4080/4480 Pneumatic Transmitter
Brand: Ashcroft IncDoes not ship to OH, United States
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.
