FUJI EDS2-24A

SHEATH TYPE PLATINUM RESISTANCE THERMOMETER BULB
DATA SHEET
FTH
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.
FEATURES
SPECIFICATIONS
• Applied standard:
JIS C 1604 -1997
• Resistance element:
Nominal resistance; Pt100
Class; A, B
Rated current; 2mA
Allowable error due to temperature;
Class
Allowable error
A
±(0.15+0.002t)˚C
B
±(0.3+0.005t)˚C
Note:1) "t" is measured temperature expressed in (˚C) independent of +/–
symbols.
2) Allowable error is the maximum
limit of resistance value of resistance thermometer bulb obtained
by subtracting measured temperature from the temperature calculated according to the reference
resistance table.

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.
