EMG sensor technology ‒ the basis for an optimum strip guiding system Individual sensor solutions: Inductive sensors: For metal strip production, treatment and processing, the material - which is supplied in the form of coils - is unwound and then fed to the production process. In most cases, it is rewound into coils thereafter to allow convenient transport. Due to its geometric shape, metal strip material tends to run unevenly from the deflector rolls in the treatment line. Determining the strip centre position is the single most important goal for all strip control solutions. The strip...

Inductive strip position measurement SMI Operating method: Available variants: symmetry properties of the SMI sensor family offer an improved centre measuring accuracy as well as various possibilities to achieve your individual requirements. In this setup, two centre sensors are arranged on each strip edge at right angles to the strip pass line level and they are configured in such a way that the strip passes between the sensors as centrally as possible: Design of all SMI variants: Compact measuring frame with integrated evaluation electronics. Optionally available with a 30 m connecting...

Additional inductive sensors Strip centre measuring system for use in aggressive and humid environments, such as in pickling or cleaning lines with medium temperatures of up to 80 °C. Strip centre measuring system for strip temperatures of up to 300 °C (max. ambient temperature at the sensors: 130 °C). Strip edge sensor for metal strip in areas where liquids with temperatures of up to 80 °C are sprayed or for metal strip with a overlaying protective film at a measuring accuracy of +/- 1 mm. Version: Four encapsulated coils in a tube configuration for on-site insertion (by the customer) in...

Inductive strip edge position measurement VKI3 Operating method: Customer benefits: EMG's VKI3 measuring device uses an inductive measuring principle with a coil system, which is designed to reliably detect the precise position of the edge of metal strip and foil material in a contact-free manner, even when subjected to the harsh ambient conditions of a rolling mill where there is a high presence of rolling oil, atmospheric pollution and dirt. On one side, the inductive EMG VKI3 measuring instrument detects the absolute strip edge position of all metallic materials as a result of the eddy...

Optical strip edge / strip centre measuring systems EVK / EVM Operating method: Customer benefits: Technical data EVK/EVM: The EVK edge sensor positioning device and the EVM centre sensor positioning device are used for the non-contact strip edge and strip centre measuring of metal strip material. The device, which is highly reliable and unsusceptible to external interference, visually measures changes in the edge and/or centre position of the strip. precise and reliable measuring accuracy, as the system is insensitive to fluctuations in strip height EVM: strip centre guiding system...

Optical strip edge / strip centre measuring systems EVK / EVM Alternating light measuring receiver LS: The LS 13 and LS 14 alternating light measuring receivers are designed as photoelectric edge sensors with a large measuring distance between the light emitter and measuring receiver. The alternating light eliminates the influence of DC light and thereby ambient light. The LS 13 is used as a measuring receiver and the LS 14 is used as a reference receiver. The high-frequency HF light (2 kHz) emitted by an external alternating light transmitter (e.g. LLS) is transmitted via the front lens to...

Radar-based strip centre measurement in the furnace EMG-Vivaldi® Operating method: A particular challenge is to measure the strip position in extreme environments, such as in annealing fur-naces. EMG has many years of experience with its IMH inductive strip centre measuring systems in furnaces with temperatures of up to 1100 °C. Despite IMH, there is often a desire to determine the strip centre position in furnaces without having any active or interfering sensor elements in the furnace itself. The EMG-Vivaldi sensor is located outside the furnace and conducts its measurements through the...

Radar-based strip centre measurement in the furnace EMG-Vivaldi® Technical data: System architecture: Strip thickness Strip temperature Strip position sample rate Centre position accuracy no cooling is required for temperatures up to +70 °C on the furnace outside wall and an ambient temperature of up to +50 °C (optional water cooling) Installation position observe the required clearances to metallic parts in the furnace; the exact dimensions are dependent on the individual conditions of the line (in particular, the width of the furnace and the minimum strip width) Sensor cable The other...
