double 4-20ma output

i have a sensor that produces 4-20ma signal. is there any way to obtain 2 output from one 4-20ma output. i think it can be done by opamps.
 

Re: double 4-20ma output

All what you need is a termination resistor of, say, 250Ω on the 4-20mA current loop.
This will generate voltage in the range of 1V(4mA input) to 5v(20mA). This voltage can be used to control two independent voltage-to-current converters which can be of sinking(to ground) or source(from the Vcc) type.
Examples of the voltage controlled current sources you will find here:
**broken link removed**
and another solution of sinking voltage controlled current generator is below (to have two outputs disconnect both collectors and treat the as individual current sources)

i found excellent product to obtain double 4-20ma output.
The product site is;
