Microwave Moisture Analyser Measurement advantages Vs near Infrared Technology |
||
| Potential Limitation | MOISTSCAN ® | Near Infrared |
| Vertical segregation | Unaffected - beam penetrates full bed of material | Reflectance technique from surface molecules only. |
| Sample presentation | Unaffected by position of material | Distance of material surface to receiver important |
| Colour | Unaffected | Significant effect |
| Ambient lighting | Unaffected | Requires shielding |
| Wear | No moving parts | Mechanical filter system |
| Presence of steam | Unaffected | Can cause interference |
| Dirty Atmosphere | IP65 enclosures | Window requires to be kept clean |
|
Microwave Moisture Analyser Measurement advantages Vs Capacitance |
||
| Potential Limitation | MOISTSCAN ® | Capacitance |
| Vertical segregation | Unaffected - beam penetrates full bed of material | Very limited material penetration, possible vertical segregation effects |
| Sample presentation | Unaffected by position of material | requires control of distance of conveyor belt to system |
| Conductivity of Material | Wide range of materials amenable to technique | Limited range of applications |
| Steel cored reinforced conveyor belts | Can be used | Cannot be used |
