Pneumatic Transmitter, Type 4080, ASME B 40.1 Grade 1A (±1.0% of span) Type 4480, ASME B 40.1 Grade 2A (±0.5% of span) BULLETIN TR-1 Providing plus-values which will coordi- nate 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 desig- nated operational check points by a sig- nal accurately transmitted with maximum efficiency, assuring operating economies and safety. The Ashcroft transmitter is a self-nulling motion-balance instrument, using a pneu- matic relay operating on the nonbleed force balance principle for converting input pressures into proportional low air pressure signals for transmittal to remote indicators or controllers.
