Bulk Moisture Analyzer,SMART-MP





SMART series intelligent bulk moisture analyzer can be applied to measure the moisture content in most solids, which helps to control product quality and cost (dryer, water, energy, weight, etc.) according to material moisture.

Working Principle

The capacitance field sensor generates electromagnetic waves (frequency of about 30 MHz), which can penetrate about 15 cm inside the material. Because the change of the moisture content causes the change of the dielectric constant, which makes the electromagnetic field change, the moisture inside the material can be detected.

The NIR sensor emits near-infrared light of multiple wavelengths. The moisture content in the material has a certain proportional relationship with the amount of near-infrared light absorption of a specific wavelength, so it detects the moisture on the surface of the material and the shallow part of the material.

Typical application

★Food: grains, flour, soybeans, malt, rapeseed, corn, lentils, noodles, bean products, sugar, beet saccharification, beet flakes, candy, grain starch, coffee raw materials, food processing materials, fish meal, dry food, potato products , Potato flour, crumbs, flakes, seasoning powder, milk powder, spices, nuts, etc.

★Building materials: sand/gravel quartz powder, sand, bricks (raw materials), ceramics (raw materials), mortar, etc.

★Chemicals and pharmaceuticals: powder, granule, tablet, pill, flake fertilizer, phosphate, salt, potash, washing powder, polystyrene, foam plastic, synthetic material, PVC, acrylic paint, etc.

★Recycling: biomass, sludge, compost, etc.

★Others: wood shavings, sawdust, wood powder, calcium carbide slag, coal(pieces/powder), tobacco(shag/leaf), cast sand, glass, ceramics, coke, etc.


★It can store 6 calibration curves of different materials. When changing materials, directly replace the material curves without recalibration

★The capacitance field sensor can detect the average moisture inside the material

★Insensitive to the color and PH value of the material

★ Very high repeatability.

★High sensor protection level

★Maintenance-free sensor

★Optional high temperature (up to 130℃) sensor or explosion-proof sensor


All Smart series smart bulk moisture sensors are dustproof, waterproof, shockproof and knockproof, and optional explosion-proof. The most typical installation positions of the sensor are inside the silo, on the silo wall, on the material conveying ramp, the upper or lower part of the conveyor belt, on the screw conveyor, and mixers and dryers.
