Abstract: An ultrasonic sensor detects whether a piston is at the lowest position. The sensor is not affected by the environment or damaged by contact with other objects. The sensor is located in the bottom of a mast cylinder, transmits ultrasonic waves to the bottom of a piston and receives ultrasonic waves reflected by the piston.

The transmitter-receiver includes an ultrasonic wave generator and sends ultrasonic wave transmitting signal having a predetermined frequency to the ultrasonic sensor based on control signals from the controller. The controller measures time from when it outputs the ultrasonic wave transmitting signal to when the sensor receives a reflected wave. The controller then compares the measured time with a threshold value thereby judging whether the piston is at the lowest position.
