Understanding 4-20mA Data Accuracy In Particle Counting

When considering using a 4-20mA particle counter you should verify how this can affect the number of particles that are displayed on your software. Measurement resolution can have an impact on the accuracy of the values of particle counts being seen based upon the analog-todigital conversion process of the device.

Should you use a Modbus (digital protocol) sensor instead of a 4-20mA sensor? That question can only be answered by understanding the difference between an analog (4-20mA) signal and a digital signal such as Modbus.
