Technical Information
Speed and Temperature Sensor for Hydrostatic Propel Products
General Information
Description
Function of the speed sensor is to detect the shaft speed. Typically the sensor is mounted to the housingof a Danfoss pump or motor and senses the speed from a target ring that is rotating inside the pump or
motor.
Because of the digital output signals for speed the sensor is ideal for high and low speed measurements.
The speed sensor is designed for rugged outdoor, mobile or heavy industrial speed sensing applications.
The detection of the speed is contactless. It is custom-designed for Danfoss. It is a Plug and Perform device
that does not need any calibration or adjustments.
For diagnostics and other purposes, some sensor also has the capability to detect the driving direction
and the case oil temperature.
Theory of Operation
The speed sensor is externally powered and, in response to the speed of the target ring, outputs a digitalpulse signal. A magnet inside the sensor provides the magnetic field that changes with the position of
the target teeth.
The target ring is attached to the cylinder block or the shaft. Hall sensors change from high/low state as
the target teeth pass by the sensor´s face. The digital (on-off-on-off ) pulse train is fed to a controller,
which interprets its rate of change as a speed.
Some speed sensor uses two Hall sensors with specific distance and orientation resulting in a pulse train
output shift of 90° between the two sensors. A logic circuit decodes the two signals to provide an
additional direction indication (high or low depending on direction).
Due to the design of the sensor, the duty cycle (ratio between on and off time at constant speed) of bothspeed signals at any working condition is close to 50 % and can be used for better resolution at low
speeds.
Speed Rings
Speed (target) rings vary according to the diameter of the cylinder block or shaft on which they are
installed. The number of teeth is shown in the table below.

Wire Fault Detection
The output voltage levels are defined for a direct connection of the sensor to supply. The outputs are
directly connected to a load which is 15k Ohm to ground and 15k Ohm to Supply.
The signal outputs are protected by an 1100 ohm (1k1) resistor. Speed signal 1 (pin 3) offers an advanced
error detection by providing different signal levels in case of an error.

The output voltage levels are defined for a direct connection of the sensor to supply. The outputs are
directly connected to a load which is 15k Ohm to ground and 15k Ohm to Supply.
The internal voltage regulator will limit the output signal to max. 24V in high state. The output is
protected by 680 Ohm resistor. The pull-up resistor to supply is 2k7 Ohm.
This circuitry will generate voltage levels per condition as follows (typical outputs shown for referenceonly):
