Hydac/Hedec HDA 7446 electronic pressure transmitter

Hydac/Hedec HDA 7446 electronic pressure transmitterIntroduction:

HYDAC was founded in 1963 and is Saar's hydraulic parts company. Today, we are an active, owner managed group of companies with over 9500 employees specializing in the manufacturing and sales of components and systems, as well as services in industrial and mobile hydraulic, fluid technology, and electronic control technology.

HYDAC stands for Hydraulic, Systems, and Fluid Engineering.

HYDAC components can be found in all fields of industrial and mobile hydraulics. The HYDAC solution can cool and lubricate the gears in wind turbines, work in the tensioning hydraulic system of modern machine tools, provide cushioning for the cab of agricultural machinery, support the working hydraulic system of excavators, and inspect and test the load capacity of Airbus A 380 wings.

The HYDAC unit can adjust the parabolic groove of solar power plants or start the valves and armatures of power plants. The vibration of large diesel engines is dampened by hydraulic accumulators, and the shaft movement on drilling ships is compensated for by hydraulic cylinders.

Our supply planHydac/Hedec HDA 7446 electronic pressure transmitterIncluding hydraulic accumulator, fluid filter, process filter, cooler, electro-hydraulic control/industrial valve, pressure sensor system, encoder measurement and solenoid technology, hydraulic cylinder, pump, installation technology, armature, status monitoring, etc.

system capability

We plan and provide ready to use hydraulic control and drive systems, including electronic controls and regulators for mobile and fixed machines and factories used in various industries.

For this purpose, we rely on years of experience and engineering support to design complex electric hydraulic drive systems. The feeling of liquid, as a design element, requires special attention to the fluid. Solutions related to hydraulic and lubrication systems have always been our area of expertise.

The properties of lubricants greatly affect the functionality of friction systems. Fluid monitoring and corresponding fluid maintenance can provide guarantees for the functionality, availability, and service life of industrial systems in fixed and mobile hydraulic technology as well as lubrication technology.
