HART - proven for process automation

Get more from your HART devices by employing us as your project partner.

HART is an industrial standard with a very large installed base worldwide. It is a “smart” technology, i.e. it supports the simultaneous transmission of a 4...20 mA analog signal and digital communication over the same pair of wires.
In almost all applications the HART signal is used for parameterization only. With the appropriate tools, however, HART puts continuous device monitoring, real-time device diagnostics and multi-variable process information for new and old devices within your grasp.

Your HART benefits

Exploit the potential of HART with us as your partner:

  • Over 20 years experience with a proven technology

  • Comprehensive range of HART measuring instruments

  • Advanced diagnostics and intelligent multivariable devices

  • Simple commissioning and device management

  • Simple integration into control systems

  • Auxiliary hardware and handheld

  • Worldwide service and support

Device integration

There are three basic ways of integrating the measurements provided by HART devices into a control system:

  • Point-to-point connection of the 4...20 mA signal

  • Connection via a remote I/O or HART multiplexer to a superordinated bus system, e.g. PROFIBUS

  • On rare occasions, connection of a HART multidrop bus to a HART I/O card

Only in the two latter cases is the full device information available to the control system.

Device operation and management

HART device information (parameters, status etc.) can be accessed by:

  • An FDT frame, e.g. FieldCare, which requires a so-called DTM for each device type

  • A DD/EDD operating tool such as Field Xpert SFX350/SFX370 handheld, Asset Management Solution (AMS) and Process Device Manager (PDM)

We offer DTMs, DDs and EDDs for all our HART devices and ensure they are integrated into the above-mentioned tools.

Device drivers and certificates

The device description files and certificates can be obtained from the download area of each product.

Are you a HART user?

Do you:

  • have an extensive HART installed base and want to stay with the technology?

  • want to commission and operate your HART devices more effectively?

  • want to integrate your HART devices into a plant asset management system?

  • simply want the benefits of reliable, best-of-class HART instrumentation?

For HART users, we provide not only a full portfolio of HART instruments, but also HART solutions that will help you to operate your plant more efficiently.
