Operation device and hydraulic system
First Claim
1. An operation device comprising:
- an operating unit;
a pilot valve that outputs a pilot pressure corresponding to an operating amount of the operating unit;
an operating amount detection sensor that outputs an operating amount signal corresponding to the operating amount of the operating unit;
a first bar code provided on the pilot valve and containing pilot pressure actual measurement information indicating a relationship between the operating amount of the operating unit and an actual measurement value of the pilot pressure outputted from the pilot valve; and
a second bar code provided on the pilot valve and containing operating amount signal actual measurement information indicating a relationship between the operating amount of the operating unit and an actual measurement value of the operating amount signal outputted from the operating amount detection sensor.
