As the illustrious moderator has pointed out, what you have asked and what you have provided to us reduces the chances of getting what you want. I have interacted with some pretty bright, knowledgeable individuals on this site. They will share their knowledge and experience to solve a problem. It is not free. It requires an investment. I invest by providing as much information that i have. What I know. What i don’t know. I hope that the investment increases my chances of getting a response. I don’t guarantee the formula works, but if experience is the measurement, I have had more success than failures.https://community.element14.com/technologies/experts/f/forum/57149/mmm-multifrequency-modulated-and-multi-wave-ultrasonic-technology/237825Thu, 13 Aug 2026 05:39:00 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:9745f296-1387-4d07-b21b-c161f7f66002Rick1234Abandoning the originally pic'd "clamp-on" type transducers! That method requires too much ultrasonic energy that way. Submerging the transducers into the "nucleation chamber" (pipe!) with a direct water contact requires a much lower power demand. I now don't believe I require the complexity of an MMM ultrasonic paradigm for this "water treatment" setup ..... as the water's path to be treated flows tightly "captive" to the confines of the nucleation chamber affording a uniform nucleation of the minerals passing thru. My thoughts are to alternately fire the ultrasonic transducers for a uniform nucleation of the water ...... but, without "imploding"!https://community.element14.com/technologies/experts/f/forum/57149/mmm-multifrequency-modulated-and-multi-wave-ultrasonic-technology/237816Wed, 12 Aug 2026 04:18:00 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:b5066fd3-a7f9-46d2-9870-f8f507ad5182Rick1234I had assumed "cavitation" was always accompanied by an ending implosion ! : ( With ultrasonics you can have both "stable" and "inertial" cavitation under your control! For use in my ultrasonic "nucleation" of the scaling minerals, only a stable cavitation is required and has a significantly low power demand.https://community.element14.com/technologies/experts/f/forum/57006/bosch-plena-lbb1935-schematic/237791Mon, 10 Aug 2026 10:23:00 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:aeb01105-53ae-469b-97a4-cc28d90fa01ecstantonLikely proprietary.

Better lab testing should reveal such things before they happen. whether the component is in spec for the environmental conditions, will be defined in the datasheet. I test failure patterns on all the hardware we use, regardless of spec. To do that, some of the tools I use are small ovens, thermal cameras, oscilloscopes, function generators, and insulated boxes of various sizes. Everything will fail. You should know the conditions where the products you use fail. Maybe its heat. maybe its noise from some other device, maybe high ambient humidity does it. when your techs show up, after whatever unit fails, do the components seem to work? or is there permanent damage? Is there discoloration? smells? surface texture changes? I had these relays operate at max load for 24 hours per their rating. The plastic got kinda soft. thats a fail. Others caught fire. testing the spec isnt even abuse. Ill abuse the crap out of a device to make sure it works as expected every time. we had one last year when some panels installed on a roof in the sun reached 130+ degrees. nice, we didn't anticipate that. we fixed it by installing a little roof to cast some shade. Thats a hack. I wouldn't point to that install as a proud moment in controls engineering. I cant say to a customer, hey we normally install these in mechanical rooms, or basements, this whole roof top thing, .. we didn't test for that.https://community.element14.com/technologies/experts/f/forum/57156/question-industrial-optocouplers-keep-failing-on-site-what-thermal-management-products-can-solve-this-issue/237733Thu, 06 Aug 2026 14:03:00 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:4d3c4dee-240a-4fa9-83ba-506d5191bed9dougwIf the ambient temperature is too hot, you may not have anywhere to transport the heat.

Are other types of coupling elements suitable for your industrial application instead of optocouplers? If so, try replacing them, ideally with a 1:1 pin-compatible interface. ...Well, only optocouplers allow for static coupling, e.g., direct on/off; the others are dynamic couplers, capacitive/inductive, or especially wireless, which makes things complex and expensive. So, choose a sensible approach. Cooling also adds to the cost.https://community.element14.com/technologies/experts/f/forum/57156/question-industrial-optocouplers-keep-failing-on-site-what-thermal-management-products-can-solve-this-issue/237727Thu, 06 Aug 2026 08:23:00 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:45db0fb1-f681-48c5-ab10-b82a85e7fc90michaelkellettNot enough information here to offer any advice.

