2-Wire Flow Transmitter In A Single Package


	See Larger View

Economical single package solution includes sensor and transmitter:

Differential Pressure measuring principle avoids problems associated with sticking floats and plugging passages.

Solid state strain gauge senses differential pressure directly.

Low maintenance design with no moving parts.

Designed for use with computer control systems or remote readouts.

Signal is proportional to flow rate squared (r²). (Square root extraction is required in the receiving device.)

Intrinsic safety option for Class I Div. I, Groups A,B,C,D; Class II Div 1, Groups E,F,G; EExia IIc T4 (CSA and Cenelec approvals pending).
