Selection of blockage switch
Thread Content
I would like to ask: for lumps of size 0–500 mm that are transferred using a conveyor belt, what type of level switch is suitable for checking whether the feeding chute is blocked?
It seems the image didn’t get uploaded; let’s try again
Are you a designer? Or a user? Planning to do it on your own?
It seems a bit tricky – should a weight sensor be added under the pouring chute? Too much filler will definitely cause an excess weight
I am a user who needs to purchase a clog detection device for use in my project

The anchor is in different positions; if there’s a blockage, material will accumulate and come into contact with it. This requires DIY work, involving the use of both hands and intelligence on site. What do you think? :lol
Hello, this device can use a Doppler switch to detect whether there is movement of the material, and it outputs a digital signal; it’s a contactless solution. We have developed many such devices – feel free to get in touch with me.
I also have a blockage switch on the boiler feeder here; I’ve tried two different measurement methods, and to be honest, neither of them worked well. 1. Radio frequency admittance is used to check for coal blockages at the material level, but it often gives false alarms. 2 Measurement is carried out through a rotary-type level switch, at the rotating part
2 It is measured using a rotary-type level switch; it worked fine at first, but after about half a year, coal ash entered the rotating parts, which blocked the probe and made it impossible to take measurements.
Both radio frequency admittance and rotary resistance type level switches are contact-based level sensors; they should be able to perform measurements. The concern is that their performance may decline over time. Another concern is that if the particle size of the material is too large, it might damage the probe
