Zusammenfassung:	The present invention relates to a device, system and method to measure tackiness of a substance, such as pulp, with an on-line or an in-line sensor having a transparent plate with a surface where tacky particles can attach. Attached particles are identified by a camera behind the plate. The camera is focused to detect stationary particles attached to the surface. Measurement is performed directly from a process stream or from a sidesteam and the plate does not need to be removed from the process for the measurement. The plate material may be plastic, such as polycarbonate or acrylic. Additionally, the flow speed may be kept be low, e.g.