Besides standard cooling fans, I’m wondering what mature thermal management products, thermal conductive components or circuit design solutions are available to reduce high-temperature damage. It would be much appreciated if anyone could share solutions that have been applied in industrial or automotive projects.automotive electronicsthermal managementoptocouplerindustrial automationhttps://community.element14.com/technologies/experts/f/forum/57149/mmm-multifrequency-modulated-and-multi-wave-ultrasonic-technology/237724Wed, 05 Aug 2026 22:05:00 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:4f7daaf4-b399-4993-b891-d3fea368c6d5Rick1234Agreed! ....... well said! : ) Well , I can't just go and buy their OEM unit ...... as even the smallest version is $25,000.00 !! : ( But, I did download their MMM control software! : ) This affords many "clues" as to what's going on behind the scenes as to the manipulation of the ultrasound to its MMM script. I see the obvious set high/low range parameters for the ADSP ...... no problem! The hard part will be scripting the scanning matrix of all the variables (ie: power, frequency, PWM, phase, etc) to emulate the attributes of MMM. My first thoughts are: the nature of such a script would require the extensive use of a Kalman filter.https://community.element14.com/technologies/experts/f/forum/57149/mmm-multifrequency-modulated-and-multi-wave-ultrasonic-technology/237719Wed, 05 Aug 2026 09:03:00 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:f8bb02cd-6314-40a2-95f3-17ce3bc06cb2michaelkellettNow I see where you are coming from ! The MPI people look serious and real - they have patents and build 100 KW+ systems . I suspect that the best way to get their technology is to buy some stuff from them. To replicate it (commercially) you would need to understand the patent situation and be sure you were not infringing. As far as generating the signals goes then it rather depends on you skills and resources. I don't know enough about MPI's signal processing to make an actual recommendation but somethign like this might do: https://www.analog.com/en/resources/evaluation-hardware-and-software/evaluation-boards-kits/sharc-audio-module.html#eb-overview To use it you need a good understanding of DSP and C programming. Probably access to a tool like MATLAB for signal processing development work. The ultrasonic driver board - if you are feeling bold then look on Ali Baba and Aliexpress - but if you are at "day one with ultrasonics" be prepared to get your fingers burned - once when you buy it and then again when you try and use it. I think you might need to hire someone with experience of high power ultrasonics. But if you want to sell a system to end users like you applications suggest why not plan to buy in the parts from a source like MPI - then you'll have an expert on your side rather than competing. The investment to compete with them on developing making the core ultrasonic components would be large. But developing a system like you washer dryer is bridging a gap between companies like MPI and people who want to wash and dry stuff - there may be a gap there you can fill. Please note: the above free advice should be treated with the usual caution - I know very little about the context of your project.

An attribute of ultrasound cavitation in water is its ability to kill viruses, germs, bio films, including Sars-CoV-2 and influenzas-A Drying of the clothes would start with high speed water vacuum extraction and final drying done under sub-atmospheric pressure (ie: boil off the remaining dampness with no applied heat ).https://community.element14.com/technologies/experts/f/forum/57149/mmm-multifrequency-modulated-and-multi-wave-ultrasonic-technology/237701Tue, 04 Aug 2026 16:33:00 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:37ac8f2a-97f0-4391-bd77-fcf77a2f5fe6cstanton[quote userid="121623" url="~/challenges-projects/design-challenges/f/forum/57149/mmm-multifrequency-modulated-and-multi-wave-ultrasonic-technology/237693"] I can't persuade the E14 editor to put the picture above in context after Rick124's request re. the microns and metres.

" - MK The weak aspect of TAC and NAC is that the chlorine in city water degrades these polymer resins ..... shorting their life span in halve! Its common practice to install a carbon granular tank ahead of the TAC/NAC treatment tanks to negate this issue. Even then, the normal lifespan of these expensive resins is only 3 to 5 years and has to be replaced. Using an ultrasonic solution ( no polymer resins ) to provide the nucleation of the scale components ..... essentially is maintenance free!https://community.element14.com/technologies/experts/f/forum/57149/mmm-multifrequency-modulated-and-multi-wave-ultrasonic-technology/237699Tue, 04 Aug 2026 16:01:00 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:0cc55f78-42a3-4ccd-90ef-234bee7617bbRick1234community.element14.com/.../5415.mmm_5F00_basics_5F00_presentation-_2800_1_2900_.pdf
