Type of Resistance thermometer sensor
|Nominal resistance value at℃||Class||Measuring current||R(100℃) / R(0℃)|
|1. R(100℃) is the resistance value of the sensing resistor at 100℃.|
|2. R(0℃) is the resistance value of the sensing resistor at 0℃.|

|1.Tolerance is defined as the maximum allowable deviation from the temperature vs resistance reference table．|
|2. l t l=modulus of temperature in degrees Celsius without regard to sign．|
|3. Accuracy class 1/n(DIN) refers to 1/n tolerance of class B in IEC 751|
-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℃.
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.
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
-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.
