TEMPERATURE CONTROL TRAINER

PRODUCT DETAILS

Description

The setup consists of heating tank fitted with Thyristorcontrolledheater for on line heating of the water. Wateris supplied from laboratory constant head tank and itsflow can be manipulated and measured by provided Rotameter. The temperature of the heated water issensed by RTD sensor. This measured variable through Temperature Transmitter is communicated to Digital Indicating Controller. Error is calculated and outputaccordingly, is communicated to Thyristor Controlledheater to achieve the Set Point. These units along withnecessary piping are supported in a well-designedhousing and are fixed on base plate.The present set-up is completely computerizedcontrolled. The Digital Indicating Controller have a facilityto interface the system with computer which enables tochange the PID parameters using computer. Theeducational software and data-logging package has beendeveloped for unit. The software environment base is of Labview of NATIONAL INSTRUMENTS, USA. This softwareis compatible to interfacing unit. This software package provides acomprehensive educational software environment within which the PID investigations can be performed. Thissoftware is capable to tabulate the sample readingsaccording to the requirement of experiment under studyand results obtained can be compared. The real time dataacquisition can be done by interfacing the set-up withcomputer using software. This software can be usedoutside the laboratory with the computer to familiarizethe students with the equipment and procedures withthe help of Flow Diagrams provided in the software. Inflow diagrams Set Point, Process Variable and Controllers Output are visible on the screen and this data can betransferred in Excel Files for further calculations, plottinggraphs etc. Software allows the user to have control onsampling time, data logging, printing the stored data,preparing spread sheets in Excel etc.
