Product Overview

AL-E850 LEVEL CONTROL TRAINER


Discription:

Description

 

Level control trainer is designed for understanding the basic principles of level control. The process setup consists of supply water tank fitted with pump for water circulation. The level transmitter used for level sensing is fitted on transparent process tank. The process parameter (level) is controlled by microprocessor based digital indicating controller which manipulates pneumatic control valve through I/P converter. A pneumatic control valve adjusts the water flow in to the tank. These units along with necessary piping are fitted on support housing designed for tabletop mounting.

The controller can be connected to computer

through ethernet port for monitoring the process in SCADA mode. Product is supplied with 32 tag demo
