4.14.3 MATCHING A CURRENT TRANSDUCER

Use one resistor to develop the necessary voltage at the input:

R1 V OM-550 INPUT

TRANSDUCER

OUTPUT

Figure 4-9

V = OM-550 maximum input voltage

= 2.0000 VDC

= R1 * I

I = 1/2 transducer's maximum output current

R1 = 2 / I

The 4-20 mA Current Probe uses this technique (with R1=100 ΩΩ) to convert a 4-20 mA

current to a 0.4-2.0 VDC signal.
