Discrete output proximity sensors are most important for industrial applications. They gain importance in such applications where it is necessary to record or count moving objects or work-pieces on machines or conveyors. Based on the connection of the final output amplifier transistor of a discrete proximity sensor to the power supply terminals, proximity sensors can […]
As you are aware, a pneumatic system is an interconnection of various components such a compressor, actuators, control valves, and other elements using fluid conductors. The operation of the pneumatic system is affected by the presence of heat, dust, moisture, leaks, loose bolts, and misalignment in the system. Lack of regular maintenance may result in […]
Seals (or packings) are deformable materials sandwiched between the mating surfaces to close of small gaps. They retain fluid under pressure within the system and keep foreign matter out. They prevent the metal-to-metal contact of sliding surfaces. They are made from polymer materials that are flexible (rubber) and soft (plastics). The elastomeric quality enables them […]
An electro-pneumatic system, in general, consists of an electrical or electronic control part controlling a pneumatic power part. Integrating the power density of pneumatic systems with the controlling possibilities of the electric systems opens up a new world of opportunities for the high-performing pneumatic systems. In this hybrid technology, solenoid valves are used as interfaces […]
The cleanliness of hydraulic fluids needs to be monitored for maintaining the components of hydraulic systems at a satisfactory level. Many national and international organizations such as ISO, SAE, National Aerospace Standards (NAS), etc., have developed standards for specifying the particle size classification and contamination concentration levels in hydraulic fluids. All standards specify the contamination […]
The primary goal while designing a hydraulic system is to use less energy and do more work. A conventional hydraulic system with a fixed-displacement pump provides a constant flow through the system. The maximum system pressure is limited by the settings of a pressure relief valve in the system. When the load demands less flow […]
The most common valve configurations used for hydraulic control systems range from the discrete valves controlled by the electromagnets to infinitely variable valves, controlled by the special proportional electromagnets (or torque motors). Proportional valves are devices for obtaining the finely variable flow and pressure controls using proportional electromagnets. They were developed as a low-cost alternative […]
