Transducer, Electro-Pneumatic, Type I/P, 0-100 psi, 4-20mA, TTL Logic Output

The Type 3211 single loop and 3221 double loop electro-pneumatic servo pressure controllers incorporate two solenoid valves and an internal pressure sensor for increased sensitivity and accuracy. With current or voltage signal inputs, the Type 3211/3221 controls an output pressure with an accuracy of ± .5% or better full scale. A wide range of output pressures available, from 29 Hg vacuum to 600 psig. With a flow of 15 SCFM at 100 psi, the 3211/3221 can be used alone or in conjunction with a volume booster to achieve flow rates in excess of 2,000 SCFM. The double loop 3221 option permits 0-10 VDC feedback from a remote sensor.
