visualisation software, SKF @ptitude Observer, can be installed on a local server at
the customer location or as a cloud solution.
System considerations and architectures
The sensor – gateway interface is a radio system for wireless mesh networks with a
low power consumption and support for over-the-air (OTA) firmware updates. It is
specifically designed to enable reliable communication in congested wireless
environments and can identify and adapt to changes it has detected. The radio
operates on the 2.4 GHz ISM (Industrial, Scientific, Medical) band.
Whilst the wireless range will be dependent on plant topology, being a mesh system,
relay nodes can be deployed or outlying sensors can rely on the sensor mesh rather
than direct sensor/gateway communication. This assists in industrial environments
where a line of sight connection may be restricted or where sensors are situated
across wider areas. As a minimum, the system has been designed to support a
topography where there are up to 10 node jumps from the gateway to the furthest
sensor in the mesh. To provide the sensor mesh with opportunities to adapt, aim for
an installation where each node has at least 3 other nodes within wireless range.
This sensor radio interface can operate concurrently with other activity in the same
band, including the radios for:
• Wi-Fi, a network/@ptitude Observer connection option
• WPAN IEEE 802.15.1 for app interfacing: on a mobile phone, this is
known as Bluetooth®.
The type of network connection between the gateway and @ptitude Observer
software can be chosen to suit specific site requirements. A hard-wired Ethernet
connection is the default, but Wi-Fi is also provided as a wire free alternative.
Communication between the gateway/sensor and Android mobile app for on-site
sensor and gateway commissioning, is achieved over the phone’s Bluetooth Low
Energy, radio connection.
If the equipment is used in a manner not specified by the manufacturer,
both the safety and functionality of the equipment may be impaired.
Being a Wireless Condition Monitoring System, users must ensure that they
abide by the usage requirements and observe the warnings specified in the
Product Specifications, Certifications, sections for both the sensor and the
gateway.
