ARi is recognized as the industry leader of metal-sheathed, mineral insulated thermocouple cable. All our standard AerOpak® thermocouple cable is supplied with high-purity MgO (magnesium Oxide) insulation and accuracies per ASTM E-230 limits of error. We main larger inventories of finsihed cable and ARi also specializes in custom thermocouple, conductor and heatet cables to meet virtually any application requirement of temperature, environment or process conditions.

ARi uses that same high-quality cable to fabricate and manufacture in quantity our wide range of thermocouple, RTD (resistance temperature detector) and heater assemblies for myriad industrial and commerical uses. AerOpad® and Fan Type welded pad thermocouples are world-renowned for their quality and are used in power plants and in refinery operations for furnace heater tube measurements. Multi-point thermocouples and RTD's performance critical profiling of reactor and furnace temperatures. Our rugged-duty thermocouples and RTD's are used in aerospace applications, including engine and brake temperature measurements on commerical and military aircraft. ARi also supplies high-temperature thermocouples for applications up to 4000° F, using novel and refractory metals, for commercial heat treating and advanced laboratory/R&D applications.

ARi is a leading supplier of mineral-insulated heating assemblies and cable, as well. AerOrod® high-watt density heaters can supply up to 150 watts per square inch, yielding quick response and long use life in the most demanding applications. By using internally welded transitions between hot and cold sections, potential cold end failure is virtually eliminated. ARi heaters are used throughout the semiconductor manufacturing process, as well as in furnace element production, aerospace and heat tracing applications. Our reputation for custom solutions to the most demanding heater challenges is known worldwide, a face in which ARi takes great pride. Nonetheless, we are constantly exploring new technologies fo rheater thermodynamics and fabrications techniques, to meet the emerging markets we serve, every day at ARi. The forward-thinking philosophy benefits our customers and it remains our commitment to them.
