The same goes for all owners of process instrumentation. My coffee maker prompted me to reflect on maintenance concepts for both of them one morning recently.<\/p>\n<h2><strong>Maintenance is a must.<\/strong><\/h2>\n<p>No-one would dispute that. It makes no difference whether you\u2019re an owner of a fully automatic coffee maker or process analyzers. Nobody expects a measuring instrument to keep on working for an eternity without a single problem, delivering accurate results without you having to lift a finger. The more complex the analysis system, the truer that is.<\/p>\n<p>There are four questions that particularly concern us in day-to-day practice, especially if we\u2019re faced with an investment decision \u2013 after all, any investment (cost) decision is also a decision about operational costs.<\/p>\n<ul>\n<li><strong>When does it need to be serviced?<\/strong><\/li>\n<li><strong>How often is servicing necessary? How long does servicing take?<\/strong><\/li>\n<li><strong>What needs to be done and how complicated is it?<\/strong><\/li>\n<\/ul>\n<h2><strong>When does it need to be serviced?<\/strong><\/h2>\n<p>One option here might be a regular maintenance schedule. This is generally easy to arrange but it doesn\u2019t always tally with actual servicing needs:<\/p>\n<ul>\n<li>Too late \u2013 the consequences could be fatal<\/li>\n<li>Too soon \u2013 wasted effort, but at least you\u2019re on the safe side<\/li>\n<\/ul>\n<p>My coffee maker only ever starts complaining when I\u2019m desperate for a cup of coffee, in other words when <em>I<\/em> need <em>it<\/em>. At precisely the wrong moment. Before I can quench my thirst, I have to top up the water, empty the dregs and clean the steam nozzle manually. The machine never objects at a time that would suit me (that\u2019s because it\u2019s switched off then).<\/p>\n<p>Ignore it? No good \u2013 the next thing I know it will be telling me I\u2019m risking the warranty. <em>There must be a lesson in that for measuring instrument manufacturers.<\/em> It\u2019s a pity it doesn\u2019t say \u201cOnly ten more cups of cappuccino to go\u201d and then start counting down on a display with big numbers. Predictive maintenance, like you get with our&nbsp; <a href=\"https:\/\/www.yokogawa.com\/solutions\/products-platforms\/process-analyzers\/liquid-analyzers\/smart-digital-sensor\/\">SENCOM system<\/a>, would be just wonderful.<\/p>\n<h2><strong>How often? And how long does it take?<\/strong><\/h2>\n<p>To simply answer \u201cas little as possible\u201d and \u201cas short as possible\u201d would be rather unwise. A few quick manual steps every now and then are perfectly OK:<\/p>\n<ul>\n<li>Top up the water<\/li>\n<li>Empty the dregs<\/li>\n<li>Wipe away the grime<\/li>\n<\/ul>\n<p>It would be even better if some of that could be automated. <em>Ask us \u2013 we\u2019re the automation specialists \ud83d\ude42&nbsp;<\/em> Anything that takes any longer should only be necessary at the longest possible intervals (which reminds me of the steam nozzle again). And talking of \u201clong servicing intervals\u201d, our<a href=\"https:\/\/www.yokogawa.com\/solutions\/products-platforms\/process-analyzers\/liquid-analyzers\/smart-digital-sensor\/all-in-one-digital-smart-ph-orp-sensor-fu24f\/\"> SENCOM FU25F<\/a> digital sensor is a good case in point.<\/p>\n<h2><strong>What needs to be done and how complicated is it?<\/strong><\/h2>\n<p>Question number four, finally, relates to the duration and complexity of the work. With modern devices, knowing \u201cwhat\u201d is not actually the problem any more. We have easy access to<\/p>\n<ul>\n<li>Instructions,<\/li>\n<li>Menu systems,<\/li>\n<li>Manuals that can be downloaded onto a tablet in the field directly from the manufacturer\u2019s website,<\/li>\n<li>etc.<\/li>\n<\/ul>\n<p>Industry 4.0 sends its regards.<\/p>\n<p>It\u2019s the \u201chow\u201d \u2013 all the fiddling around \u2013 that makes the difference. When I forgot to screw the steam nozzle on again properly recently after \u201cmanual cleaning\u201d, I didn\u2019t get any cappuccino out of the machine for a week. Just imagine, for instance, &nbsp;nopolypropylene produced &nbsp;in your plant for a whole week. Sometimes, it really is only the \u201cfiddling\u201d itself that is a nuisance.<\/p>\n<h2><strong>The \u201chow\u201d with zirconia sensors<\/strong><\/h2>\n<p>Zirconia sensors are reliable, low maintenance instruments for measuring oxygen, for example in boilers of power stations. The cell wears out eventually \u2013 somewhen; this depends on the manufacturer. The cell replacement procedure is a good illustration of how \u201ceasy\u201d or \u201cdifficult\u201d servicing and maintenance can be.<\/p>\n<p>By the way, my coffee maker makes excellent coffee \u2013 and that\u2019s what matters most to me! And our zirconia sensors measure very reliably. I wouldn\u2019t give up my coffee maker for the world, but I\u2019m willing to negotiate on the zirconia sensors. <strong>Maybe over a coffee from my fully automatic coffee maker?!<\/strong><\/p>\n<p><strong>Are you looking for answers to these four questions? Are there any other questions you\u2019d like to ask? Feel free to write a comment.<\/strong><\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Maintenance is a must.
