Load sensing is a term used to describe a type of pump control employed in open circuits. It is so called because the load-induced pressure downstream of an orifice is sensed and pump flow adjusted to maintain a constant pressure drop (and therefore flow) across the orifice.

Load-sensing describes a type of variable pump control used in open circuits. It is also termed this because the load-induced pressure downstream of an orifice is sensed and pump flow is adjusted to maintain a constant pressure drop (and therefore flow) across the orifice.

Technically, it is called a Pressure-Flow Compensated Variable Volume Piston Pump. What is Load Sensing? Very simply stated, it is a hydraulic system that senses and provides only the pressure and flow required by the hydraulic system.

Load sensing is a sophisticated hydraulic system technology that optimizes hydraulic flow and pressure based on the demands of the task. It works by continuously monitoring the load conditions and adjusting to provide precisely the right amount of hydraulic power needed.

2013年7月26日 · with a disconnected or inoperative Load Sensing System. The JLG-designed Load Sensing System (LSS) measures platform load. If the actual platform load exceeds the selected Rated Load, the following will occur: 1. The Overload Visual Warning Indicator will flash at the selected control position (platform or ground). 2.

2017年8月7日 · The hydraulic system with a load sensing feature provides only the flow and pressure required by the connected load. Controlling both the pressure and the flow allows for a significant reduction in losses, improvement of circuit efficiencies, and enhancement of the system's service life.

Load sensing is a hydraulic system technology that automatically adjusts the hydraulic flow and pressure to match the demand placed on the system. It works by continuously monitoring the load conditions and providing just the right amount of hydraulic power needed for the task at hand.

When someone says a system is “load sensing,” it means that it has been designed to operate at as low a flow and/or pressure as possible when no functions are actuated, and is able to immediately “jump” back up to the flows and pressures necessary to do the work demanded.

Load sensing system Hydraulic control system able to adjust pressure and flow rate to reflect the requirements of one or more consumers at any given time. LS systems can be created using a constant pump as well as a variable pump .

A load sensing circuit typically comprises a variable displacement pump, usually axial-piston design, fitted with a load sensing controller, and a directional control valve with an integral load-signal gallery (Exhibit 1).
