The Pneumatic Actuator Valve for the Controlling Mode

The old-style pneumatic actuators mainly consists of a pneumatic setup that features a heater inside the reservoir and surrounding it so as to ensure a constant old-style pneumatic actuator temperature. Therefore, the temperature can be measured near the reservoir outlet in a closed control loop in spite of the fact that the entire pneumatic actuator system entails two pressure controllers in order to adjust the actuation pressure of the system. On the other hand, it has been proven that the old-style pneumatic actuator valve for the controlling mode without any doubt can be applied with the help of hall sensors to obtain the field and the mean values that will not be influenced by the frequency variation even though the maximum and minimum values of old-style pneumatic actuator force and magnetic field tend to approximate the mean value with the increasing of the working frequency. Moreover, according to scientific research results, a peak in the pneumatic actuator force can be noticed, which reveals the fact that the natural frequency of the mechanical system will increase the amplitude acquired on the basis of the imposed displacement.

As a matter of fact, this phenomenon can be detected by old-style pneumatic or electric actuators hall sensors because they are able to measure the flux density on the system and thus they are insensitive to a varying air gap. In order to verify the dynamic of the whole old-style pneumatic actuator system, the mechanical model has to be taken into account with the main focus to investigate the design of a low-cost contact free new type pneumatic actuator by taking the following steps. With respect to the design of the new pneumatic actuator, it is a truth universally acknowledged that surfaces round and flat actuator poles as well as previous advantages of the old-style pneumatic actuator can be applied to different shaft diameters in spite of the fact that pneumatic actuator accuracy depends on the ratio of actuator end and shaft diameter dimension.

And to be more specific, the air gap as well as current has an influence on the pneumatic actuator forces according to simulations and experiments due to the flexible rotor motion that will lead to an interaction between different pneumatic actuator parameters in comparison to the measured results of air-gap that has to be monitored to achieve accurate results. Much better results concerning the pneumatic actuator can be achieved by the application of hall sensors to measure the field density inside the poles without calibration or signals. The value of achievable old-style pneumatic actuator force will then be dramatically reduces in the coil of the circuit, which will limit the feasible frequency range of operation in some working conditions.
