摘要： Apparatus and method for momentary sampling of an atmosphere to determine electrostatic charge density. A nonconductive elongated sampling tube (12) is inserted into the area to be sampled. An intake valve (80, 96) on the end of the elongated sampling tube is opened momentarily and a small sample of the atmosphere to be sampled is moved through the intake valve and the elongated sampling tube into an isolated metallic inner cylinder (26) filled with metallic wool (30). An outer metallic cylinder (24) is located concentrically around the inner cylinder (26) and is electrically isolated therefrom except for a single discharge path through an electronic control package (16). Current flow between the inner cylinder and outer cylinder is measured by a sensitive ammeter (42) in the electronic control package and is electronically converted to indicate charge density in coulombs/meters3.

摘要： The invention provides an apparatus and method for monitoring the electrical conductivity of a web surface in which a forwardly moving web is exposed to an electrical field generated by a forwardly extending high voltage source so disposed adjacent the web as to induce a transverse redistribution of the electrical charges present on the web surface, the electrical field signal generated by the redistributed surface charges of opposite polarity to that of the source being monitored by a suitable field detector. Surface conductivity of a web may therefore be continuously and reliably monitored by a non-contacting technique, and the system is particularly suitable for controlling the level of antistatic behaviour induced in polymeric packaging films.

摘要： In a fiber quality sensor (S) comprising a first pair of electrodes, the first pair of electrodes include a first conductive electrode (1), and a first dielectric electrode (D, 2) having a first dielectric material (D) with a conductive backing (2). The fiber quality sensor (S) may further comprise a second pair of electrodes, the second pair of electrodes including a second conductive electrode (1), and a second dielectric electrode (D, 2) having a second dielectric material with a conductive backing, wherein in a tribo-electric series of materials, the material of the conductive electrode is arranged between the first and second dielectric materials. The fiber quality sensor (S) may comprise horizontally or vertically alternating first and second pairs of electrodes. The first and/or second pairs of electrodes may be tilted, slanted and/or zigzag-shaped. The fiber quality sensor (S) may for the or each pair of electrodes further comprise an amplifier coupled to the pair of electrodes and having an input impedance exceeding 1 T©, and preferably being 200 T©. The fiber quality sensor (S) is advantageously applied in a hair care device.
