SAT120 Wireless Gateway Solution


Wireless Sensors are an alternative to hard wiring due to:

  • Impracticality of Hardwire Installations
  • High Cost of Wiring/Conduit Installations
  • Portability Requirement

The SAT120 Wireless Gateway Solution

The SAT120 Wireless Gateway provides simple yet powerful Wireless Monitoring, Alarm Callout & Data Acquisition.  The SCADALink SAT120 integrates with the the SignalFire Wireless Sensor Network to provide an compact low power integrated wireless sensing solution.  Each SAT120 Wireless Gateway equipped with  SignalFire Wireless Gateway can connect to up to 240 Sentinel Wireless Sensor nodes.  With low power operation, the SAT120 wireless Gateway can be solar powered.

Wireless Sensors Communicating to Wireless Gateway

Wireless sensor nodes can communicate to Wireless Gateway and ranges up to 1/4 mile range eliminating troublesome hard wire connections. Even cable runs of50 feet may be difficult due to trenching requirements.

Wireless Sensor Clusters Communicating to Wireless Gateway

Where additional sensors are required and are within the range of the Wireless Gateway (up to 1/4 mile),  additonal cluster  of sensors nodes can be installed and communicate to the Wireless Gateway directly.  In this case only wireless sensors need to installed for the additional site to be monitored.

Wireless Sensors Communicating via Repeater

Where Wireless Sensors are out of range of the Wireless Gateway,  a Wireless Repeater can be installed to extend the range.  The range of the Wireless Gateway to Repeater can be up to 3 miles.

Wireless Flexibility

With the Wireless Range of the SignalFire Network of 1/4 to  3 mile , a single SAT120 Wireless Gateway can be used to monitor  multiple field sites by adding an additional wireless sensors nodes.  Alternatively in areas with challenging terrain, the SAT120 Gateway can be installed at location with optimum cellular/satellite communication  while the sensor nodes placed at the measurement points. For applications that are temporary such as well testing or offset well monitoring, wireless nodes eliminate safety concerns from loose cabling, and from hazardous area wiring requirements.
