Vanguard Wireless Gas Detector

Integrating solutions for smart gas detection and monitoring

Vanguard H2S & Methane Wireless Hart Gas Leak Detector

The ultimate wireless gas detector

Vanguard is a WirelessHART gas detector that can monitor presence of harmful gases for more than five years without a battery replacement. The new Vanguard wireless gas detector reduces monitoring costs and increases safety by eliminating the need for costly and fixed wiring.

Vanguard Wireless Gas Detector
Potential Applications

Once on a wireless network, the Vanguard gas detector can serve many gas monitoring functions, including the following:

  • Wireless remote and local gas detection, such as tank farms, oil and gas production facilities, refineries, pipelines, abandoned wells and waste treatment plants.
  • Temporary situations in which the cost of setting up a wired solution is completely unfeasible, such as a maintenance turnaround, natural disaster, security breach or plant expansion.
  • Asset management initiatives, where trending of emissions over time through the deployment of multiple wireless sensors can initiate the necessary predictive and preventive maintenance, or pollution control monitoring.

The cost of adding just one new gas measurement point, including obtaining ‘hot’ work permits, running conduits for wires, burying them, and so on, can be in the neighborhood of $10,000 for land-based systems and as much as five times that for offshore applications.

Product Highlights
  • Wireless capability
  • Field interchangeable toxic and combustible gas sensors
  • Interoperable with existing WirelessHART networks and asset management systems (AMS)
  • Easy calibration and operation
  • Five+ year battery life*
  • Heavy duty design with Class 1, Div 1 & 2 hazardous location approvals

*Affected by polling frequency


Easy Operation

The Vanguard detector can be mounted anywhere and dropped easily into any WirelessHART network by inputting the network I.D. and join key.

The unit automatically senses the detector type and configures it automatically.

Seamless, plug-and-play interoperability saves additional setup time and effort. Class 1, Div. 1&2 certification and an explosion-proof and intrinsically safe design help ensure trouble-free operation in hazardous environments. The unit also has ATEX and IECEx approvals.

Vanguard gas sensor modules

United Electric Controls developed the Vanguard wireless gas detector in response to the market need for a cost-effective way to add multiple gas measurement points. Vanguard field-interchangeable gas sensor modules detect and record hydrogen sulfide (H2S) or methane (CH4) gas in parts per million (PPM) or percent of lower explosive limits (LELs) respectively, along with network and battery status.

WirelessHART 7.2 technology carries signals to local 128 x 64 pixel digital displays or other IEC 62591 compatible connections — all of which integrate seamlessly with existing supervisory control and data acquisition (SCADA) or asset management (AMS) systems. The Vanguard detector has been designed and tested to interoperate with Emerson Smart Wireless Gateway 1410 and 1420.

Additional Specifications:
  • Operating Temperature: -4°F to 140°F (-20°C to 60°C)
