Cu INPUT
■ INPUT
• Sensing current (resistance span):
140 Ω ≤ Span ≤ 300 Ω : 1 mA
12 Ω ≤ Span < 140 Ω : 2 mA
8 Ω ≤ Span < 12 Ω : 3 mA
3.5 Ω ≤ Span < 8 Ω : 5 mA
• Max. leadwire resistance:
200 Ω or the value calculated using the equation below,
whichever is smaller.
Leadwire resistance(Ω) = (2500 - 100% resistance(Ω) ×
Sensing current(mA)) ÷ (3 × Sensing current(mA))
• Usable range:
3.5 Ω ≤ Resistance span(Ω) ≤ 300Ω
100 % resistance(Ω) ≤ (2500 – 3 × Leadwire resistance (Ω)
× Sensing current (mA)) ÷ Sensing current (mA)
■ PERFORMANCE
• Accuracy
Resistance span ≥ 20 Ω: ±0.2 %
Otherwise use the equation below:
Accuracy(%) = 0.02(Ω) ÷ Resistance span(Ω) × 100 +
0.1(%) × 40(mV) ÷ (Resistance span(Ω) × Sensing
current(mA))
• Temperature coefficient
Resistance span(Ω) × Sensing current(mA) ≥ 40(mV):
±0.015 %/°C
Otherwise use the equation below:
Temperature coefficient(%/°C) = 0.015(%/°C) × 40(mV) ÷
