RESIOPAK is the trade mark for our metal sheathed mineral insulated resistance thermometer sensors. It is so constructed that conductors and temperature elements (CERACOIL) are surrounded by inorganic insulation (MgO) within a stainless steel or heat resisting steel sheath. Using this RESIOPAK, a wide variety of applications are available. Compared with general-purpose (protection tube type) resistance thermometer sensors, this mineral insulated resistance thermometer sensor offers many advantages.
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
This resistance temperature sensor RESIOPAK has the following advantages over conventional ones
1. 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 -200좧 to +500좧.
2. 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
3. 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
4. Long life span
Contrary to conventional resistance thermometer sensors which have a deterioration of resistance value with age or open circuits, etc., RESIOPAK resistance thermometer sensor lead wires and resistance elements are insulated with chemically stable magnesium oxide, thus assuring a very long service life.
5. 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.
6. Custom sheath outer diameters available
Sheath outer diameters are available, between 0.8 and 12.75 mm.
7. Custom long lengths available. Lengths are available up to 300m maximum, depending on the outer diameter of the sheath
8. Compatible with special needs
Small sheath outer diameter and flexibility save installation space, thereby making it possible to install the detector with minimum flow obstruction. A variety of sheath outer diameters allow a suitable choice for a wide range of applications. A sensor with 2 elements (6 conductors) is also available.
