Sontay's Wireless Sensors are Tried, Tested and Time-Savers at Ford
Ford is measuring the ambient relative humidity (RH) within its testing bays, at the Dunton Technical Centre in Dunton, Essex, with Sontay’s ground-breaking SonNet wireless sensor system.
Technical Centre is one of Europe’s largest automotive R&D centres
and employs around 3,000 people. Engineers at the facility regularly
conduct emission tests and, so they can reach optimum efficiency when
running the vehicle, the relative humidity of the testing bays needs to
be measured. When testing vehicles, Ford needs to ensure the ambient RH
is measured and controlled by the Building Management System (BMS) so
it does not interfere with its own tests. If required ambient RH
figures are not met the tests can be deemed to fail, so it is extremely
important for Ford to have a sensor system that is reliable and
In this constantly
changing environment, it was vital for Ford to be able to install
sensors that could be quickly and easily moved and re-positioned as
necessary so wireless was the perfect solution.
Part of the testing process often includes moving equipment that generates heat around the vehicles under test, meaning it can be hard to monitor the ambient RH of the bays. Therefore, sensors are required to be moved around to ensure the ambient RH readings are accurate. As wired sensors are difficult to re-locate quickly, the SonNet wireless system was the obvious choice for building controls specialists, Schneider Electric.
Following a detailed site survey, fully supported by Sontay’s field representative, Schneider Electric were able to prove that the equipment would work correctly prior to installation and installed three sensors within the testing bays.
“The survey was very comprehensive” comments Peter Wright, Support Engineer at Schneider Electric and based at the Ford Dunton Technical Centre. “The representative from Sontay had a good knowledge of the equipment and gave good advice about how to site the equipment. The installation was simple and connection to the local BMS system was hassle free.”
Since sensor operation is based on the latest 2.4 GHz licence free radio technology, specifying SonNet sensors eliminated the need for Schneider Electric to run any structured cabling to the products, making it a quick and easy process.
SonNet radio receiver converts transmitted data from the sensors to
analogue outputs (compatible with most control systems). The receiver
is available with 20 channels, as standard, and up to 40, with the
addition of an optional 20 way Daughter Board. Due to the nature of the
site, having a secure wireless system was of paramount importance.
Sontay was able to reassure Ford that the SonNet system is extremely
secure and the sensors run a self-healing tree application for maximum
reliability, operation and battery life. This ensures robust ‘fit and
forget’ communications with lower installed project costs. The sensors
themselves feature a battery lifetime of up to five years and are
available in a number of variants, catering for space, immersion, duct
and outside air monitoring.
“Sontay had a complete system which suited our needs and I knew it
would be compatible with the building management system onsite. With
the software the company provides, the system is extremely easy to
install and commission. I like the feature on the Base Station that
allows you to monitor the battery life of the wireless sensors and each
one can be renamed to suit our requirements, which is really helpful”.
Sontay products and
control solutions are designed to help improve building management
system performance reduce energy and maintenance costs and increase
occupant comfort levels. For further information on the Sontay
