MIK-WZPK RTD Temperature sensors with mineral insulated resistance thermometers

Category: Temperature
Views: 347
Description:

MIK-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.

Note
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℃.

	Class	Tolerance (℃)	Class	Tolerance (℃)
Pt100	A	±（0.15 +0.002\|t\|）	A	±（0.15 +0.002\|t\|）
( R(100℃)/R(0℃)=1.3851	B	±（0.3+0.005\|t\|）	B	±（0.3+0.005\|t\|）

Note．
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

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.
