ABSTRACT:
An inductive coil shaped screen traps debris in a fluid and senses the accumulation of the debris. The shaped screen coil comprises non-conductive wires parallel to one another and at least one conductive wire coil perpendicular and woven with the non-conductive wires. The conductive wire is a coil of an inductor. As debris accumulates within the coil, inductance immediately changes and indicates the accumulation of debris in the screen. Another coil connects with the first coil in a bridge circuit to compensate for changes in temperature of the fluid.
