Title:
ADHESIVE MIX MONITOR
Document Type and Number:
WIPO Patent Application WO2006086041
Kind Code:
A9
Abstract:
A system for measuring a mixture ratio associated with a two-part fluid, at least one of the two parts including conductive particles. The system includes a pair of electrodes (126, 128), a circuit (112), and an output. The electrodes are disposed on opposite sides of the two-part fluid and sense the dielectric strength of the fluid. The circuit communicates with the electrodes to sense the dielectric strength and outputs a signal representing the dielectric strength. Preferably, the circuit includes a capacitive bridge (118), an input for a set-point, and an output for an error signal. Also, the system can include a housing for the electrodes. A timer (128) may also be provided to measure the time elapsed from the beginning of the mixing of the two-part fluid. Preferably, the two-part fluid is an adhesive with aluminum particles that is made from a resin and a hardener. Methods of producing two-part fluids are also provided.
