Cement Plant

"Cement Silo / Raw Mill Silo / Additives Hopper Overflow Protection & Dry Run Protection: Cement/Raw mill silos filled by bucket elevators and belt conveyors. To avoid over flow of cement silos and maintain minimum Level of the silo need to use precise level sensors for high and low level point level detection.

Our Tuning fork Level Switch (Model LSV) can be used for this application typical installation shown in above picture. LSV model also suitable for boot Level Sensing which protect the jamming of elevators due to excess level in the boot."

Cooler ESP Clinker Dust Level Sensing in Cement Plants

"Overflow, Underflow Protection.

Clinker Dust Level Measurement in cement plants poses following application challenges:

• High Process Temperature Max 600 °C
• High Ambient Temperature
• Low Di-electric constant of clinker and clinker dust
• Abrasion of probe caused by the material

For this challenges, Trumen offer following answers:

• SS wetted part with High alumina contain Ceramic insulation
• No Electronic part inside the sensor probe. Special PTFE insulated interconnection cable to connect sensor probe with electronic unit
• High sensitive microprocessor based electronic unit to sense low dielectric material
• High grade SS wetted parts for long durability"

Polyester Chips

"Under water chip detection in hot water:

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:

• High Temperature up 250 °C
• Solid Chips level detection under hot water
• Precise Switching under boiling water

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:

• Special designed high temperature sensor with cooling fins
• High resonance frequency with machine dynamic balanced fork tines not sense the liquid medium
• Microprocessor base electronic circuit design for fast and precise switching

Advantages of use of Level Sensors listed below:

• Sensor sense only solid chips, therefore ratio of water and chips can be maintained using Level Sensor
• Protection from over flow
• Reliable automation of production process

Fly Ash Level Detection in ESP Hoppers

" Overflow, Underflow protection.

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:

• High Process Temperature Max 250 ° C
• High Ambient Temperature
• Low Di-electric constant of Fly Ash
• Change in dielectric constant and wall build up due to moisture

Trumen has came up with elegant answers for the above application challenges such as:

• SS wetted part with Glass filled PTFE insulation
• No Electronic part inside the sensor probe. Special PTFE insulated interconnection cable to connect sensor probe with electronic unit
• High sensitive microprocessor based electronic unit to sense low dielectric material
• Buildup Compensated three element probe immune buildup
