The barrier can 82 is used to prevent leakage between the inner magnet assembly attached to a pump and the outer magnet assembly attached to a pump drive or motor. The barrier can is a non-metallic, composite barrier can composed of fiber and resin and includes a pole piece 88. The nonmetallic material and high strength configuration of the composite barrier can permits pump operation at high speeds and pressures with negligible eddy current generation. Using the composite barrier can results in minimizing heat developed in the coupling area and minimizing horsepower required from the motor. A resistance temperature detector 102 is operatively positioned on the exterior of or within the fiber layer 108 of the can such that the sensing portion of the detector is located proximate the closed end of the can. A method of manufacturing the barrier can is also disclosed.
