  • Historical Introduction Summarized History of Air Heating and Sheathed Heating Elements
    Jacques Jumeau English version History of technologies linked to heating. Chapter 5 Historical introduction Summarized history of air heating and sheathed heating elements Copyright: Jacques Jumeau 1st edition 2015/11/26 Copy is allowed, provided you cite the origin: Ultimheat Museum 1 Update 2019/02/20 Historical introduction Summarized history of air heating and sheathed heating elements The invention of sheathed heating elements comprising a metal tube swaged around a coiled heating wire, and which is insulated by compressed magnesia, was an essential step of the electrothermics development. Thanks to their mechanical strength, impermeability and resistance to corrosion, these are the most professional heating technical solutions. The appearance of these heating elements, now universally used, was the result of a combination of different advanced techniques of the early 20th Century. Over the last two decades of the 19th Century, the emergence of electric heating had revealed the need to find reliable solutions for converting electricity into heat. The first electrical heaters were platinum wires (inherited laboratory equipment), nickel silver or even iron. Research carried on resistive elements with greater resistivity and good temperature resistance. On October 12, 1878, St. George Lane Fox-Pitt filed patent in England 4043, in which he developed the use of electricity for lighting and heating. This patent, based on the use of platinum filaments, was not followed for heating but it was the basis for the development of electric bulbs. In 1884, French Henri Marbeau, a pioneer in the manufacture of Nickel in New Caledonia and France, founded the company "Le Ferro-Nickel'' in Lizy sur Ourcq".

  • On the Electrical Behaviour of Metal Mesh Heating Elements for Resistance Welding of Thermoplastic Composites
    This is an Accepted Manuscript of an article published by SAGE in The Journal of Thermoplastic Composite Materials on 2015, available online: DOI: 10.1177/0892705712475012 CHARACTERISATION OF A METAL MESH HEATING ELEMENT FOR CLOSED-LOOP RESISTANCE WELDING OF THERMOPLASTIC COMPOSITES Irene Fernandez Villegasa, Harald E.N. Berseea aStructural Integrity and Composites, Faculty of Aerospace Engineering Delft University of Technology, Kluyverweg 1, 2629 HS Delft, The Netherlands Corresponding author: Irene Fernandez-Villegas, T:+31152789745, F: +31152781151, [email protected] ABSTRACT Resistance welding is one of the most suitable and mature welding techniques for thermoplastic composites. It uses the heat generated at the welding interface when electric current flows through in a resistive element, frequently a metal mesh. Closed- loop resistance welding relies on indirect temperature feedback from the weld line for process control. Its implementation is more complex than the most common open-loop welding, but on the contrary it does not in principle require the definition of processing windows for each welding configuration and it allows for constant-temperature welding. The temperature at the welding interface can be indirectly monitored through the resistance of the heating element. The relationship between resistance and temperature, expected to be approximately linear for a metal mesh heating element, can then be used to translate the welding temperature into a target resistance value for the process control routine. Despite the apparent straightforwardness of this procedure, the research results presented in this paper prove that different types of characterization tests yield different 1 This is an Accepted Manuscript of an article published by SAGE in The Journal of Thermoplastic Composite Materials on 2015, available online: DOI: 10.1177/0892705712475012 resistance versus temperature relations for a metal mesh heating element, which can lead to significant temperature deviations when used in closed-loop processes.

  • How to Determine If an Electric Heater Is Good Or Bad Using an Ohmmeter By: Admin - November 06, 2020
    How to Determine if an Electric Heater is Good or Bad Using an Ohmmeter By: Admin - November 06, 2020 (abcimg://ohm%20meter) Your Watlow® electric heater (/en/products/heaters) is designed to hold up to years of use in some harsh industrial conditions. Over time, the electric insulation may deteriorate and you may experience performance issues. Both heaters and power and temperature controllers are subject to performance issues, so it is important to inspect both for signs of wear and breakdown. Here we will cover all you need to know about ohms, ohmmeters and signs that your electric heater needs to be repaired or replaced with a new Watlow unit. Understanding ohms Before you check your heating products to see whether they are working effectively, it is important to understand ohms, watts, volts and amps. These electrical units allow you to compare the output of various heaters and identify signs of an inefficient or failing heater. According to Ohm’s Law the current is equal to the voltage divided by the resistance. This can also be expressed in the following equation: I = V/R (where I = current, V = voltage and R = resistance) The current of a thermocouple (/en/products/sensors/thermocouples)or other electrical device is measured in amps, the voltage is measured in volts and the resistance is measured in ohms. A high level of resistance is necessary to transform electrical energy into heat energy. The thickness, material and other factors of the conductor affect its efficiency and available temperature range. Resistors are made of materials that have a high level of electrical resistance.

  • The Resistance Heating Element Is the Mainstay of Electric Heaters, Furnaces, and Electric Clothes Dryers
    MARK GOODSON, PE TONY PERRYMAN, EIT KELLY COLWELL The resistance heating element is the mainstay of electric heaters, furnaces, and electric clothes dryers. Resistance elements are found on electric furnaces and on heat pump systems that use resistance heat for backup or emergency purposes. The typical resistance heating ele- ment for a heater or furnace consists of a length of coiled resistance wire configured in a 5000 watt configuration. Photo 1 shows such a resistance coil for a furnace. On a dryer, typical wattages for resistance elements are between 5000 and 6000 watts. The resistance heating element is akin to a light bulb filament, in that electric current is applied and heat is generated. Just as light bulb filaments fail over time, so will the resistance element. Eventually, the heating element will fail with a parting arc; the splattered molten metal, often nichrome, is capable of igniting combustibles that it may land on. We have seen numerous fires caused by the ignition of plastic Photo 1 ductwork, dust accumulations, and air filters. Obviously, filter loca- tion and ductwork construction vary with each installation, such that not every failed resistance element will cause a fire. We examined eight 5000 watt heater elements, installed in 3 sepa- rate furnaces in the same building. The wattages for the eight elements, A second mode of fire causation occurs when the element fails, which were installed new in 1989, are as follows: and then ‘welds’ itself onto surrounding metal. While probably of little concern from a fire standpoint on a 120 VAC appliance, on a 240 VAC 5042, 5114, 5162, 5270, 5148, 5075, 5070, 5221.
