Two-wire transmitter starter circuit and two-wire transmitter including the same |
摘要 |
<p>A two-wire transmitter starter circuit is configured to stably supply power at the time of start-up. The two-wire transmitter starter circuit includes a starter current generation circuit. The starter current generation circuit is connected in parallel with a current conversion unit configured to convert a detection signal of a sensor to a predetermined DC current. The starter current generation circuit includes a first series circuit where a first resistor and a shunt regulator are connected in series, and a second series circuit where a switching element and a second resistor are connected in series. The shunt regulator includes a first control terminal connected to a connection point of the switching element and the second resistor. The switching element includes a second control terminal connected to a connection point of the first resistor and the shunt regulator.
