By adjusting the air gap between the object and sensor tip, voltage changes in the coil/oscillator system are detected and evaluated.
