Learning System: T5552-H1

Amatrol’s Hart Process Control 1 Learning System (T5552-H1) adds to the Level and Flow Process Control Troubleshooting training system (T5552F) to teach one of the most commonly-used communication protocols. The HART (Highway Addressable Remote Transducer) communications training protocol is a powerful technology that has widespread use because it has backward compatibility that lets smart sensors digitally communicate on existing 4-20 mA control wires without harming analog signals.

Using the T5552-H1, learners will practice valuable hands-on skills, such as configuring and installing a HART interface; using a HART field device to verify the integrity of a process control loop; and measuring flow and calibrating a differential pressure flow transmitter using HART software. Using Amatrol's eLearning curriculum, learners will study the theoretical aspects of HART and then follow along with step-by-step explanations of hands-on skills. Topics include HART networks, existing system integration, and calibrating HART devices and monitoring current loops.

What is HART Technology and Why is it Important?

Analog sensors have long been used to send simple process values back to a controller. For example, a current in the range of 4 to 20 mA could represent pressure values from 0 to 100 kPa. However, with the invention of smart sensors that contain microcontrollers, it became possible to send digital data along with the analog signal. With HART protocol technology, the analog data and the digital data can all be transmitted simultaneously by piggybacking the digital data onto the analog signal. HART technology uses the wires already present for the analog signal to transmit digital data to control devices.

Hands-On HART Communication Protocol Skills

A HART device’s smart sensor can transmit an analog signal to a PID controller that represents a process variable, such as fluid level. At the same time, it can digitally transmit the setpoint percentage, temperature, volume, and more. Although HART technology allows for bi-directional communication, its primary function is sending data from sensors to the controller, not from the controller to the sensors. Therefore, HART technology is rarely used to control devices.

In-Depth eLearning Curriculum

Amatrol's HART Process Control training system features interactive eLearning curriculum that integrates various types of learning methods to create an engaging, effective learning experience. Amatrol’s multimedia eLearning curriculum includes text with voiceovers, videos, 3D animations, pictures, and interactive activities, quizzes, and self-reviews. Specific HART communication protocol topics covered include: identifying the components of a HART process control system; configuring a HART modem; measuring flow and manually calibrating a differential pressure transmitter; and calibrating a differential pressure transmitter using HART software.

Free Learning Management System (LMS)

Amatrol eLearning is easy-to-use for both students and instructors. Its web-based interface is simple to navigate and available on any WebGL-compatible Internet browser. Instructors love Amatrol eLearning for its simple, yet sophisticated Learning Management System (LMS). The LMS allows instructors to create custom courses, monitor student participation, track course progress, assess knowledge levels prior to a course, and test knowledge levels after completion. Learners appreciate the fact that they can start and stop as needed, moving through each Amatrol course at their own pace. If a self-review reveals that they didn’t understand a particular topic as well as they thought they did, they can revisit it before moving on.
