CONTROL IN THE FIELD WITH HART(R) COMMUNICATIONS

Typical capital budgets and more stringent demands on controlling the process require cost-effective field control. By providing digital sig naling and integrated PID capability, today's field instruments and HA RT protocol fulfil the requirements. Installation costs are substantia lly reduced using less hardware and digital communications to remote s ites. Control can now be applied to many applications which previously were not economical.
