ROUND UP
Enviro management and control
Fluke and HART Scientific have revolutionised environmental monitoring for calibration labs
with their model 1620A DewK which offers Ethernet and wireless connections and upgraded
LogWare III software.The DewK has inputs for two sensors, each measuring both temperature
and relative humidity, so that the DewK can monitor two locations simultaneously. Both sen-
sors can be run via extension cables to remote locations up to 100 feet away, or one sensor
can be directly mounted to the top of the DewK.
Two types of sensors are available from Hart.The high-accuracy sensor (‘H’ model) reads
temperature to ± 0,125°C over a calibrated range of 16°C to 24°C. Relative humidity readings
are to ± 1,5%RH from 20%RH to 70%RH.The standard-accuracy sensor (‘S’ model) reads tem-
perature to ± 0,25°C over its calibrated range of 15°C to 35°C. Relative humidity readings are
to ±2%RH from 20%RH to 70%RH. All DewK sensors come with NVLAP accredited certificates
of calibration for both temperature and humidity, complete with data and NIST traceability.
The DewK features built-in Ethernet RJ45
jack and multiple DewKs can be monitored
from the same screen using the new LogWare
III client-server software. Ethernet also allows
for the possibility for remote connectivity over
the internet, so that critical conditions can be
monitored from a remote location and data can
be sent to a printer through the RS-232 interface
in real time.

CABLES + ACCESSORIES
High-performance cable festoon systems
Powermite, part of the Hudaco Group, supplies superior quality high-performance cable festoon
systems for the efficient feeding of power, data, air, or fluids to keep mobile bulk materials
handling and mining machinery moving. Since establishing a partnership with French multi-
national, Delachaux, and its Conductix-Wampfler operation, Powermite’s materials handling
division has been distributing Conductix products including Cable Reeling Drums(CRDs),
slip-ring housings and festoon systems to the Southern African mining and industry for over
40 years. Open cast and underground mining operations, stockyards, ports and other bulk
handling facilities rely on powerful electric machines to do the heavy work. Maximum uptime,
fundamental to high production levels, relies on reliable, easy to maintain materials handling
machines. “It is therefore essential to install high quality specialised festoon systems to ensure
uninterrupted and reliable feeding of energy, data, etc. to these machines even in extremely
harsh and arduous environments,” states Powermite Marketing Director, Donovan Marks.
The cable carriers used on the Festoon systems are custom made, compact, rugged and
reliable in order to protect and manage flat and round power/data cables for electrical en-
ergy and data transfer to machinery. These low maintenance feeding systems contribute to
maximised uptime and productivity due to easy installation and uncomplicated operation.
Available in an array of configurations, these feeding systems are ideally suited for use on
virtually any type of moving equipment, such as bulk material conveyors, stackers, reclaimers
(including circular), travelling hoppers, rail car dumpers, plating lines, water treatment and car
wash systems that operate in industries such as mines, steel mills, ports (container handling
and ship-to-shore power supply), power plants, airports, warehouses, automotive facilities,
etc. Irrespective of the particular cable or hose package, the running speed or location of the
machine (indoors or out), Powermite/Conductix-Wampfler has the appropriate ISO 9001:2008
certified system to keep plants, mine sites, cranes and ports moving. Incorporation of the latest
modern technology into the modular design ensures an above-average operational life of the
cable festoon systems, even in the harshest of environments.
