Elpro and OleumTech Wireless systems
Temperature measurement of a Kiln.
Rotary ovens, or Kilns, require precise control of the internal temperature. Formerly, we used copper rings with shoes as a contact called “ Sleeping Ring“. This system is very costly in maintenance and is now replaced by wireless systems like Elpro and OleumTech. Wireless systems are not energy intensive and require very little maintenance.
Drexelbrook Level Switch
Level Switch in aggregates.
Cement is made up of a multitude of different aggregates. The detection of high or low levels is accomplished with Drexelbrook RF admittance level switches that offset the deposit of dust and particles in the air generated by the process and material handling. This increases the lifetime of level sensors and significantly reduces the periodic maintenance normally required.
Plugged Chute Detection.
For plugged chute applications, Drexelbrook has a switch plate RF admittance that is installed in the chutes and is the same level as the walls. Thus, this system can not obstruct the process and can not cause blocking. This probe also has the anti-clogging Drexelbrook system and requires no maintenance.
Williamson’s Infrared Pyrometer
Rotating oven temperature measurement.
Williamson’s infrared pyrometer for the oven temperature detection installed in the flamme side can read the bed of the rotary kiln without being affected by the flame. In addition, the pyrometer can read through certain gases contained in the rotary kiln such as H2S which is seen as a wall for some infrared pyrometers. Williamson allows greater accuracy of reading and better control.
Drexelbrook & SOR hydrostatic probes
Quarry lake level reading.
The hydrostatic sensor can give real-time lake levels and control the pumping of water. This reading is critical for quarries and is very often transmitted to the control room with wireless systems like Elpro and OleumTech.
Level of molten tanks measurement.
Optech’s laser has a technology capable of reading the molten liquid level of aluminum although it is like a mirror. The pulsed laser technology developed by Noranda Technology makes Optech a leader in the field of laser. It can read the level remotely without contact. It can also be installed at a very pronounced side angle, which facilitates installation and protects from fragments and high temperature during pouring.
Aluminum ingots level measurement.
At the finished stage, aluminum ingots have become solid and its color matt. It is very easy to measure their heights with a non-contact Dimetix laser to check their sizes before shipping. The laser is useful in this application because the ingots are generally still very hot.
Hardy scale & LSI
Carbon balance mixer weight measurement.
During the preparation of the carbon recipe blender, the Hardy scale is very useful to measure the weight of the different powder components used in the recipe. Its anti-vibration system allows it to accelerate this mixture accurately and increase the pace of production.
Hardy scale & LSI
Anode weight measurement.
When the anodes are molded and transported suspended on a conveyor, a conveyor section is converted into a scale to ensure quality control of the weight of anodes delivered to production. Hardy scales are adapted perfectly to read the weight without the vibrations generated by the suspended transport of anodes and thus gives the exact value of the weight of the anodes.
Wilcoxon Vibration transmitters
Vibration measurement of bearings of the rotary kiln.
The bearings are huge and very critical on rotary kilns. It is therefore important to read the vibration in real time. Analog output Wilcoxon Vibration transmitters remain a very economical solution and can carry the signal over long distances without compromising the accuracy of it.
Flame detection of the rotary kiln.
Each burner from which emerges a flame must be equipped with a flame detector. Iris has a high-performance system that can detect the flame in several ways. The flame detector can combine the infrared and ultraviolet technologies in the same detector and is also equipped with a gas explosion frequency detector on the burner. It is very effective in eliminating other flames in a multi-flame system.
Hardy scales & LSI
Conveyors weight measurement.
In aggregates, asphalt and stone transportation, conveyors are used as a common means of transport of raw materials and finished goods. The measurement of weight on the conveyor is the most common way to measure the product. Hardy scales, with their anti-vibration systems, give an accurate reading of product weight that allows a uniform and repetitive dosing. This measurement can, thereafter, be wirelessly transmitted by way of the LSI modules.
Dimetix & Optech lasers
Level measurement in tanks.
In quarries, there are often reservoirs or aggregate piles that are huge. The laser is the best technology for reading the level of these piles. The laser is also the only technology that can read the level at an angle. The Optech laser is very good in dust-related applications.
Thermo Fisher Gamma Switch
In high or low level applications that are very abrasive (like stones of many sizes), Thermo Fisher’s gamma level switch is a very good solution. Its technology is very long-term (20 to 30 years). This switch can be installed without stopping the process and it is mounted outside of the chutes or tanks.
