1. A speed sensing device adapted to attach to a hydrostatic motor, said hydrostatic motor being a hydraulic motor connectable to a hydraulic pump in a high-pressure circuit and having a motor housing, comprising:

  • a sensor housing attachable to the motor housing of the hydrostatic motor;

    a sensor coupled to the sensor housing for sensing the rotational speed, including angular velocity and direction, of the hydrostatic motor;

    a microprocessor disposed within said sensor housing and connected to the sensor for receiving and processing the sensed rotational speed of the hydrostatic motor; and

    a connector coupled to the sensor housing for connecting the microprocessor to an external device to send and receive signals from the external device.
