Pyrometer and Infrared Thermometer

EEC is an established name in supplying of all types of Pyrometer and infrared thermometer. We offer complete range of pyrometers to suit different applications. Pyrometers are temperature measurement instruments that operate on the principle of infrared radiation, i.e. they detect infrared radiation of objects to determine the temperature. An optical pyrometer determines the temperature of a very hot object by the color of the visible light it gives off. The color of the light can be determined by comparing it with the color of an electrically heated metal wire. In one type of pyrometer, the temperature of the wire is varied by varying the strength of the current until the operator of the instrument determines that the color of the wire matches the color of the object. A dial, operated by the current that heats the wire, indicates the temperature.

A radiation pyrometer determines the temperature of an object from the radiation (infrared and, if present, visible light) given off by the object. The radiation is directed at a heat-sensitive element such as a thermocouple, a device that produces an electric current when part of it is heated. The hotter the object, the more current is generated by the thermocouple. The current operates a dial that indicates temperature. With a huge pyrometer product portfolio, we provide solutions for nearly every application request. Special solutions that are not listed below can also be quickly adapted to customer or application specific specifications.

Noncontact infrared thermometers in steel manufacturing process where temperature monitoring is critical to productivity and product quality. Every section of the steel manufacturing can benefit from temperature monitoring.
Raw Materials for Steel Production
Monitoring temperatures of iron ore, lime, coal and coke insures that the basic raw materials have achieved the right characteristics and prevents critical conveyor belts from being damaged. Continuous scans of stove dome temperatures are a requirement for maintaining correct operation of the blast furnace.
Steelmaking – Blast Furnace

• Stove Dome : Thermal scans prevent overheating and premature damage to the refractory bricks. Not all our products are shown here so if you have a specific requirement, please do contact us and we will assure you of our personal attention to your needs. This is our specialty, we don’t just present our customers with a list of products and leave them to it, we guide you step by step.
• Molten Iron : Temperature monitoring during tapping ensures continuous feedback and product uniformity.
• Torpedo Car : Linescanning finds refractory failures and avoids costly and dangerous metal spills.

Continuous Casting

Using infrared thermometers accurately gauge cooling requirements of slabs, billets, or blooms to ensure product uniformity throughout, and provide equipment operators with immediate temperature information vital to the cooling process.

Rolling Mills
Infrared temperature sensors accurately measure strip and sheet temperature so that rolling mill stands can be efficiently set to match the steel’s temperature. IR sensors can also be used to detect the presence of hot metal to accurately time roll stand operation.
Tube/Pipe Mills
Welded tube relies on accurate measurement of weld seem temperatures to insure 100% integrity of the seal and prevent bad or low quality tube. Monitoring the billet temperature in pipe mills allows the operator to adjust rollers, which results in reduced process downtime.
Rod/Wire Mills
Thermal scans of billet exit temperatures allow the operator to adjust rollers and reduce process downtime. Sensors mounted at the layering area control cooling of overlapping coils to improve product quality.
Heat Treating
Ratio IR thermometers allow accurate temperature measurement of parts often obscured by smoke, steam, and quench oil in an EMI environment. Factory operators can selectively control temperature measurement of heat treated parts, resulting in significant energy and time savings.
Steel Coating
Sheet temperatures can be monitored before and after coating to insure the coating will bond and have the desired thickness.
Forging
Infrared sensors measure work-piece temperatures without interfering with the process to insure that correct metallurgical properties, such as grain size and structure are achieved. Monitoring temperature reduces heating costs by preventing billet overheating and reduces machine and die maintenance by identifying under heated billets before working.
