Radiometric Level Sensor

TECHNICAL SPECIFICATIONS OF RADIOMETRIC LEVEL SENSOR

How Does a Radiometric Level Sensor Work?

A radiometric level sensor measures the amount of radiation passing through a vessel. A radiation source is placed on one side of the vessel and a detector is placed on the other. As the level inside the vessel changes, the amount of radiation reaching the detector changes too. The system then converts this change into a level signal. Since the measurement is taken from outside the vessel, the sensor does not come into direct contact with the product.

Why Use a Radiometric Level Sensor?

Radiometric measurement is often the preferred choice when other level instruments may not perform reliably. It is a practical solution for demanding processes involving:

• High temperatures
• High pressure
• Dust or vapour.
• Corrosive or abrasive materials
• Toxic process media.
• Complex vessel design

It is also suitable for various measurement tasks, including point level detection, continuous level measurement, interface measurement, and density measurement.

Where Is a Radiometric Level Sensor Used?

Radiometric level sensors are commonly used in industrial vessels and process units where non-contact measurement is required. Typical applications include:

• Reactors
• Autoclaves
• Separators
• Acid tanks
• Cyclones
• Silos
• Tanks
• Pipelines

These sensors are ideal for harsh process environments where direct contact measurement is difficult or impractical.

Which Materials Can Be Measured by the Radiometric Level Sensor?

Radiometric level sensors can be used with:

• liquids
• Solids
• suspensions
• slurries

This makes them a flexible option for many industries, particularly where difficult process conditions require one measurement principle to be used.

What Can a Radiometric Level Sensor Measure?

Depending on the application, a radiometric level sensor can be used for:

• Point level detection
• Continuous level measurement
• Interface measurement
• Density measurement

This wide measurement range makes radiometric technology useful in many different process control and monitoring applications.

What Are the Main Advantages of the Radiometric Level Sensor?

Radiometric level sensors provide reliable, non-contact measurement in challenging process conditions where conventional sensors may not perform effectively.

Non-Contact Measurement

The system measures from outside the vessel, meaning it does not come into contact with the material. This makes it ideal for aggressive, abrasive or hazardous products.

Reliable in Extreme Conditions

Radiometric measurement is ideal for harsh process conditions, such as corrosion, abrasion, viscosity and toxicity. It is also used in processes involving extremely high temperatures and pressures.

Suitable for Difficult Vessels

It is an excellent choice for reactors, autoclaves, separators, acid tanks and cyclones, where the design of the vessel or the operating conditions can make other technologies more difficult to use.

Flexible Measurement Applications

The same technology can support point level, continuous level, interface, and density measurement. That gives more flexibility in plant design and operation.

Designed for Functional Safety

The system is designed according to IEC 61508 and approved for SIL2/3, making it suitable for demanding safety-related measurement tasks.

Less Verification Effort

With Heartbeat Technology, verification becomes easier and plant shutdowns can be kept to a minimum.

High Ambient Temperature Resistance

Its innovative sensor technology allows use in ambient temperatures up to +80°C (+176°F) without additional cooling.

Remote Operation with Bluetooth

Bluetooth® wireless technology allows remote access and operation outside the radiation beam area.

When Is a Radiometric Level Sensor the Right Choice?

A radiometric level sensor is usually the right choice when:

• The process is too hot or too pressurized for contact sensors
• The product is corrosive, abrasive, or toxic
• Dust, vapor, or difficult vessel geometry affect other technologies
• The vessel cannot be opened easily
• Reliable non-contact measurement is needed over time

In these cases, radiometric measurement can offer stable performance and dependable process monitoring.

What Should Be Considered Before Installation?

Radiometric systems use a radioactive source, so installation and operation must follow strict safety rules and local regulations. Proper shielding, installation, maintenance, and approved handling procedures are important parts of the application.
