ACP303 – the Pneumatic Cylinder Actuator developed by SMAR is the equipment that responds to the growing industry needs, mainly related to the applications on pneumatic cylinders control.

The ACP303 combines the strength of pneumatic cylinders with the potentialities of the FY intelligent micro-processed positioner, which allows for modulated control applications. The ACP modular structure allows for its being mounted on a wide variety of cylinder sizes, by using a single version of mounting support. The Pneumatic Cylinder Actuator (ACP303) is available in several sizes according to the required function and travel. There are two types of models: linear or rotary, for different operation travel.

Through the action of the FY301 positioner, the position of the pneumatic double action cylinder is controlled with the use of the linear or rotary magnet system via-Hall effect. This positioning system, overcomes one the biggest disadvantages of the pneumatic action, namely, obtaining intermediary cylinder stops. More than simply taking the micro-processing to the cylinder, the ACP303 is presented in its linear and rotary versions, which gives the user freedom of application on several final control elements, such as dampers (for oven batch control), water dams, large valves and other applications that require control of movement.

The ACP303 receives a signal on the PROFIBUS PA standard protocol emitted by the controller who activates and directs the cylinder to its exact position, as required, and compliant to the strategy and tuning of the control loop on which it is applied. By including intelligence in the cylinder, the ACP303 allows for the user to configure the feature of opening the cylinder with the control signal received.

Furthermore, the easy use of the PROFIBUS communication protocol in a few minutes provides a simple interface between the field and the control room, and multiple features that reduce installation, operation and maintenance costs:

  • Compact and modular project;
  • Easy to install;
  • Non-contact position measurement via Hall Effect sensor;
  • Simple parameter configuration through local controls and indicators;
  • Weather proof, explosion proof, intrinsically safe;
  • Change of valve opening characteristic via software;
  • Auto-configuration in a few minutes;
  • Auto-lubrication with no need for external lubricants;
  • Optional limits switches;
  • Filter regulator incorporated.
