    IS & NIS Junction Boxes?

    Hello, For the NIS signals in the hazardous area you should use Exe junction boxes. For IS signals Exe junction boxes could be used provided additional requirements as mentioned in IEC60079-11 is fulfilled. To avoid all the unnecessary burdens it is advisable to use IS certified junction boxes...

    Effect of Mass Flow Rate when using Orifice Plate

    Hi, Orifice will introduce additional pressure drop in the fluid flow. As a thumb rule you can assume pressure loss due to orifice will be approx. 0.2 bar. Now if your overall system pressure drop is much higher than this, then you won't notice any significant drop in flowrate. But if your...

    Ma to 0-10 Volt Conversion

    Hello, 4-20 mA over 500 ohm will give you 2-10V. I assume you are using a converter here which is converting this 2-10V into 0-10V. It seems to me you are getting only 3V because transmitter is not able to drive max. current through the 500 ohm resistance. If you can give us voltage...

    Single transmitter for two ESD outputs

    Thanks for your clarification. You have mentioned that it is not an uncommon practice. In which scenario it could be technically justified? If the transmitter PFD & HFT satisfies the SIL requirements for both the loops, is it allowed in compliance to IEC 61511?
