Sensors for Tapio Analyzer

The available sensors for the Tapio Analyzer can be found below.

Basis Weight Sensor

Beta radiation basis weight sensor
Kr-85 source with semiconductor detectors
Aperture 5 mm
All grades up to 1000 g/m^2, accurate basis weight measurement up to 10 000 samples/m
Wet end, stock approach, coating problem solutions
Formation measurements, flock size analysis
Verification and calibration of online measurements

Caliper Sensor

Small contact area, d=0.3 mm
Range up to 800 μm, can be extended
High accuracy caliper profile
Calender, press section problems
Printability estimation
Verification and calibration of online caliper measurements

Gloss Sensor

Dual-sided measurement of standard gloss & small scale gloss variation
Standard angle 75°
Aperture 5 mm
All grades, even base paper
Press section, rolls, felts
Coating, backing roll effect verification and identification, size press effects and other
Small scale gloss variation before and after printing (i.e. gloss mottling studies)
Verification and calibration of online measurements
Ideal for paper machine troubleshooting

Ash Sensor

Transmission Sensor

1 mm aperture
All grades, wavelength selectable white / red / IR
Press section variations, moisture and temperature related variations
Optical formation and flock size analysis
In most grades transmission has good correlation to basis weight
Important when calender, press section and wet end effects must be separated from each other

Remission / Brightness Sensor

0.3 mm aperture
Brightness variation of paper
All grades
Correlates with coating variations
Calender blackening studies
White top board (see-through variation)

Porosity Sensor
