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, a circuit, 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, 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 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.
A system for measuring a mixture ratio associated with a two-part fluid, at least one of the two parts of the fluid including conductive particles, the two parts to be mixed to make the two-part fluid, the concentrations of the two parts in the two-part fluid defining the mixture ratio, the system comprising:
A method of producing a two-part fluid, the method comprising:
A two-part fluid producing system, comprising:
