Product catalog summary

Introduction to HART® Technology
HART® (Highway Addressable Remote Transducer) is a communication protocol developed in the late 1980s by Fisher Rosemount. It is widely used in the process industry for smart device communication, supported by over 100 manufacturers and integrated into more than 560 products.

Key Features of HART®

Allows simultaneous analogue and digital operation, using the 4/20mA analogue signal for control and the digital signal for additional data like device status and diagnostics.
Ensures backward compatibility with existing instrumentation, protecting investments in current systems.
Operates on a master-slave protocol with up to two masters per loop, typically a DCS or PLC as the primary master and a handheld configurator or PC as the secondary master.

MTL's HART® Solutions

MTL provides connections between HART® field instruments, control systems, and process automation management software, enhancing maintenance efficiency and reducing downtime.
The MTL4840 Series and 8000 Process I/O™ systems offer dedicated HART® connections for traditional and process I/O systems.

Instrument Management Software

MTL's HART® connections enable online access from a PC to HART® field devices, facilitating monitoring, configuration, calibration, and maintenance.
Software allows for regular status monitoring and integration of other fieldbus instruments into the system database.

HART® Communication Protocol

Uses Frequency Shift Keying (FSK) to superimpose digital signals onto analogue signal cables, allowing simultaneous communication without affecting the analogue signal.
Supports universal, common practice, and device-specific commands for consistent communication across devices.

Benefits of HART®

Provides valuable data for process operations, including device status, diagnostic alerts, and process variables.
Cost-effective communication solution that enhances plant operations and asset management.
Improves system integrity by providing continuous device status and diagnostic alerts.

Integration and Support

HART® technology is supported by the HART® Communication Foundation, which manages and enhances the technology to meet industry needs.
Offers a complete range of products and support for plant integration, including software, hardware, and training.
