RFID operating principle

Phoenix Contact offers a comprehensive product range for contact-free system and device marking via RFID technology. With the RFMARK reader with HF or UHF technology, you can write marking material with integrated RFID transponders without contact.

You may use Radio-frequency identification (RFID) for contact-free identification, data exchange, and localization of transponders/tags without visual contact. With the aid of an RFID handheld device, which acts as a transmitter and receiver, data is transmitted to and received from a transponder/tag by electromagnetic waves (UHF) or a magnetic field (HF).

RFID is used in Power plant identification

When it comes to RFID technology, a distinction is made between active and passive transponders (transmit and response). The fundamental design of an RFID transponder consists of an antenna, a microcontroller, and a permanent memory that can be read and written. In order to ensure optimized maintenance, passive transponders that do not have a seperate battery supply tend to be used in power plants.

In the case of passive transponders, a distinction is made between high frequency (HF) and ultra high frequency (UHF) transponders. The HF transponder is excited at a frequency of 13.56 MHz, e.g, using a handheld device. It therefore reaches a maximum distance of 1 m. The UHF transponder, which has a frequency of 868 MHz (central Europe), is suitable for larger distances of up to 4 m. Both transponder types are used in power plant applications:

  • Since for electrical equipment clear identification is the primary aim, greater distances and the associated bulk detection are not possible here. In the case of bulk of bulk detection, all RFID transponders within range of the handheld device are detected.
  • In the case of mechanical structures and large units, it is more practical to use UHF transponders due to the inaccessibility of some areas. Bulk detection of multiple RFID transponders is certainly a possibility here.
