Type 3510 & Type 3520 Digital Enclosure Regulator
Brand: Marsh Bellofram Group of CompaniesMarsh Bellofram Type 3510 single and Type 3520 double loop electro-pneumatic servo pressure controllers combine the advantages of reliable solenoid valves and digital control, housed in a rugged, weatherproof enclosure.
Available with a local keypad programming option or RS-485 digital communications for PLC or PC control, these precision controllers allow the user the ability to set and extract data directly from the transducer with a PC or automation system, making for some of the most precise, accurate, and reliable devices available on the market. 
With a forward flow of 1.25 SCFM at 100 psi, Types 3510 and 3520 can be used alone for many applications or combined with a volume booster for flows in excess of 2,000 SCFM.
Various pressure output ranges are available from 29″ Hg vacuum to 600 psig. Standard accuracy is ±0.5% full scale or better. Enhanced accuracy version is ±0.25% full scale or better. A four-digit display of the output pressure is available with the keypad model.
