The new Impulse Series guided-wave-radar level transmitter employs field proven Time Domain Reflectometry (TDR) technology to provide accurate measurement of total level, distance or volumetric outputs. TDR technology has been widely used in level measurement because of its inherent ability to remain unaffected by variations in process materials’ electrical characteristics. The 3-mm Impulse Series transmitter provides continuous level measurement of liquids to ranges up to 50 ft (15 m), with a two-wire 4–20-mA, HART output signal. It has five different sensor types and is constructed of 316 stainless steel and Hastelloy C for use in environments that are classified as hazardous (Class I, Div. 1) with either intrinsically safe or explosion-proof installation requirements. — Ametek Drexelbrook, Horsham, Pa.
