I am not sure what you are asking? When you say "Can we use 4-20mA Current Receiver" are you saying you want to read a 4 - 20 mA current loop and display the results in an engineering unit? For example you have a sensor with a 4 - 20 mA output and you want to read that signal using a RS 232 port or USB port? Should that be the case then to what uncertainty or accuracy? Most current loop measuring devices, like those listed by bruce429 simply convert the current to a voltage and measure the voltage using an ADC (Analog to Digital) converter.Can we use 4-20mA Current Receiver with RS232 or USB if yes which one is more efficient ???
Hey DanaYou would have to build an interface to translate the protocol, basically
a UP running SW that translates the 4/20 ma loop to/from the RS232 or
As far as efficiency, what are you asking, parts count, power, protocol information
density, speed ......?

Hi Bruceit depends on your application. If you are trying to use it with a modern PC then you might wanna go with a USB because new PC doesn't have RS232.
There are so many ways to build a USB 4-20mA receiver device.
Here are some devices you can use
HiYou simply repeated the same request as in post #1 with no new information.
What is a 4-20mA current Receiver?
We know 4-20mA is current. What does the Receiver do?
What are you trying to measure or what information are you trying to transfer to the PC?
Give us a make and model number of the device.
DATAQ Instruments offers a wide range of starter kits and another offering is from Measurement Computing as to interface modules. A simple Google of Data Acquisition should bring up a few dozen hits. I can not tell you what you want or need as it grows apparent you don't know what you want or need and can't define the project.Arduino Uno is a microcontroller board based on the ATmega328P (datasheet). It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz quartz crystal, a USB connection, a power jack, an ICSP header and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started.. You can tinker with your UNO without worring too much about doing something wrong, worst case scenario you can replace the chip for a few dollars and start over again.
No i am not same personStill no new information.
What is the sensor?
What software are you going to use on the PC?
How are you related to Karzo94? Are you the same person or two persons on the same project team?
