In the semiconductor industry we use pressure and vacuum switches. On the inductive dry etch modules I work on the pressure switches are used to communicate to us when our low vacuum reaction chambers are at atmosperic pressure, thus safe to open for maintenance. We use manometers to measure vacuum for pressure control during our processes. I was just introduced to this channel and will be recommending your content to our technicians. Thank you.
An excellent basic explanation of how pressure switches work. I'm currently dealing with a 2020 Freightliner Cascadia semi truck. It has a Honeywell pressure switch that notoriously goes bad on these trucks and it's hard to find and very expensive. The truck has a 130 PSI system. When the pressure drops below 80 lbs it sends a signal to the system. I figured it had some kind of a diaphragm or piston design and it was probably getting some corrosion with moisture and getting stuck. I was going to try to get some permatex never seize spray in there, pressure it up manually with an air gun a few times and see if that does the trick. However now with that electric strain gauge being a possibility of what's in there that has now thrown me through a loop. Seeing as how never seize has copper and aluminum lubricant, it's conductivity might mess up the sensor. I really wanted to use that for its anti-corrosive properties but I may have to opt for a non-conductive lubricant instead. If anyone has any ideas that might help I'd appreciate it.
I have a Danfoss 031E021566 mechanical pressure switch controlling the well water pump for my house. The switch that it replaced had failed by fusing in the on position - luckily I was home at the time and heard the pump running unusually long, and managed to shut it off before the pressure tank exploded. I had never considered using an electronic switch instead, so thanks for this video!
Awesome video demonstrating how an electronic pressure switch works. Great to see an application of voltage diver, wheatstone bridge, op-amp and mosfet to complete the system.
I work with espresso equipment, nearly every machine has a pressure switch. Controls steam pressure in the boiler, definitely a regularly replaced part for us.
I work on an oil production rig in the Gulf of Mexico, we use them for our main compressor unit, firewater pumps, and our oil wells piping, as well as a few other systems on the platform that I’m forgetting about.
You cant make it more interesting. I have some equipments like stucco sprayer which has pressure transducers. Your video has simplified the tech and understand them better. Thanks a lot for imparting knowledge.
We have a lot of wells with pressure tanks here and the switch to turn the pump on when the pressure gets to low. They go out a good bit. I used to do about three a summer when I was doing house maintenance for customers.
If you have learned something from this man's video's, how about giving him a thumbs or buy him some coffee... I have in the past and appreciate his time making these videos easy to understand..
Vacuum gauges work totally different. It's very hard to measure deep vacuum or the lack of pressure. Instead of something bending or flexing it measures how much heat can be disapated, less pressure equals less heat losses.
Used to switch on the brake light from the front master cylinder of my 1974 Norton Commando, and oddly enough, the rear brake circuit on my 2004 Sportster.
Its a common occurance in a gas or diesel powered vehicle used for oil mainly. but can also be used in conjunction with other things. sometimes they are called a sender switch.
Senders have a variable output (like for the fuel gauge in an automobile) Sensors are binary state (open/closed) so an old fashioned vehicle like mine might have a sender for the gauge but also a sensor for the low oil pressure idiot light.
Is it really using a floating gate drive voltage to turn on the MOSFET at 06:22 In video? Or are the 2 power supplies referenced to common ground via their power cord ground which not shown in the schematic and the breadboard circuit. Sometimes over simplification leads to more questions. Otherwise, awesome video! Thanks!
We are replacing failed $800 pressure switches with $200 sensor on water system. The PLC will then be able to adjust setpoints remotely for pump monitoring.
I'm looking for a compound pressure transducer for the suction line of an ultra low temperature chiller. I need at least -15 to 200 PSI. The suction line can get as cold as -80F I'm curious if this pressure transducer connected to this cold suction line will cause problems with the pressure transducer?
Prodigy The Engineering Mindset Thank you very much helpful information video Take care and have a great day The Engineering Mindset From Nick Ayivor from London England UK 🇬🇧
Do you happen to have a video of strain gauges /amplifiers ? I came here for pressure switches but on my line we have transducers that measure tension based off load cells that have strain gauges and the load cells are connected to an amplifier (summing box). So now im curious how the circuit and physics of it work. Its a tension control loop/PID btw with motor drives etc
My furnace has a diaphragm style pressure switch. One time it was triggering and shutting off the furnace. The problem turned out to be a dead rodent or a dead bird in the vent. You should never blow into one of these switches to test it, they are that sensitive to damage.
No wonder why most of mechanical devices/systems have been overshadowed by their electrical (electromagnetic, electronic or electro-optic) counterparts.
Hello, I would like to use your video in a free training on pressure switches. For this, I would like to request your authorization to use it as Creative Commons. Thank you.
We use one as a safety control to alarm the operator/engineer when the nitrogen gas levels have dropped; this also shuts down the machine. Without one, we would have products returned to us which will damage our relationship with the customer and a potential of losing of on millions.
@@EngineeringMindset then make a separate video for it, cause we can learn how to read schematics of complicated circuits from you, you teach well🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻

