3, Industry Applications:

1) Hydraulic Components – Application of EMG Automation servo valves in industry

In any electro-hydraulic control system, the servo valve is the most important component. The design with rotating spool and gap adjustment ensures minimal friction loss, high repeatability accuracy, and a large power range for single-stage valves.
Based on our extensive experience in industrial applications and control hydraulic systems, we have decided to equip manual adjustment devices for functional control and setting steps.
 

Customer Benefits:
a servo valve online flushing
a suitable for low pressure
a ensures minimal friction loss and high repeatability accuracy
a high power range for single-stage and two-stage valves
a optional single-stage or two-stage configuration
a high reliability
a easy maintenance

2) Application of ESZ electric servo actuators

Actuators suitable for harsh environments

A simple functional principle allows the ESZ electric servo actuator to ensure ** positioning accuracy even under the most severe environmental conditions. Since flammable hydraulic oil is unsuitable for high-temperature areas, the ** installation location for ESZ is in furnace zones. Installation of hydraulic systems is often very difficult or even impossible, but this problem is resolved by using the transport system. The ESZ electric servo actuator is used as a replacement for hydraulic variable-speed drives.

Significant advantages of electric servo actuators include:
a high environmental compatibility
a lower energy consumption
a low operating and maintenance costs
a no flammable hydraulic oil

EMG uses a planetary gear screw system (PGT) in the electric servo actuator, which offers the following advantages compared to traditional solutions:
a simple functional principle
a compact design ensures high power transmission
a high positioning accuracy
a permanent zero-backlash power transmission
a no intermediate gears required

Mounting size determines power rating:
10 kN, 25 kN, 50 kN, 100 kN

Mounting size determines rated stroke (standard stroke):
100 mm, 200 mm, 300 mm, 400 mm, 500 mm

Larger strokes are in increments of 100mm

3) Application of EVK edge sensor positioning device / EVM centering sensor positioning device

Photoelectric strip edge guiding and centering system

EVK edge guide sensor positioning units and EVM centering sensor positioning units are used for non-contact strip edge guiding and centering in steel strip inspection. The unit offers high reliability and is immune to external interference. The sensors detect changes in strip position during edge guiding or centering.

The positioning unit equipped with the high-frequency alternating light sensor gLS13/LS14 is motor-driven to detect the strip edge position and suppress ambient light interference. The sensor detects edge position shifts caused by changes in strip width or lateral strip deviation.

Advanced control circuits drive a DC motor to move the gLS13/LS14 positioning unit or actuators (g servo valves or g electric servo push rods), ensuring that the sensor’s detection range is always half-covered by the strip.

The reference measurement principle compensates for contamination of the light source emitter. This involves aligning the light spots on a measuring sensor and a reference sensor within the measurement system. The measuring sensor detects changes in the strip edge position, while the reference sensor monitors the brightness of the light spot.

Customer Benefits:
a precise and reliable measurement accuracy is unaffected by fluctuations in strip height
The distance between the a sensor and the light source can reach 4 meters
a high reliability and simple operation
a quick and easy installation, reducing commissioning time (minimal installation space)
a reference measurement principle, effective compensation for contamination
a suitable for harsh production environments (e.g., pickling lines, cold rolling mills, etc.)
a protects against ambient light using high-frequency light modulation

4) Application of SMI inductive strip position measurement systems

The measurement principle of the SMI series sensors is based on electromagnetic induction. On both sides of the steel strip, perpendicular to the direction of strip travel, two centering sensors are arranged symmetrically. This symmetrical design allows the steel strip to move along the centerline relative to the centering sensors. The sensor located below the steel strip is the receiver, and the one above is the transmitter.
The SMI2.11.x signal processing unit supplies a sinusoidal AC voltage to the transmitter, adjusted according to its frequency and amplitude. A characteristic electromagnetic alternating field is formed at each transmitter coil and directed toward the opposing receiver. The receiver detects differences in the strength of the alternating magnetic field based on the strip position. Thus, the induced AC voltage provides an analog output signal for the strip edge position via variable amplitude levels.

The inductive measurement system includes comprehensive self-monitoring functions. Various signals are combined to summarize information as "Measurement device OK" and "Strip detected".
In addition to the certified "maintenance-free" and "stability" features, the new modular sensor design not only improves the symmetry characteristics of the SMI sensor series but also offers more accurate centering measurement precision and various options to meet your individual requirements.
Since it is resistant to disruptive external influences, even non-magnetic materials such as aluminum, copper, brass, and austenitic chromium-nickel steel (e.g., 1.4301) can be reliably detected by SMI sensors.

Customer Benefits:
Wide range of applications; measures strip thickness from 0.05mm to 16mm (other requirements available upon request)
The sensors are unaffected by the following factors:
Changes in insulation resistance due to dust accumulation on the measurement device
Interference from static fields, such as inspections by personnel
