Process visualisation in hazardous areas E
xplosion-proof panel PCs for the onsite control and visualisation of processes make machinery
user-friendly, highly available, and cost effective. This high level of utility is further
enhanced by the POLARIS series because the system also addresses the high security requirements that need to be fulfilled. The eight 12.1-in widescreen touch
panels are used in its present application to control and monitor the filling of wagons in a petrochemical fuelling facility at an oil depot. The new display
technology guarantees the best possible contrast even at wide viewing angle. The Ethernet interface enables individual computers or network devices to be connected to an existing local area network. Safety is of particular importance when using the control and
Wireless handheld thermometer
T
and D Corp announces its new Wireless RTR-601 handheld thermometer and Core
Temperature Recorder. The unit is designed to measure the internal temperature of food items and liquids using an insertion probe. A single press of
the REC button allows the user to record not only the temperature, but also the time, date, operator and item ID’s and a pre-programmed measurement judgment The RTR-601 has a
measurement range of -25°C to 235°C and is suitable for both hot and cold readings. Current readings and Go/NoGo judgment results are displayed on an easy to read, backlit LCD Display. The RTR-601 incorporates a
temperature stabilisation algorithm that will not allow recording until the probe tip

temperature has reached a final, steady state value, and can store up to 1,800 data readings before downloading to a LAN over a 900MHz wireless link. The penetration probes are available in two different lengths and can be attached either directly to the unit or to a handle with a 3 foot cord. The RTR-601 is
designed to be seamlessly integrated into a wireless network with TandD’s RTR-500 Series of Wireless Data Loggers, which allows for automated data collection and remote monitoring and management of both warm and cold. These features makes this unit suitable for HACCP-compliance for
temperature management related to food safety. n

operating system for filling the wagons. The structure was therefore designed to avoid potential dangers posed by the user or the network. For this reason, the BARTEC ZeroClientShell is used as an alternative to Windows Explorer. The functionalities are limited to a
minimum. In addition, the operating system is limited in such a way that data media cannot be used via the USB interface as this will be blocked. However, an intrinsically safe USB mouse
and USB keyboard can be used for service purposes. n

Flexibility with guided wave radar
W
ith its new Sitrans LG series, Siemens Industry is offering a flexible portfolio of guided
wave radar transmitters suitable for virtually any type of industrial application. The modular design of the four basic versions, Sitrans LG240, Sitrans LG250, Sitrans LG260 and Sitrans LG270, allows for level measurement in chemical, food and beverage industries, etc. The modular radar transmitter covers the measurement of liquids and interfaces, from aggressive materials to hygienic conditions and complies with SIL2 safety standard. Sitrans LG’s high frequency
microwave pulses are transmitted down a rod or cable, offering reliable measurement with up to 2mm accuracy in applications with corrosive vapours, steam, foam, surface agitation and/or liquids with high viscosity, low level, and varying dielectric or density. n
