Moisture Probes

Accurate Moisture Measurement for Superior Industrial Production Quality

Moisture probes are essential components in mixing and processing systems, providing real-time and precise measurement of moisture content in raw materials. This ensures higher product quality, reduces material waste, and enhances process control throughout production.

These probes are engineered for heavy-duty industrial environments and designed for continuous measurement in applications such as concrete, food, ceramics, animal feed, glass, metal casting, and prefabricated building materials.

Working Principle & Connectivity

Moisture probes operate with a supply voltage of 24V DC ±10% and provide standard industrial output signals:

0–20mA
4–20mA

They can be connected directly to PLC systems or batching controllers without the need for additional signal converters or display units.

Types of Moisture Probes

Moisture probes are available in three main technologies to meet the requirements of different industries:

1. Capacitive Moisture Probes

These probes measure changes in the dielectric constant of the material.
They are suitable for granular and powdered materials with low to medium moisture levels.

2. Microwave Moisture Probes

These probes use electromagnetic waves to penetrate the material and analyze its response.
They are ideal for high-moisture materials and continuous mixing processes.

Additional Advantages:

Equipped with advanced microprocessor technology
Higher accuracy and faster response time
Supplied with user-friendly calibration and configuration software

3. HPR (High Frequency Polar Reflective) Moisture Probes

The latest and most advanced moisture-measurement technology.

Unlike capacitive and microwave sensors, HPR probes:

Analyze wave reflections inside the material
Detect the direct interaction of water molecules
Provide a more comprehensive and highly accurate moisture reading

Ideal for:

High-moisture materials
Non-homogeneous mixtures
Heat-sensitive materials
Applications requiring ultra-precise dosing and mixing

Applications

Moisture probes are widely used across several industrial sectors, including:

Ready-Mix Concrete Plants

Monitoring moisture of sand and aggregates
Optimizing mix ratios and reducing batch errors

Building Materials Production
