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) ÷

(Resistance span(Ω) × Sensing current(mA))
