Question

10) For the Rosemount 3051C Transmitter a) Would it fit into a 1ftx1ftx1ft box? b) Would it fit in a 6inx6inx6in box? c) What does a “starred” option represent? d) What are the various pressure ranges that can be selected. e) For isolating Diaphragms 2, 3, 4 and 7, what kind of materials can be handled by the sensor?

Answer 1

Referring to the above diagram, which clearly shows the dimensions

THE DIMENSIONS OF THE 3051C TRANSMITTER ARE = 4.1 INCHES, 8.2 INCHES, AND 6.4 INCHES

VOLUME OCCUPIED BY IT = (4.1X8.2X6.4) CUBIC INCHES = 215.168 CUBIC INCHES = 215 CUBIC INCHES ( ROUNDED OFF) = 0.1245 CUBIC FOOT

a) Since the volume of box, necessary to put the transmitter in must be greater than 0.1245 cubic foot, IT CAN EASILY FIT INTO 1FTx 1FT x 1FT box

b)Since the volume of box, necessary to put the transmitter in must be greater than 215 cubic inches, IT CAN EASILY FIT INTO 6 IN x 6 IN x 6 IN box?

c) "STARRED" option represent the most common options and should be selected for best delivery.
