• Advantages

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.
