Sensor Reduces Costly Losses


Emerson today introduced the Aventics AF2 pneumatic systems flow sensor which monitors energy losses which helps to prevent machine breakdowns and costs associated with excessive air consumption. The sensor continuously monitors the air consumption in pneumatic systems enabling compliance with the Energy Management standard DIN ISO 50001. Suitable for use in many industries, the device is just one of many components available from Emerson for networked plants in factory automation, known as the Industrial Internet of Things (IIoT).


An Organic Light Emitting Diode (OLED) display on the AF2 provides local indication of all relevant operating and diagnostic data. The flow sensor is available as a NO (normally open) and NC (normally closed) version. Analog outputs can be switched with a signal from 4 to 20 mA. These signals can be interpreted directly by many controllers.  Another possibility for communication is the IO-Link capability of the sensor and the Ethernet interface, enabling customers to use the optimum device to communicate with existing controllers. OPC UA (Open Platform Communications Unified Architecture) and MQTT (Message Queuing Telemetry Transport), the preferred communications protocols for industry 4.0, are integrated into the AF2 sensor. In addition, the AF2 has a web-based dashboard showing real-time data for the users.


Modular construction ensures easy installation, and small dimensions mean it can be installed where space is limited. The Aventics AF2 is delivered pre-calibrated together with its filter. This saves space as no separate stabilization distance is required. Furthermore, the sensor-filter combination can be configured in any maintenance unit. The flow sensor is suitable for all common applications and industries such as food and beverage or packaging.
