Wireless Gas Detector with weatherproof enclosure - WGD-100-WP


The Wireless Gas Detectors WGD-100-Series along with the local receiver unit called as Wireless Control Unit WCU-100, are one of the recent technologically upgraded products which work through GSM/GPRS systems and can easily interface with Oxygen, Methane, Combustible & Toxic gas sensors.

They eliminate the use of physical cables that were required for signal transfer between the conventional detectors & multi-channel monitors.

The wireless data communication features integrated within these devices, use the constantly evolving technologies related to the Internet of Things – IoT category.

These devices can be easily operated using a Battery supply or through Solar Panel supply or 24VDC SMPS or 5V, 2A Adapter from AC mains.

Basic Features  & Applications:-

Parameters highlighted by these devices are –

  • Battery percentage,
  • Status of the device,
  • Fault condition,
  • GSM network status,
  • Sensor reading.
  • They are easy to use and work efficiently.
  • Suitable for use in Hazardous Locations.
  • Protection Class- IP-66 for Gas Gr. IIC  & CMRI Approved.

Basically, these devices can be used for all those similar applications where the conventional cabled Gas detector systems were being used. But, extensively, these devices are required in areas where use of cables is inconvenient due to proximity i.e. the detectors and monitoring control units are placed far away or on different floors or where the detectors are placed in confined hazardous areas. Hence, these devices find theirs usage in most of the applications of the following industries.

  • Refineries & Petrochemical plant including offshore drilling and plant shutdowns
  • Bullet yards or Tank farms
  • Steel mills
  • Pulp & Paper Industry
  • Personal Monitoring
  • Gas Pipelines
  • Incoming Cylinder inspection
  • Emergency response
  • Equipment maintenance
  • Pre-entry check quality control 
  • Process or emission gas analysis
