R85 Series Mini Transducer

Brand: ASCO
The R85 Series I/P, E/P transducers are a series of compact electronic pressure regulators that convert an electrical signal (current or voltage) to a proportional pneumatic output.

Utilizing internal solid-state feedback circuitry, the R85 provides precise, stable pressure outputs to final control elements. Immunity to the effects of vibration or mounting position, high tolerance to impure air, and low air consumption make this unit ideal for use in demanding applications.

The heart of this unique technology is a bimorph piezo actuator that is encapsulated in a protective skin. This protective skin provides defense against the humidity and contaminant often found in process operating environments.
Features
  • Reliable in harsh environments
  • Low air consumption - 3 SCFH typical
  • High accuracy - +/-0.10% of span
  • NEMA-4X (IP65) enclosure
  • Vibration/position insensitive
  • Compact size
  • Wall, panel (included), pipe (included), or din rail mounting
  • Supply pressures up to 100 PSIG
  • Built-in volume booster - 10 SCFM flow
  • Input/output ports on front and back
  • Conduit fitting or din connector
  • Split range operation
  • Field reversible
  • CE Approved
