EDS2-24A Datasheet, PDF (1/2 Pages) Fuji Electric – SHEATH TYPE PLATINUM RESISTANCE THERMOMETER BULB

SHEATH TYPE PLATINUM RESISTANCE THERMOMETER BULB
DATA SHEET
This resistance thermometer bulb is firmly sealed with high-
purity oxidized magnesium (insulating material) in a fine me-
tallic protective tube. Unlike ordinary resistance thermom-
eter bulbs, it provides excellent sensitivity and vibration re-
sistance, and is designed to permit easy bending work.
FEATURES
1. Resistance thermometer bulb is very small in size, provid-
ing excellent sensitivity.
2. Adoption of integrated structure has improved the vibra-
tion resisting characteristic.
3. Easy bending work allows fabricating a long-sized resis-
tance 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.
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 ex-
pressed in (˚C) independent of +/–
symbols.
2) Allowable error is the maximum
limit of resistance value of resis-
tance thermometer bulb obtained
by subtracting measured tempera-
ture from the temperature calcu-
lated according to the reference
resistance table.
