The 4-20 mAmp signal converter is used to integrate the sensorProbe with a 4-20 mAmp transmitter. 4-20 mAmp technology is used to communicate analog signals over long distances where electrical interference is a problem. This solution is often used in the process control industry to collect the analog values from a wide array of remote sensors.
Current signals are much less susceptible to noise than voltage signals. A voltage signal can be converted to current and then broadcast over a long distance before it is converted back to voltage and read by the sensorProbe.
4-20 mAmp transmitters are common in the industry for use with high quality sensors. With the 4-20 mAmp converter these sensors can now be integrated into the sensorProbe enhancing their value with the addition of graphing, web interface, email interface, thresholds, and limits.
