Products Editor’s Choice Space saving in Fast location of buried pipes and cables hazardous areas
To connect inductive proximity switches for hazardous areas, EGE provides the IKM 122 Ex- 230 amplifier that conforms with the current standards according to ATEX Directive 94/9/EG. The device, at 22mm wide, is suitable for space saving installation on DIN-rails. It is designed for use with EGE’s intrin- sically safe two wire sensors for explosive gas and dust atmospheres. The amplifier’s functions include integrated cable break detection and
short circuit monitoring LEDs on the amplifier’s front side which indicate the operating status and alarm messages. Users can choose between a relay and a changeover contact switching output. EGE

Saving power and money
Brunel Industries has launched a new joint venture called Genesis power tech- nologies to deliver power saving tech- nology to help UK businesses to make savings on their electricity bills and reduce their carbon footprint. Brunel’s Power Saving Systems (PSS)
are electronic devices that plug straight into an organisation’s 3-phase electrical system to reduce power usage. Typically the PSS has produced results in excess of a 30% reduction in electrical con- sumption, reducing the amount of power taken from the grid and improving the efficiency of the existing systems. Alan Bailey of Brunel Industries, said, “With rising energy bills and the potential for a nation wide energy shortage a stark reality, it is essential that businesses look to improve their energy efficiency to cut costs and be prepared for the future.” Brunel Industries

Megger has launched its new SebaKMT EasyLoc line location sys- tem that enables the route and depth of buried cables and pipes to be determined quickly and accurately. The EasyLoc system offers a choice of operating modes, making it suitable for use with ener- gised or dead power cables, along with metallic pipes. The EasyLoc system has two main components - a transmitter and a handheld receiver. When tracing energised cables, the receiver is used on its own and looks for power frequency sig- nals radiated by the cable. The user simply scans the likely route of the cable with the receiver until a clear signal is indicated, and then by positioning the receiver at the point of highest signal strength, the cable location is indicated. For convenience, the signal strength is indicated audibly via the built-in loudspeaker as well as visibly by the instrument’s large backlit display panel. Once the location of the cable has been determined, its depth can be measured and displayed by simply pressing a button on the receiver. The procedure for tracing pipes and unenergised cables is very similar, but in this instance the transmitter is used to inject a unique test signal into the pipe or cable. This can be done by direct connection of the transmitter, or by using induction to couple the test signal. As the transmitter has a mains voltage proof output, it can also be used with energised cables to pro- vide improved accuracy in difficult operating conditions. The SebaKMT EasyLoc system supports operation at 33kHz, which means that it is compatible with other location systems, and for ease of operation an automatic sensitivity control is built- in. As a further benefit, the instrument has a self calibration
check routine that will save on maintenance costs. Optional accessories of the EasyLoc system include a pipeline transmitter for locating non-metallic pipes, a transmitter clamp for coupling the transmitter signal into energised cables without the need for direct connections, a house connection set for con- necting the transmitter signal via a standard socket outlet, and headphones to enable the receiver’s audible output to be moni- tored in noisy environments.

Enter 229 Extension of sensor range
Siemens Industry has extended its range of temperature sensors to include the SITRANS TS product family which is suitable for a range of applications. The new resistance thermometers and ther- mocouples are designed for universal
use. The device line has a modular design, and offers a large range of sizes, materials, sensors and transmitters. It not only supports the central communication standards HART, PROFIBUS PA and Foundation Fieldbus, but is also certified under ATEX and IECEx, enabling the devices to be used worldwide. SITRANS TS is suitable for both basic and demanding applications throughout the entire process industry.
The product range consists of three product lines - SITRANS TS100, TS200 and TS500 - which are suitable for applications in chemicals, oil, gas and power. Certain designs are certified under ATEX and IECEx as being flame-proof for gas and dust, intrinsically safe, and Ex n. The SITRANS TS100 and TS200 product series are available as cable and compact thermometers, making them well suited for univer- sal use, such as detecting the temperatures of machine bearings. The compact insertion thermometers can also be used in confined spaces, and their mineral insulated design makes them not only flexible, but also resistant to vibrations and high temperatures up to 1,100°C. The SITRANS TS500 product line is designed for applications with low to high process stresses. A selection of protective tubes made of solid or welded pipe material is available for this purpose. The user can use a wide range of process connections, connection heads, sensor types, transmitters and displays to configure individ- ual solutions for a process. Siemens Industry

High density connection
The new HARTING Han(R) Q High Density is a rectangular connector for signal contacts which delivers the high- est contact density in the company’s compact Han(R) 3A size range. It incor- porates 21 D-Sub contacts, including one designed as a leading contact. The connector addresses the chal- lenges presented by harsh ambient con- ditions where ease of handling is needed in addition to the connector being dust- proof, dirt-proof and waterproof. In partic- ular, it can be used in environments in which gloves are worn.
The extensive range of housing types comprises metal and plastic, EMC and stainless steel.
The connector operates in the safety extra low voltage field at 50V AC and 120V DC. The current load capacity depends on the contacts and cables employed - for turned D-Sub contacts for a conductor cross-section of 0.56mm, the current load capacity at 40C is approximately 6.5A. HARTING
