Ashcroft 4080, 4480 Pneumatic Transmitter

Pneumatic Transmitter
4080, 4480

Providing plus-values which will coordinate key functional areas in your plant, this Ashcroft® pneumatic transmitter serves pressure applications throughout all industries. A positive report of process fluid and media performance is provided at designated operational check points by a signal accurately transmitted with maximum efficiency, assuring operating economies and safety.

The Ashcroft transmitter is a self-nulling motion- balance instrument, using a pneumatic relay operating on the non-bleed force balance principle for converting input pressures into proportional low air pressure signals for transmittal to remote indicators or controllers.
