intrinsically safe certification, alongside ATEX certification, for their range of Senturion X DNX803 series of transmitters. These upgraded shaft vibration and axial position transmitters are approved for installation and use in hazardous areas with potentially explosive atmospheres (gases) or dusts. The DNX8031 (shaft

process means they dispense the right amount of epoxy, in the same place, every time - achieving the highest levels of quality. “A key selling point of our gas sensors is
that they will not leak during their lifetime,” comments Rob White, sales director at DD- Scientific. “We take pride in supplying our customers with the absolute best equipment, to support them with their life-saving technology, be it an oxygen sensor on an incubator for a new-born baby or a carbon monoxide sensor in someone’s home. “With a throughput of 1.5 million sensors a
year, all with a minimum of two pins to seal, the time saved by removing the manual processes equates to 23 days a year,” added White. “We have been able to move the five people involved in the manual process into more valuable areas of the business and can now produce a potentially life-saving gas sensor every seven seconds.” “There is a real buzz in the air at DD-
Scientific,” says Matt Baseley, technical sales executive at Intertronics. “The team is clearly committed to being the best in their field. Equipped with an automated, volumetric dispensing process, DD-Scientific can maintain its clear competitive advantage and increase its throughput, all while making time and resource savings. We love that they have called our system ‘Barbara’, and made a movie about her! I’m excited to see what the company does next.”

vibration) and DNX8033 (shaft position) proximity probe transmitters are suitable for above ground applications when used in conjunction with Sensonics intrinsically safe range of XPR eddy current type proximity probes and XEC cables. These 4-20mA loop
powered modules provide easy integration with either the local machine PLC or a plant wide DCS since it is powered through the safety barrier measurement loop. All signal processing is carried out within the unit providing an output current proportional to either peak-to-peak shaft vibration or relative position to the probe face. The module permits the adjustment of both gain and offset for ease of calibration to suit the application. Smaller pumps, centrifugal air compressors,
motors and fans will particularly benefit from the upgraded DNX803 series. When combined with Sensonics range of compact machine mounted housings, the upgraded transmitters provide a very cost-effective solution for critical operational measurements, with the benefits of a straightforward interface that requires no local power supply. The transmitter offers selectable system
lengths of 5m, 7m or 9m, with a front panel green LED for indicating the selected option. A gap voltage monitoring socket is also provided. The cable system incorporates snap
achine protection and condition monitoring specialists SENSONICS has added IECEx and UKEx
lock connectors which require no torqueing and provide a shake-proof solution which is important for heavy industrial applications. The double screened cable offers
robustness combined with high immunity to interference while the option of stainless steel convoluted armour is available for applications and environments where cable protection is paramount. Ideal for many OEM applications, the
transmitter also provides a raw buffered output of the vibration signal that can be utilised through portable analysis equipment for a more detailed picture of the dynamic performance of the machine.
