An aluminum encased consists of an alloy metal coil-type resistance
element assembled into an aluminum enclosure. Following high-temperature
anodization, the enclosure is filled with a special non-flammable
cement paste and after hardening, insulation is applied through
a high-temperature process. Since the component is embedded
in the heat-proof cement, it is not affected by external mechanical
force, dusty environments, and extreme duty. It is durable,
vibration-proof, dissipates heat well, and has a low temperature
coefficient, with resistance varying in direct proportion. Supporting
a flexible range of applications, the product is easy to utilize
and install. Applications include industrial machinery, load
testing, electric power distribution, instruments, and automated
control installations. | Performance Specifications |
