Test & measurement The height gauge features a pair of lateral

insert holders, a testament to the research and development of generations of instruments that have forged Trimos’ reputation. Their great robustness and flexibility allow the use of very diverse probes up to 400 mm long with impressive repeatability. Chelburn Precision also invested in the

squareness electrical probe which enables the business to reach the full height of components, both for measuring positions and measuring squareness. The additional probe creates the efficiency of combining two instruments to make the measurement process quicker and easier, offering the team the ability to perform the precise measurements they needed. Chelburn’s dedicated inspection department

is manned full-time by two qualified inspectors who have access to a wide range of quality equipment. Because they can trust the readings given by the V7, the team know instantly if there is something that needs altering on the shop floor, allowing them to measure parts easily and quickly and get results before they reach the CMM. Since having the Trimos V7 height gauge,

Chelburn has found the height gauge extremely easy to use, with inspectors using it in preference to traditional methods of parts inspection, owing to the fact they can measure multiple sizes with the one device. Now using the Trimos V7 every day, the inspectors also use the height gauge on smaller manufactured parts, as they find it easier to use and more reliable than their previous unit. Michael Horsfall, production director at

Chelburn Precision said, “We have used Bowers Group before for a lot of different measuring devices we own, so we knew we were in good hands. They even loaned us a smaller unit for us to trial as they were confident that we would be impressed by the quality, accuracy and ease of use of the Trimos height gauge.”

eather and research stations or sites for the extraction of raw materials are often

located in very remote regions of the world. When a local power supply is required in such situations, the only long-term option is a generator. Generators are operated with diesel oil,

which often must be transported over hundreds of kilometres. A generator operates under varying loads, which results in varying consumption volumes. For this reason, tank volumes cannot simply be divided by the number of days but rather have to be measured regularly. The technology used for this is

subject to very exacting requirements because the hot temperatures and the burden of environmental factors such as sandstorms, for example, place high demands on the instruments. KELLER installs the 26 Y Ei level probe level probe for a variety of fuel suppliers and pump operators. This level transmitter excels with extremely high levels of accuracy , excellent long-term stability and no pressure hysteresis . The integrated overvoltage and reverse polarity protection together with the compact, tough stainless steel casing round out the ideal profile.

But above all, low rates of failure are of the highest importance for these extreme sites and these can be guaranteed by the manufacturer with Swiss Made quality, capitalising on all the advantages of automated, wireless monitoring. This is because, in order to guarantee

the necessary supply, the amount of diesel oil required, and when, must be determined at the supply point on an ongoing basis. In such remote areas, this task can hardly be carried out through manual data readings. For the fill level measurement, the level

sensor is mounted inside the diesel tank, at the top, and transfers the data to a Cloud with a remote transmitter via GSM, LoRa or Sigfox. The transferred data is then processed by a software programme specifically for the client and equipped with the chosen alarm functions. The customer then uses the software to install IoT processes such as automated supply deliveries or invoicing. KELLER’s 26 YEi level probe is now being

used in thousands of diesel generators in the deserts of the Middle East. Since 2011, over 8,500 probes have been installed by just one customer alone.
