Hello great vid. I am planning to use a capacitive proximity sensor for a hand held device. It will detect studs behind drywall, potentially used to detect live wire behind drywall and also be used as a moisture meter to detect the amount of moisture in drywall. Would this sensor be a good fit for some or all of these uses??

@realpars

8 ай бұрын

Thank you for your question. Your project is quite intriguing! While there are existing equipment options in the market that can fulfill most of your requirements, if you're interested in experimenting, it could be an enjoyable endeavor. To get started, you'll need a Capacitive Sensor with sensitivity adjustment. Next, you'll need to calibrate the sensor for each specific item you intend to test. Therefore, acquire a separate sensor for each item and configure it accordingly. One potential challenge you may encounter is when it comes to moisture sensing. Anticipate that you might receive false readings because you'll need to set the sensor to the minimum moisture threshold you're targeting and maintain that setting consistently. Any moisture level exceeding your chosen threshold will trigger an output. Remember that all your tests should be conducted on drywall of the same size and thickness, with a predetermined +/- tolerance you've selected. Best of luck with your project! Happy learning.

Capacitive sensors come in various configurations, but as useful as they are, they do have limitations.

Plastic sheets and -single-layer paper objects are difficult to detect, but newer capacitance sensors and LED laser sensors can be used successfully for this purpose.

Hi Osman, Thank you for your question, and we'll do our best to grant you some guiding answers. It seems that some essential engineering data of the sensor was not provided in your inquiry, making it challenging to offer a complete solution. When mentioning the screen, I'm unsure about your specific engineering requirements. However, one approach to address your needs could involve using a PLC with a custom program and connecting it to an HMI panel. Additionally, if your capacitor sensor's current load capacity is 24V/500mA, employing a counter relay connection properly wired to the sensor should suffice. I would recommend checking out RS-online.com, an online electronic store where you may find the necessary components for your project. Hope this helps!

For optimal results, it is advisable to employ two distinct sensors tailored to your specific requirements and application-one designed for glass and another for plastic.

Thank you for your inquiry. The dielectric plates and electronic circuitry are integral components of the sensor and cannot be separated. To achieve your desired functionality, you can consider obtaining a capacitor sensor along with an electronic module designed to power the sensor and receive its output based on your specific configuration. Subsequently, you can configure the module to transmit a signal to a PLC or the intended device. For further guidance and potential purchase options, I recommend exploring the following links from companies that specialize in sensor technology: Keyence www.keyence.com/products/sensor/ RS Components us.rs-online.com/sensors/proximity-sensors/ We hope you find these resources helpful in pursuing your project.

Hello koko Kofi Mensah, Thank you for your question. If the sensor is electrically hooked up, you can tell by the material you put in front of it to sense. The capacitive sensor will detect non-ferrous objects like plastic or paper and the inductive proximity sensor detects ferrous metals only like steel, iron, etc. If they are not electrically hooked up, you must have the datasheet from the manufacturer. Happy learning!

I do have a question. In the example of water in a glass. If we set the sensing range to the distance of the cup, the sensor will detect the cup, with or without water. The water will only change in height (when being filled) not in distance because the distance difference in this case will literally be the thickness of the cup? So can you adjust the sensing range to the thickness of the cup or do you use the sensor to detect height difference not distance difference?

I have often used a capacitive sensor on the side of a glass or plastic tank. I mount the sensor against the tank wall and then adjust the sensitivity so that it is "just not detecting" the tank wall. As the tank fills, the change of capacitance due to the liquid level will be sensed by the sensor. The sensor needs to be selected to be able to have a field much deeper than the wall thickness and have a way to adjust the sensitivity.

hello! can i ask a question. do the capacitive proximity sensor have a measurements size limit of an object or what is the smallest size or measurement of a paper and plastic that capacitive proximity sensor can detect? are there any minimum sizes that the sensor can detect? because we can't find any study that can support our research, and do you know where can we find it. thank u, i hope u can see my comment

@realpars

There are a couple of rules of thumb regarding target size (I do not know where these came from originally). The target should be at least the size of the sensors active surface. For a standard 18mm sensor, that would be a target of at least 18 mm square. The second rule of thumb states that the target should be at least 3 times the sensing distance, so using the same sensor, at a sensing distance of 30mm, the target should be at least 90mm x 90mm. The larger size should be used when both rules are applied. Of course, these are design considerations, and validation of these sizes would need to be made in the field during testing.

Human parts would block all light, which could be programmed to be ignored.

If you are referring to the wiring, the cabling typically is shielded. If you are referring to the device itself, many capacitance sensors are RFI "immune".

I could have three sensors each tuned for a different capacitance range along the same conveyor and perhaps be able to detect three different materials as they pass by, but this is not easy to do unless the capacitance values for the materials in question are vastly different. Even then, it is likely one or more of the sensors will detect multiple materials.

Hi Stalin, Identification is not easy because both NPN and PNP sensors look identical and therefore almost impossible to determine by examining them physically. Here’s another method you might use if you know the sensor is functioning correctly. Let’s assume that the power supply is 24VDC and the sensor is a normally-open type. First thing to do is connect a voltmeter from the output (black wire) to the power supply return which is connected to the Blue wire. Secondly, activate the sensor which will cause it to close. If the sensor is a PNP type, the voltmeter will read 24VDC. If the sensor is an NPN type, the voltmeter will read 0VDC. If the sensor is normally-closed, the voltmeter readings will be opposite during sensor activation.
