  • Forum Post: Re: 4-20ma variable output driver

    Ian Williams Ian Williams
    Hello Greg, Thank you for your interest in a 4-20mA transmitter. We have a variety of parts available which can output any current within the 4-20mA range, so achieving 0.8mA increments will be no problem as long as the input signal is configured properly. The load of a 4-20mA transmitter is commonly...

    Ian Williams Ian Williams
    Hello Pierre, Have you considered the XTR111? It is a 4-20mA transmitter which generates a current output based on a voltage input, and it also has good stability vs. temperature. What is your application? What are you currently using to drive the OPA input? Are you using a 4-20mA receiver or some...

    Johnny amp Johnny amp
    I currently have a device that measures combustible gases using two filaments. one filament is coated with a catalyst. Basically both these resistor react to hotter gases / temperatures making more resistance. These sensors are designed to work with a: constant current of 0.125 Amps. Max voltage applied...

  • Forum Post: Current Limiting in 4-20mA loop

    Muhammad Rehan Muhammad Rehan
    Greetings, I am using a two wire 4-20mA current loop. Now I want to limit the input current to 2mA forcefully if any fault occurs in the system so that I could check if my supervisory circuitry is working fine or not. Please suggest me any circuitry or IC. Regards, Muhammad Rehan.
