Teflon

As an integral part of any high accuracy thermocouple temperature measuring system, the wire is subject to severe conditions and quite often rough handling from operatives. Repeated bending, or cold working of a thermocouple can generate stress and distortion of the crystalline structure of the wire, resulting in significant potential for measurement error. Withnell sensors thermocouple wire is multi stranded, made of the highest purity and uniformity available, to minimise measurement error from cold working and material inconsistencies.

Withnell Sensors premium Type 'T' thermocouple wire is available in 3 and 7 strand configurations, individually insulated with an optional overall clear Teflon insulation. The three stand wire is used where space is at a premium or where the wire must be fed through narrow openings like down plastic tubing or in a small filter housing. The three strand wire has a major OD of 1.88mm and can be used in most processes from Liquid Nitrogen (-196ºC) up to a continuous temperature of 200ºC. The seven strand wire has an OD of 3.05mm and is used where extra strength is needed.
