Smart Inductive Sensors Reduce Complexity And Cost In Legacy Automation Projects

Smart Inductive
Smart Inductive Smart Inductive

Summary

Industrial equipment designers implementing condition-based monitoring (CBM) in  legacy automation projects need to add additional functionality without significant reprogramming. Sensors with on-board decision-making and simple binary outputs for driving alarm or shut-down routines are essential. Rugged, multi-mode Smart Sensors from Contrinex trigger high-speed standard input/output (SIO) alarm signals, addressing existing routines on a central PLC without needing to disturb the legacy code.

Customer benefits 

  • Embeddable inductive Smart Sensors offer multiple sensing modes in a single device, allowing fit-for-fit replacement of existing devices
  • Cumulative data for condition-based maintenance, including temperature and operating-cycle count, is recorded in on-board data storage
  • The Smart Sensor’s dual-channel capability enables a high-speed binary SIO output to be triggered by an event-based exception
  • Existing alarm or shut-down routines are addressed directly by the SIO signal, without the need to disturb the legacy PLC code
  • Individual device configurations are stored locally, allowing plug-and-play replacement of sensors when needed
  • Industry-standard IO-Link connectivity provides a single interface to the machine control system for process data
  • Proven technology ensures highly reliable fit-and-forget operation with no manual intervention

Product specific advantages

  • Robust, metal-cased inductive Smart Sensors are ideal for easy integration
  • Multi-channel monitoring circuitry allows users to define multiple customized output thresholds
  • Sophisticated sensing electronics deliver high-precision multi-mode measurements
  • High-speed device-to-device communication enables decentralized data-processing and decision making
  • Smart Sensors are individually shielded and EMC immune, eliminating interference when multiple devices operate in close proximity
  • Dedicated service-data blocks hold device-specific data including product ID, location and serial number
  • Visible LED indicators enable sensors to self-identify on demand, simplifying commissioning and trouble-shooting routines
  • Industry-standard -25°C to +70°C operating range
