Air preparation

AVENTICS™ Series AS2 Air Preparation Units

In the following, our team will present how an AVENTICS™ Series AS2 Air Preparation Unit works, what components our team possess, how we use and the way we have installed them.

In the pictures underneath one can see the parts that together build our air preparation unit.

You can find the general brochure that includes all the general information about the unit here.

It contains a multitude of different pieces and sets that Emerson makes and in the next part, the UPBAir team will present its equipment.

AVENTICS™ 3/2-shut-off valve, mechanically operated, Series AS2-BAV R412006257

The shut-off valve is used to power the system with compressed air from the tank or compressor.

Unlike a normal faucet, this aventics valve also removes the pressurised air from the system using a hole in the back of the module through a silencer.

AVENTICS™ Precision pressure regulator, Series AS2-RGP R412006148

A pressure regulator has the purpose of limiting the pressure at which the air is entering the system.

Using the black knob on the top, like a screw, the user can decide how much pressure to let into the system. The analog barometer indicates in real time the air pressure exiting the module.

AVENTICS™ Series AF2 flow rate sensor, IO-Link R412027176

The first such component we will present is the AVENTICS™ Series AF2 flow rate sensor, IO-Link R412027176. A flow meter (or a flow sensor) is type of flow instrument that is used to indicate the amount of gas moving through a pipe or conduit by measuring linear, non-linear, mass, or volumetric flow rates.

The way it can be assembled can be found here, while the instructions here.

Aventics cylinders

Aventics RTC-DA cylinder

Offers an optimized stroke length in a compact size, saving space.  The oval piston enables higher loads and torque, minimal leakage and a wide range of speeds for a better flexibility. The slide and piston as a single unit offers high load capacity and reliability. For more informations follow the link.

Aventics PRA MNR

Is a classical solutions for most applications including the heavy ones encountered in industries. It is lightweight and efficient. It also equipped with an adjustable pneumatic cushioning which reduces vibration and noise. The piston rod is made with 431 stainless steel which gives a higher resistance to corrosion. 
It is compatible with a range of accessories for the PRA series. In the laboratory the cylinder is anchored to the table using the CM1-MS1-050-M2-A foot mounting. Further informations can be found by following the link. The laboratory has 4 of these with different sizes: 
    - 40mm rod diameter, 500mm cylinder length
    - 63mm rod diameter, 320mm cylinder length
    - 50mm rod diameter, 320mm cylinder length
    - 63mm rod diameter, 500mm cylinder length

A Dive into Our Sensor Arsenal. Analog and Digital Sensors for IIoT monitoring and improvements

At The Smart Pneumatics Laboratory, we take pride in our commitment to innovation and precision in the field of pneumatics. Our laboratory is equipped with a diverse range of sensors that play a crucial role in our research and experiments. In this article, we invite you to delve into the fascinating world of pressure sensors, airflow sensors, air temperature sensors, as well as proximity inductive and magnetic sensors that form the backbone of our experiments.

Aventics AF2

By far our most prized sensor has to be the Aventics AF2. In out configuration using the IO-Link variant it can measure air pressure, air flow and temperature, two at a time. In most of our configurations it is placed right after the air preparation Aventics AS5 unit.

Our biggest project we used it in was to measure the energy of the compressed air entering the system to find out different configurations of pneumatic systems to improve energy efficiency.

Aventics PE5

This inexpensive and versatile pressure sensor can be placed anywhere in the pneumatic system to monitor air pressure. It connects using the same IO-Link cable like other sensors.

The biggest project it was used on it served the purpose to see the pressure drop at different points in different configurations of the same system to find the system with the highest efficiency.

Aventics SM6

This is a linear sensor that is placed on the side of Aventics PRA Pneumatic Cylinder and it outputs exact position within a 2^15 accuracy range (from 0 to 32767). They are custom selected for the different length of cylinders. We have one 500mm and three 320mm such linear senors.

The biggest project they were used on was to explore the variations in acceleration of cylinders using different configurations. The sensor gave us the exact distance the rod has traveled in a time frame and using the second derivative we could find out the change in acceleration of the rod. Obviously a smoother extension/retraction with close to zero acceleration is ideal.

Aventics ST6

The Aventics ST6 magnetic sensor is a proximity sensor purpose made to attach to Aventics PRA Pneumatic Cylinder to check the position of the inner magnetic rod. Unlike the other sensors, this one is digital and it is really easy to install.

This sensor has been crucial to first of all drive the cylinder back and fourth. Two of the them are placed at each end of the Cylinder to switch the valves to extend the cylinder or retract it.

In IIoT these sensors are a really simple and inexpensive (monetarily and easy to calculate) solution to find the extension and retraction speed of the cylinder.
