In Polyester Oriented Yarn (POY) plant there a process to wash polyester chips. Hot water used for washing and the temperature inside the chips washing process tank is max 250 °C. Level Control for this process tanks are very important to avoid over flow and maintain the chips level inside the process tank.
Level sensing in POY application poses following challenges:
Trumen Vibrating Fork Point Level Sensor "LSV" model with high temperature sensor serve this application. As shown in application diagram our LSV sensor sense only solid polyester chips not water or foam inside the process tank.
These are special sensors devised with following attributes:
Advantages of use of Level Sensors listed below:
Fly ash detection in ESP hoppers is a very critical as well as tough application for level sensing switch.
Some of the mail application challenges are:
Trumen has came up with elegant answers for the above application challenges such as:
