RdF Corporation

About

RdF Corporation temperature sensors are integrated throughout critical systems on the world's most recognizable air and spacecraft.

Since 1955, RdF's high-reliability RTD's, Thermocouples, Heat Flux gauges and Heater elements have demonstrated high-accuracy capabilities from -423°F to over 2000°F. Those sensors are serving now in harsh environmental conditions from deep sea to deep space, and everywhere in between.

Our engineers provide solutions throughout design, qualification and production phases from our 35,000 sq. ft. manufacturing facility in Hudson, NH to clients worldwide.

RdF Corporation is a minority & woman owned small business.

Certified: ISO9001, AS9100, MIL-SPEC, ITAR Compliant

De-Icing & Windshield Elements

Transparencies & Structures

RdF’s resistance temperature sensors are integrated into the de-icing systems of commercial and military aircraft. Standard and custom components are incorporated into leading edge and rotor blade assemblies as well as various composite components use throughout the aircraft. Transparent wire-wound grids or point-sensitive RTDs are laminated into windshields and canopies with high optical clarity requirements. The stability and repeatability of RdF’s sensors mean consistent and reliable readings over the aircraft’s service life.
