Gas Detectors

United Electric Vanguard - Intrinsically Safe WirelessHART Gas Detector

Overview

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.

It is currently available with either a non-dispersive infrared (NDIR) methane sensor (0-100 %LEL), an electrochemical hydrogen sulphide sensor (0-100 ppm), an electrochemical carbon monoxide sensor (0-500 ppm) or an electrochemical ammonia sensor (0-100ppm).

Wireless gas detectors like the Vanguard can augment existing gas detection coverage with minimal financial and labor outlay. The Vanguard can be plugged-and-played anywhere in an existing WirelessHART® mesh and perform its role as a first line of defence for H2S monitoring.

Features:

  • Wireless capability
  • Field interchangeable toxic and combustible gas sensors
  • Interoperable with existing WirelessHART® networks and asset management systems (AMS)
