Fluke Precision Infrared Thermometers

Fluke Precision Infrared Thermometers Offer a Broad temperature range, superior optics and the advanced extra-bright three-dot laser sighting system make Fluke 570 series thermometers the most advanced portable thermometers in the industry.

The Fluke 570 non-contact thermometers are ideal professional diagnostic tools for maintenance professionals requiring the most accurate temperature readings at all distances. The Fluke 570 series infrared (IR) measures surface temperatures, helping to quickly locate lubrication problems, overloads, short-circuits or misaligned and overheated equipment, reducing work and follow-up time, and improving performance. From close-up electrical connections, to distant room balancing checks, the Fluke 570 series can take IR temperature measurements with ease. Predictive maintenance professionals requiring analysis and documentation use the 574 model with 100-point data logging and included software for graphing and analysis for follow-up reporting and documentation.

The Fluke 574-NI Nonincendive Model
When safety is a concern and data logging and downloading are required, the Fluke 574 Nonincendive (NI) model thermometer is the product to choose. It has the same great features as the standard 574 model thermometers with the extra confidence of a Factory Mutual approval for use in hazardous environments*. *See specification table for details. The Fluke 574-NI thermometer, does not release enough electrical or thermal energy to ignite flammable gases or vapors under normal operational and environmental conditions.

Accurate measurements depend in part on accurately sighting a target. Fluke 570 series thermometers are the only thermometers with a sighting system designed to precisely track the infrared path as seen by the sensors. This enables the advanced coaxial three-dot laser sighting to accurately show both the center and the edges of the spot being measured, regardless of the thermometer’s distance from the target. This laser sighting also appears twice as bright to the human eye as normal lasers (while maintaining the same safety rating as less bright lasers), making precise sighting easier in a variety of lighting conditions and distances.

What is IPTV?

Since its inception in 1994 many different definitions of IPTV have appeared, including elementary streams over IP networks, transport streams over IP networks and a number of proprietary systems. The official definition approved by the International Telecommunication Union focus group on IPTV (ITU-T FG IPTV) is as follows:

“IPTV is defined as multimedia services such as television/video/audio/text/graphics/data delivered over IP based networks managed to provide the required level of quality of service and experience, security, interactivity and reliability.”

Another official and more detailed definition of IPTV is the one given by Alliance for Telecommunications Industry Solutions (ATIS) IPTV Exploratory Group on 2005:

“IPTV is defined as the secure and reliable delivery to subscribers of entertainment video and related services. These services may include, for example, Live TV, Video On Demand (VOD) and Interactive TV (iTV). These services are delivered across an access agnostic, packet switched network that employs the IP protocol to transport the audio, video and control signals. In contrast to video over the public Internet, with IPTV deployments, network security and performance are tightly managed to ensure a superior entertainment experience, resulting in a compelling business environment for content providers, advertisers and customers alike.”

One definition for consumer IPTV is for single or multiple program transport streams (MPTS) which are sourced by the same network operator that owns or directly controls the “last mile” to the consumer’s premises. This control over delivery enables a guaranteed quality of service (QoS), and also allows the service provider to offer an enhanced user experience such as better program guide, interactive services etc. In commercial environments IPTV is widely deployed for distribution of live TV, video playout channels and Video on Demand (VOD) material across LAN or WAN IP network infrastructures, with a controlled QoS. In 1994, ABC’s World News Now was the first television show to be broadcast over the Internet, using the CU-SeeMe videoconferencing software. The number of global IPTV subscribers is expected to grow from 28 million in 2009 to 83 million in 2013. Europe and Asia are the leading territories in terms of the over-all number of subscriber. But in terms of service revenues, Europe and North America generate a larger share of global revenue, due to very low average revenue per user (ARPU) in China and India, the fastest growing (and ultimately, the biggest markets) in Asia. The global IPTV market revenues are forecasted to grow from US$12 billion in 2009 to US$38 billion in 2013

LOFAR started as a new and innovative effort to force a breakthrough in sensitivity for astronomical observations at radio-frequencies below 250 MHz. The LOw Frequency ARray is a multi-purpose sensor array. Its main application is astronomy at low frequencies (10-250 MHz) but also has geophysical and agricultural applications. Its heart is currently being assembled in the Northeast of the Netherlands and spreads over the whole country and over whole Europe.

LOFAR uses a large number of low-cost sensors (antennas, geophones and more) and relies on broad-band datalinks and advanced digital signal processing to implement the majority of its functionality in (embedded) software.

LOFAR will be the first large radio telescope system, wherein a huge amount of small sensors are used to achieve its sensitivity instead of a small number of big dishes.

The main reasons for this are:

• For the low frequencies involved in LOFAR traditional telescopes would be very large and hence costly.
• Pointing can be done electronically, without using move-able parts and hence saving on maintenance costs.
• It enables pointing in multiple directions at the same time.
• It provides operational flexibility (e.g. rapid switching between observations is possible).

From the LOFAR Site:
Her Majesty the Queen will open the largest radio telescope in the world, LOFAR, on Saturday afternoon 12 June 2010 in Borger-Odoorn (Drenthe). The new LOFAR telescope has been built according to a completely new concept. No large dishes are used, but large numbers of small antennas.

7,000 antennas are spread over 44 fields in the North of the Netherlands and from Sweden to France and from the UK to the East of Germany. Glass fibres connect the antennas with a supercomputer at the University of Groningen’s Computer Centre. In this way, a giant telescope is formed with a diameter of one hundred to one thousand kilometres.

The telescope researches, among other things, the earliest Universe, cosmic particles and magnetism in the Milky Way and other galaxies. LOFAR is also used for research in the area of geophysics, precision agriculture and ICT. While the antennas observe the sky, underground sensors collect date about the structure of the Earth. These data contribute to better models for the Earth, water management and gas exploitation. (source www.lofar.org)
