Wireless Monitoring Applications: Gas Detection
FEDD can employ any number of methods utilizing our unique devices to monitor gas emissions data
and transmit it wirelessly across the facility, and beyond. FEDD offers the total wireless solution
for capturing, transmitting and integrating gas emissions data economically, across the plant, across
the road, or across the continent. The performance, reliability, integrity and service life of
FEDD devices in the some of the most rigorous and congested environments has been proven to be unequaled.
FEDD Gas Emissions Sensing and Monitoring Devices
FEDD single point gas emissions sensing and monitoring devices provide reliable and economical gas emissions
data acquisition and transmission in a single self-contained, self-powered unit. In areas where AC power is
limited or unavailable, the use of FEDD single point gas emissions sensing, monitoring and transmitting devices
allows economical acquisition and timely utilization of important physical property data. These patented devices,
available for many environments both atmospheric and submersible with operating ranges as defined by the specific
application (LEL, ppm, ppb) are self-powered or can be connected to existing loop power if available (DC or AC).
Gases monitored include but are not limited to VOCs, CO, CO2, H2S, and O2. The FEDD gas emissions monitoring system
can operate independently or in conjunction with our wireless data acquisition system and is capable of monitoring
independent emission points. The system can be programmed to transmit data to the control room for alarming at
predefined levels and/or to activate an alarm. The single point device has a self-transmitting range of ¾ miles. For
longer transmission distance requirements, the use of FEDD intelligent repeaters expands the effective transmission
range to 7 miles plus. For off-site transmission of critical data, the use of other methods can be incorporated into
the data integration system.
Other Gas Emissions Monitoring Devices
Where loop powered gas emissions and emissions monitoring instruments are already in use and the output data is required
at remote locations, the use of FEDD single point wireless transmitters brings the signal to the control room or wherever
desired, without costly hard-wiring. FEDD can integrate data from other gas emissions sensing and monitoring devices
outputting analog (4/20 mA) or digital signals and transmit this data wirelessly using our single point transmitters
powered by battery or the existing loop. These devices have a range of ¾ mile which can be increased to 7 miles plus using
FEDD intelligent repeaters.
Multiple Gas Emissions Monitoring Devices – By Others
In the instance where data from single or multiple devices monitoring gas emissions is required at remote locations, the use
of FEDD Remote Transmitting Units (RTUs) receiving either analog (4/20 mA), digital signals or other types of protocols (such as Modbus) from the devices and transmitting
wirelessly to the control room and/or other remote locations is the optimal solution, economically and operationally. Where
loop power is not available, FEDD RTUs, solar powered with battery backup, can provide continuous power to any instrument designed
to be loop powered. The RTU can also be equipped with an independent alarm for reading a set of dry contacts. Utilizing FEDD RTUs,
system expandability is virtually unlimited. FEDD RTUs are unique in the industry, allow for virtually unlimited flexibility in the
system, are unequalled in performance and reliability and are among the most important technical advances in wireless data acquisition,
transmission and integration to date.
