RFID Sensors

filter_list

RFID sensors, or Radio Frequency Identification sensors, are used widely across various industries for tracking and identification purposes. These devices utilize electromagnetic fields to automatically identify and track tags attached to objects. The tags contain electronically stored information which can be read from a distance, making RFID technology particularly useful for supply chain management, inventory control, and access control systems.

RFID sensors can be passive, active, or battery-assisted passive. Passive tags collect energy from a nearby RFID reader's interrogating radio waves, active tags have their own power source, and battery-assisted passive tags use a battery to power the tag's radio chip, thereby increasing its range. This technology is beneficial not only because it enables automatic and accurate data collection and storage, but also because it minimizes the need for manual entry and the potential for errors associated with it.

Analog and Digital Control Signals: The Basics

Digital Signals

Digital signals are represented in either a true or false. There is no gray area with digital signals. An example of this might be a light switch. A light switch is either on or off. Another example of this might be a motor that is running or not running. Digital signals can be generated with both AC and DC circuits with varying voltages, currents and resistance. Some practical examples of using digital signals in an industrial environment might be if a pump is running or not running or a whether a valve is open or closed.

Analog Signals

Analog signals convey information in the form of a range. A light switch might be on or off as a digital signal, but a dimmer switch would be an analog signal. It can be on or off, but it can also be somewhere in between. A practical example of using analog signals in an industrial environment would be if there is a need to measure the level of a tank; whether it's full, empty or somewhere in between. Analog signals can take many different forms with some of the more common being a 4 to 20 milliamp signal or a 0 to 5 or 0 to 10 volt signal. 

Communication

Communication in a device can either be sent or received. Whether that data is sent or received depends on the type of information. Is there a need to monitor the status of something? If so, an input needs to be received about that information. Is there a need to control something? If so, an output needs to be sent about what needs to occur. Receiving inputs and setting outputs are both things that can be accomplished by using both digital and analog signal types. Therefore, the signals are referred to as analog outputs (AO), analog inputs (AI), digital inputs (DI) or digital outputs (DO).
