EMG Automation GmbH products

The EVK edge sensor positioning device and the EVM centre sensor positioning device are used for the non-contact strip edge and strip centre sensing of steel strip. The device, which is highly reliable and unsusceptible to external interference, visually detects changes in the edge and/or centre position of the strip.

The CCD Pro line scan camera provides exact detection of strip edges and the strip centre position. With an integrated control unit and interchangeable lenses, it is extremely flexible in its application. Simple operation and maintenance are thereby guaranteed.

The measuring principle of the SMI sensor family (Strip Measurement Inductive) is based on electromagnetic induction. Two centre sensors are arranged at the strip edges at right angles to the strip pass line level and symmetrically to the system centre, and they are configured in such a way that the strip passes between the sensors as centrally as possible. The centre sensor that is located above the strip functions as a transmitter and the opposite sensor functions as a receiver.

The all-rounder for strip guiding and quality assurance systems.

The HR hydraulic controller and the HA hydraulic power pack generate reliable hydraulic energy for any power range. A HR hydraulic controller is a HA hydraulic power pack with a servo valve, which regulates the volume flow of the fluid. Standard hydraulic units fundamentally consist of an oil tank, a motor/pump assembly and a filter. Pressure-regulated pumps with variable displacement are used. If cooling is required, either air or water cooling units may be used.

A HST hydraulic control system is used wherever installation space is at a minimum. It can even be used in close proximity to the hydraulic cylinder. The HST system is supplied by the central hydraulic system or a hydraulic power pack (HA). The main component of the hydraulic control system is the EMG servo valve (SV).

Servo valves are the most important components in any electrohydraulic control system. Our rotary valve design with gap height control ensures minimum friction loss, high repetition accuracy and a large power range for single-stage valves. Based on our extensive experience with industrial applications and control hydraulics, we decided to equip the valves with a manual operating mechanism for functional control and for setting procedures.

Based on a simple functional principle, the ESZ electric servo cylinder ensures maximum positioning accuracy even when subjected to the harshest environmental conditions. The preferred place of installation is in the furnace area, as flammable hydraulic oils are undesirable in the hot area. Utilisation on a carriage system, where the installation of hydraulics is often difficult or even impossible, is not a problem.  The ESZ represents an alternative to hydraulically operated variable speed drives.

The ELDRO and ELHY electrohydraulic thrusters from EMG ensure a safe and "gentle" braking process in combination with modern drum and disk brakes. In addition, they ensure personal safety and the safety of machines.

The electro-hydraulic system of the ELDROdynamic^® thrusters in conjunction with their easy integration into brake systems and the simple electrical commissioning result in the following features for a wide range of application conditions:
