Temperature Transmitters General Overview Analog (4 - 20 mA) transmitters provide a number of benefits for use in industrial sensing.The nature of current (versus voltage) loops is to maintain the proper current, even if there is significant electrical resistance in the line, up to its maximum voltage capability.For this reason, current-based control loops can be used over much greater distances (measured in miles versus feet). The 4 mA "live zero" provides a method to determine equipment failure, should the signal drop...
