<p>The present disclosure relates to an apparatus and a method for measuring load weight according to pressure compensation in accordance with temperature variation of a driving oil. The apparatus for measuring load weight according to the present disclosure includes: a lift cylinder; a pressure sensor mounted in the line of the lift cylinder and configured to measure the internal pressure of the lift cylinder; a temperature sensor mounted in the lift cylinder and configured to sense the temperature of the driving oil in the lift cylinder; and a control unit configured to compensate for, change, and set a pressure value under unloading and a pressure value under maximum loading, by a pressure compensation value determined in advance in accordance with the temperature variation of the driving oil that is sensed by the temperature sensor, and to measure the weight of the load by using the changed and set pressure values.</p> |
