Surface RTDs
RdF’s tough surface RTDs optimized for user installation are presented in this section. Exclusive designs outperform all others for installed accuracy, environmental resistance and easy installation. Contact us for installation recommendations including optional adhesive layers

Stikon® RTD _

Stikon® RTD    (See Surface Capsules for miniature choices)
This platinum wire sensor proven over 4 decades is thin, flat and flexible to sample the temperature uniformly over the attached area. Large 3 or 4 wire flat cable leads are strongly anchored in the sensor.

Strapon® Surface RTD sensor _ Strapon® RTD    (See Immersible Capsules for plain surface sensors)
Everything needed for successful industrial surface temperature measurement on flat or curved surfaces down to 1" radius. The stainless steel sensing surface and thermal insulation over the sensor flex for good contact, in three attachment configurations. Safe for condensing environments.
