United Electric Vanguard Intrinsically Safe WirelessHART Gas Detector

The Vanguard Toxic and Combustible WirelessHART® Gas Detector was born to be wireless. With a 5-year battery and 1-button calibration — the Vanguard is a gas detector built for the wireless world! The new Vanguard WirelessHART gas detector’s flexible monitoring of toxic or combustible gas can save lives. Its ultra-long battery life saves maintenance trips. Its easy pushbutton calibration; mount-anywhere mobility; and seamless, plug-and-play interoperability save time and trouble. And of course, eliminating long wiring runs saves thousands in installation costs.

The Vanguard WirelessHART® gas detector is ideal for the monitoring of toxic and combustible gases without the need for costly and fixed wiring. With a five year battery life and one button calibration, the Vanguard detector is easy to operate and maintain. Each Vanguard detector has a WirelessHART® transceiver, an antenna, a display, a long life power module, a gas sensor, and a signal processor for the gas sensor. Vanguard uses a sensor architecture trademarked “Flexsense,” which allows the sensor to identify its target gas and self-configure to a Vanguard transmitter upon connection.
