Title: Electropneumatic positioner
Inventor: KIMURA ATSUSHI
IPC: F15B5/00
Filed: 1992-09-22
Abstract: PURPOSE:To transmit a high-reliable signal of valve opening without affecting any current signal by turning on/off the voltage generated in response to a current signal by a frequency signal proportional to a valve opening voltage. CONSTITUTION:A valve opening detecting means 32 uses the whole of or a part of the current signal to be transmitted from a controller through two transmission lines L1, L2 as the driving source and has a valve opening signal according to the valve opening of an adjusting valve generated. This valve opening signal is input into a frequency modulating means 35 and converted into the frequency signal according to it. A voltage overlapping means turns on/off the voltage related to the current to flow into an electropneumatic converting circuit 37 by the abovementioned frequency signal and overlaps the frequency modulation voltage on both ends of an input terminal in which the current signal is input. The frequency modulation voltage generated in the input terminal of an electropneumatic positioner 31 is detected as a voltage signal on the controller side connected to the electropneumatic positioner 31 through two transmission lines and demodulated as a voltage according to the valve opening of an adjusting valve.
