Speed Sensor Kit for Borg Warner EFR Turbochargers – Part No. 179430
Comprises:
1x Speed sensor, frequency output;
1x Speed sensor hold-down bolt
The speed sensor is powered by a +5V supply, and the return signal is a
variable frequency square wave that has a maximum amplitude of 5V and
has a 50% duty cycle. The frequency of this signal depends on the
speed of the wheel. Each passing blade creates a pulse, and all the EFR
wheels have 14 blades except for the 67mm (which has 12 blades). The
sensor-embedded electronics divides the blade-pass frequency by 8, and
then the resulting count forms the output waveform. Here is an
example:
100,000 rpm * 14 blades/rev = 1,400,000 blade pass counts per minute
1,400,000 / 60 sec/min = 23,333 blade pass counts per second (Hz)
23,333 / 8 count divisor = 2,917 Hz output frequency
