The benefits of two-wire instrumentation

Because sometimes, less is more!

The benefits of two-wire instrumentation

As the complexity of measurement technology steadily increases in terms of number of applications and devices available from a wealth of manufacturers, so too does the call for some degree of uniformity and consistency in field instrumentation. Couple this with the demand for improved operational reliability and plant availability. Our two-wire device concept offers a cost-effective, simple and reliable solution to the requirements of instrument users.

  • The benefits of two-wire instrumentation ©Endress+Hauser

    Standardised two-wire concept for flow and level increases safety and reliability and reduces costs.


  • Intuitive, standardised operation: reduces complexity and the costs for training, commissioning, maintenance and operation. Automatic data back-up allows easy replacement of electronics without recalibration.

  • Modular concept for spare parts and components: reduces storage costs and increases system availability through interchangeable components.

  • Seamless system integration: reduces engineering overheads and harmonizes software version management to ensure stable system operation.

  • Uniform hazardous area concept: allows maximum security with maximum flexibility in global use. The consistent implementation of the relevant industry standards ensures high reliability.

  • Fast decision support in case of failure (according to NE 107): avoids or reduces plant shutdowns.
