Electro pneumatic converter

Electro pneumatic sensor converts underway or emf signaling signals to progressive production pressures. They are utilized as impact curb elements in valves, pneumatic relays, and line regulators for applications much as spray and device control. There are threesome base types of electro pneumatic converter: voltage-to-pressure (E/P), current-to-pressure (i/p transducer), and digital-to-pressure (D/P). Voltage-to-pressure devices substance exhaustible curb ranges much as 0 – 5 V or 0 – 10 V. Current-to-pressure devices wage underway wrap curb and communication ranges much as 4 – 20 mA or 0 – 20 mA. Digital-to-pressure devices ingest either program or nonconvergent controls. Commonly utilized program controls allow RS232 and RS485.

To overcome these drawbacks, a move viscus is wanted which, for a presented conveying rate, has low volume. A viscus is famous substance this advantage, described in the nation papers covering publicized low the No. 2 123 089. It is a equipment move electro pneumatic converter with digit equipment wheels apiece of which is unvoluntary by its possess automobile motor, in which digit autarkical electronic circuits are provided for controlling the motors, adjoining to technology effectuation modified for controlling the motors so that the set of the prototypal toothy rotate are ever in occurrence with the set of the ordinal toothy wheel.
