HART communicator features and connection

A HART communicator is a portable device, based on HART communication protocol. A HART communicator works as a secondary master in a control loop. A field communicator supports both HART and Foundation Fieldbus devices. HART communicator devices are used to check variables online and for calibration purposes. The communicator is portable, thus wireless runs in …

Basics of wirelessHART network protocol

The WirelessHART™ standard provides a robust wireless protocol for the full range of process measurement, control, and asset management applications. It adds wireless capabilities to the HART Protocol while maintaining compatibility with existing HART devices, commands, and tools. A wirelessHART device uses nominal 2.4GHz transmission frequency using IEEE 802.15.4 standard radios because meeting these criteria allows WirelessHART …

Basics of Hart Communicator

Introduction HART is a master-slave communication protocol  , which means that during normal operation, each  slave (field device) communication is initiated by a master  communication device. Two masters can connect to each HART loop. The primary master is generally a distributed control system (DCS), programmable logic controller (PLC), or a personal computer (PC). The secondary master can be a handheld terminal or another PC. Slave devices include transmitters, …

How to find out the Full load current [Relation between horse power and kilo watt] and how to select a proper cable [Power cable size selection chart]

In previous posts i have explained about electrical drawings, electrical panel component etc.. For smooth working of motor which is connected to the mcc panel, cable size selection has an important role. We have to consider lot of things for selecting a proper cable, like motor rating (Kilowatt,Horse power),Voltage(230v, 415 v etc.),Phase(Single, 3 phase),Temperature, Distance …
