Reliable Level Switch For Fly Ash Silo

Posted on 1. Feb. 2006 - 04:50

Hello

For a reliable „high level“ detection of fly ashes, I recommend to measure with our rotating paddle level switch MaihakMBA 200. This electro mechanical measurement has been approved in this application for many times:

- proven in many fly aches applications

- reliable measurement

- even for high temperatures

- product touched parts are made of stainless steel

- fair price

Fly Ash Silo High Level Detection

United Conveyor Corporation (UCC) typically provides rotating, paddle type material sensors for high level detection in fly ash silos. We have used such sensors for the past 30 years or more, and have found them to be very reliable in this application.

For further information, please contact me at jasonkaull@unitedconveyor.com.

There are a number of technologies you can try with the following tips. I will leave out the RF Capacitance sensors because you say they don't work in your silo.

Electromechanical rotating paddle switch - lowest cost but may have to be replaced if material loading shock damages the vanes.

Single rod vibrating sensor - Low cost, reliable in most powders when not fluidised.

Double rod or fork vibrating sensor - Excellent reliability but may switch if the material is very sticky and clogs the forks

Non contact microwave switch - Most expensive but most reliable being mounted outside the silo. The only draw back is you will have to install viewing windows (perspex or plastic or crystal glass for high temperature) in your silo because the microwave will not penetrate the steel walls.

Check out the Level switch section on the Endress+Hauser web site for details of each product and the nearest sales office to you

This is a perfect application for our Digimatic level probe. It has built in build up compensation to eliminate the effect of material adhering to the probe which may be the cause of the problem in this case.

We have supplied many probes for this application with complete success

Another option is, if your silo is not too big, is load cells on you silo base. Program in know weight of product or products and set scales to tell you how full your silo is. No sensors in product and no moving parts.

Hello, Why you don't use a volume measuring system for fly-ash.

We supply non contacting 3D volume/level systems for silo's up to 70 mtrs.

Hi,

Fly-ash is not so easy, so if you spend some monye go for the total solution,including volume and visualisation of your silo.

Please look at : www.apm-solutions.com/mediakit and see the future for dry bulk silo's measuring and inventory control.
