APPLICATIONS
Mine Pit Conveyer Belt – By integrating the LE PT X into the proportional hydraulics you can smoothly operate the startup of the conveyer system to minimize aggregate spillage.
Agriculture Crop Sprayer – The LE PT X offers precise control of the arms of a crop sprayer as it lifts and lowers.
LE PT X
A dual driver with a digital display in a potted enclosure.
The LE PT X supplies a solenoid with current proportional to the input signal from a potentiometer, joystick, PLC or other control system. These amplifiers allow for a smooth operation for any proportional application and can be used with any proportional valve brand including; Sun Hydraulics, Parker, Bosch Rexroth, Vickers, Denison, Yuken, Argo-Hytos, etc. The LE PT X is fire and shock resistant making it an ideal unit for rugged applications.
