Tempsens instruments offers fk series prts. These are robust and designed for large volume application where long term stability, inter-changeability and accuracy over a large temperature range are vital.
These thin-film rtd elements are of two types: type fk [-70ºc to 500ºc] and type fr [-70ºc to 500ºc].
A smaller dimension is also available and a high electrical insulation is guaranteed by non-conductive edges and sides. These elements are used in the automobile industry, domestic appliances, installation on pcbs, equipment and machinery, surface measurement, air conditioning, heating installation and control of primary parameters via temperature effects.
