Wireless communication

Technology for Industrial Applications

Wireless communication technology
facilitates our lifestyle in every aspect. It
can save our time, and decrease potential
mistake and labor force so that we can
spend our time on something more
important. There is also the utilization
of the technology among industrial
communities.

Types of W ireless The Advantages toward Weighing Scale
Communication used in Today these technologies (RF, WIFI, and Bluetooth) have been developed to apply with a weighing
The Industry scale in order to simplify its performance, decrease potential mistake, and save time and the process.
1. Radio Frequency (RF), the For example, if the LAN wiring to send the weighing data to computer is troublesome, the utilization of
frequency range from around 20 kHz the technologies will be the best solution. When the user understands the purpose of weighing and
to around 300 GHz, can be applied choose the correct indicator to suit with application and environment, with the technologies above he

application depends on the frequency
and on site environment. If there is
an obstacle or a thick wall, it may
shorten and disturb the transmittance.
2. WIFI or Wireless Local Area
Network is a short transmittances for
a limited area. The equipment which
can use WIFI is a mobile phone
which can be used from 20 meters
distance. Moreover, it can be
amplified with the connection to the
access point.
3. Bluetooth is the shortest
wireless communication. There are The Application of Weighing Scale with The Technologies
5 classes as per below. The weighing scale with these technologies can be applied in both normal area and hazardous area.
• Class 1 Max. permitted power In hazardous area, to limit the amount of workers is tremendously significant because it can decrease

2.5 mW. estimated range 10 m. To invest in wireless communication technology will be a big benefit. It can decrease a loss from
• Class 3 Max. permitted power unpredictable danger within production line and decrease the production cost. Moreover, it can also