Thank You
Sir, pliz add subtitle
Isn’t a strain gauge a moving part?
Psi swich normaly opon selfty swich using
I wish these vids were used in official education. Simple, straight to the point, something I never really had in technical school.
We actually use his video in our highschool class
Use it everyday for safety on boiler controls for steam generation. There’s also analog pressure sensors. Would be great to see how it create 4-20mA
Man do I love this channel. Extraordinary good explainations, and really easy comprehensible animations. If learning would always be so easy.

Tested these for years as well as your sponsor. Wish i had this when I started. Regardless, a phenomenal video.
Really very important and accurate knowledge and explaining skills u got man
Since the strain guage is moving surely it too wears out eventually?

Are these strain guages same as piezoelectric transducers?
Thanks for the video 👍👍
Literally was searching for something like this. Thank you!
Usefull as always. Thank you!

ironic i replaced one of these on an RO unit last week and now you made a video on it.
sir that's a great content . In one content we learned many topic and your explanation was great to easy understand.
Great Work 🥳🥳🥳 Thank you 💜💜💜
Thank you so much.🥰🙏
Many thanks for your information and useful videos

Please make a video on tan delta test
how do you make the cool overlay effects? like the current flowing effect on the breadboard at 0:08 ?
Hi
Can we get one video on Load bank used for generator.. Its construction parts and applications
Good information video

There is another *new feature*
Replay Chapter in UA-cam
We are replacing failed $800 pressure switches with $200 sensor on water system. The PLC will then be able to adjust setpoints remotely for pump monitoring.
Can u make a video of how speed bumps /speed humps slows down a moving vehicle? Is it principle of conservation of energy.?
Those switches are used in hydraulic elevators to control over and/or under-pressure in the hydraulic system that moves the elevator-cabin.
Unbelievable explanations
Very nice
Plz keep making videos like this

well explained ,,thanks
Outstanding!👍👍👍👍👍
See a lot of thosr 2 prong cylindrical ones for high and low pressure limits on the refrigeration lines on hvac systems
In AWP or cherry pickers pressure switches were used to control the overload system
Great video
thanks :)
It would be good if you could add a calibration of instruments in same video when you explain them
Hi, I’ve been looking for one to replace the dead one on my compressor. The only one I’ve found is 12v. Can you point me in the right direction?
Can piezoelectric devices be used here?
This is outstanding - clear and complete. Thank you so much.

excellent pressure switch electrical & mechanical function # 👍 🇵🇰
You're Amazing , i love your videos , keep up.
Hey I need your help what is the best pressure switch of flow switch for low water flow
Cracking Video
Awesome!
Can you make about the op amps, pls?
Mostly used in HVAC system for protection of compressor
I wired in countless numbers of pressure switches on the Apache helicopter
Good

Nice ✌😎
In cnc machine,air compressor
I guess pressure switches are used also with vacuum pumps in vehicles.
No wonder why most of mechanical devices/systems have been overshadowed by their electrical (electromagnetic, electronic or electro-optic) counterparts.
See our new video on how to build mechanical versions of electronic circuits? Watch here: ua-cam.com/video/Zv9Q7ih48Uc/v-deo.html
Some of those pictures look like pressure transducers?
I've saw PS on Ducts.

You didn’t explain how the comparator works and it’s circuit schematic
Correct. That would be beyond the scope of this video
