WG 3.1 General Sensor Technology

Focus & Advantages

The NAMUR working group focuses on the standardization and quality assurance of field devices in the process industry. The documents reflect a systematic approach to harmonizing technical specifications in order to improve the interoperability, maintenance, and safety of automation components. The primary emphasis is on developing practice-oriented recommendations that benefit both manufacturers and users, while increasing efficiency in planning, procurement, and operations.

Key Focus Areas:

• Measurement Accuracy and Error Representation
  Uniform specification of measurement deviations and their documentation for better comparability
• Signal Standardization
  Harmonization of output signals, particularly for fault information (e.g., 4–20 mA standards)
• Software and Hardware Management
  Structured version labeling and change tracking for digital field devices
• Standard Device Parameters
  Definition of uniform device parameters with default values for faster commissioning
• Safety Requirements
  Integration of safety functions and diagnostic capabilities into standard devices for process safety instrumented systems (PLT safety devices)
