Applications: SUP-WZPK RTD sensors is a mineral insulated resistance thermometers.Generally, electrical resistance of metal varies, depending on the temperature. Platinum in particular is more linear and has a larger temperature coefficient than most other metals. It is therefore, most suitable for temperature measurements. Platinum has excellent properties chemically and physically. Industrial high purity elements are readily obtained for long term use as a resistance element for temperature measurements. The characteristics are specified in JIS and other foreign standards; thus, it permits a highly accurate temperature measurement

Introduction



temperature sensor



Advantages


-A wide range of measurement

Due  to its very small outer diameter, this resistance thermometer sensor  can be inserted easily into any small measuring object. It is used over a  wide range of temperatures, from -200℃ to +500℃.


-Ouick response

This  resistance thermometer sensor has a small heat capacity due to its  smail size and is highly sensitive to small changes in temperature and  has a quick response.


-Simple installation

Its  flexible feature (bending radius more than double the sheath outer  diameter) makes for simple and on-the-spot installation into complex  configurations. The whole unit, except for the 70mm at the tip, can be  bent to fit.


-Long life span

Contrary  to conventional resistance thermometer sensors which have a  deterioration of resistance value with age or open circuits, etc.,  resistance thermometer sensor lead wires and resistance elements are  insulated with chemically stable magnesium oxide, thus assuring a very  long service life.


-Excellent mechanical strength, and vibration resistance.

High performance is assured even under unfavorable conditions such as when used in vibrating installations, or in corrosive

atmospheres.


-Custom sheath outer diameters available

Sheath outer diameters are available, between 0.8 and 12 mm.


-Custom long lengths available

Lengths are available up to 30 m maximum, depending on the outer diameter of the sheath.
