SENSOR OF TECHNOLOGICAL PROCESS PARAMETERS WITH POWER SUPPLY FROM CURRENT LOOP OF 4-20 mA

摘要

A sensor of technological process parameters with power supply from current loop of 4-20 mA comprises functional elements as well as a linear constant-voltage regulator and a current controller of 4-20 mA. The sensor functional elements and/or their groups of paralleled elements are series-connected by power supply, external terminals of formed branch are connected to the stabilizer output, an additional stabilizing device is introduced, which input terminals are connected to the stabilizer output and outputs are connected to internal connections of the branch of functional elements.
