What is a Level Sensor?

The Foundation of Liquid and Solid Level Control in Industrial Systems

In industrial production facilities, accurate level control in tanks, boilers, furnaces, and process systems is critically important for both safety and production continuity. Level sensors are automation components that control the system by detecting whether liquid or solid materials have reached a certain point. UK Teknik provides level sensor supply, installation, maintenance, and technical service for industrial furnace and process systems.

What is a Level Sensor?

A level sensor is a measurement and control device that detects the level of liquid, gas, or solid material within a tank or vessel.

Its primary functions include:

• Performing level control
• Preventing overflow and emptying risks
• Providing data to the automation system
• Ensuring safe process management

How Does a Level Sensor Work?

Level sensors can operate using various technologies. The general principle is to detect the material level and generate an electrical or pneumatic signal.

The operational process:

1. The sensor detects the medium.
2. It identifies changes in level.
3. It generates an electrical signal.
4. It sends information to the control system.
5. The system performs automatic control.

Level Sensor Failures and Symptoms

Problems can occur in sensors over time or due to environmental factors.

Incorrect Level Reading

• Sensor produces faulty data

Signal Interruption

• Information does not reach the control system

Contamination Problem

• Sensor surface gets covered

Mechanical Failure

• Float or moving parts get stuck

Importance of Level Sensor Maintenance

If regular maintenance is not performed:

• Incorrect level control occurs
• Risk of overflow or drying out increases
• System failures are experienced

With regular maintenance:

• Accurate measurement is ensured
• System safety is maintained
• Production continuity increases

During maintenance processes:

• Sensor cleaning
• Calibration check
• Connection check
• Signal testing

must be performed.
