Type A201 electro-pneumatic intersystem transmitter is used for conversion the standard analogue electric signal on standard pneumatic signal at range 20...kPa or 60..300 kPa in automatic regulation systems or control industry systems. This transmitter posseses cooperation the electronic automation systems with executive elements.
The transmitter's working is based on comparison moment rule of force made by coil which was put in constant magnetic field proportional for input signal, with moment of force made by metalic pressure capsule of feedback, where the pneumatic output signals supplied. Change of direct of transmitter working ("diectly" or "inversely" working) might be realized by change current flow direction by coil and correction of transmitter redulation.
