FIELD: measurement equipment.
SUBSTANCE: instrumentation includes measuring transducer (12), two-wire interface (34a, 34b), microprocessor (20), digital-to-analogue converter (22), the first control circuit (23a, 23b, 23c, 23d, 23e, 24, 26, 28, 30, 32) and the second control circuit (38). Current (IL) flowing through the two-wire interface indicates the state of measuring transducer (12). Microprocessor (20) is adjacent to measuring transducer (12). Digital-to-analogue converter (22) receives a signal from microprocessor (20) indicating the current value. The first control circuit (23a, 23b, 23c, 23d, 23e, 24, 26, 28, 30, 32) is connected to digital-to-analogue converter (22) and adapted for control of current value (IL) flowing through two-wire interface (34a, 34b). The second control circuit (38) is connected to digital-to-analogue converter (22) and supplies current to secondary load (50).
EFFECT: enlarging functional capabilities of the device.
