EDS2-24A

SHEATH TYPE PLATINUM RESISTANCE THERMOMETER BULB DATA SHEET This resistance thermometer bulb is firmly sealed with highpurity oxidized magnesium (insulating material) in a fine metallic protective tube. Unlike ordinary resistance thermometer bulbs, it provides excellent sensitivity and vibration resistance, and is designed to permit easy bending work. FTH FEATURES 1. Resistance thermometer bulb is very small in size, providing excellent sensitivity. 2. Adoption of integrated structure has improved the vibration resisting characteristic. 3. Easy bending work allows fabricating a long-sized resistance thermometer bulb for easy measurement even in a place where ordinary type resistance thermometer bulb cannot be used. 4. Various types of terminals such as extension cable type, connector type, exposed type, terminal box type, etc., are also available for selection according to applications. 5. Measurement range covers –200 to +500˚C.
