Features:

  • Interface Between the Inductive Sensor Network and Strip Guiding System Backplane
  • Combines Capability of High-Precision Signal Processing with Redundant Sensor Support
  • Operates in Conjunction with the SMI Series and Standard EMG Strip Guiding Components
The EMG SMI2.11.3 operates as the Electronic Evaluation Unit in an EMG strip guiding system, providing reliable signal processing to all sensor modules within the network. It continuously processes incoming inductive sensor signals with high precision, ensuring accurate lateral position monitoring of metal strips and distributing this data through the system backplane to support real-time control of all guiding mechanisms. Seamless digital integration is standard with the EMG SMI2.11.3, featuring an integrated CAN-Bus communication interface that allows seamless data exchange within modern automated networks. The EMG SMI2.11.3 has made significant advancements in several areas over previous evaluation unit designs, incorporating sophisticated microprocessor-controlled compensation for varying material properties.

The EMG SMI2.11.3 provides essential evaluation functions common to the entire strip guiding system, and is a critical component of the sensing path, directly affecting the proper, accurate positioning of metal strips in high-speed processing lines. One or more EMG SMI2.11.3 evaluation units are required per system depending on the complexity of the processing line and desired redundancy level. The EMG SMI2.11.3 is designed for demanding industrial environments and is typically installed as a core component within the control cabinet of the strip guiding system.

For Dual Redundant Sensor applications, the EMG System can incorporate additional EMG SMI2.11.3 evaluation modules to ensure continuous operation. In addition to standard single sensor operation, the redundant configuration performs automatic signal validation. The EMG dual sensor configuration executes failover using the internal self-monitoring circuitry specified in the evaluation unit options. Using this method, the redundant sensing system continually monitors the health of both sensor channels. If the system detects that the primary sensor channel is no longer providing stable output (outside configured tolerance levels or due to cable breaks), it will automatically transfer the evaluation to the secondary channel and generate a diagnostic event in the System Event Log.

The SMI2.11.3 EMG Electronic Evaluation Unit may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
