R740D 20-3000 PSIG Baratron® Differential Capacitance Manometers with Trip Relays
Model: R740D
Overview
Overview
The R740D High-Pressure Baratron® Gauge Capacitance Transducer is a rugged, industrial-grade pressure and vacuum transducer with superior accuracy, repeatability, and long-term signal stability. It has a standard 0-10 VDC analog output signal and two (2) independently-adjusted electromechanical trip relays that can be used to switch external components such as pumps, valves, and other equipment. The electronics are mounted in a rugged stainless steel housing designed for heavy industrial use. The R740D is referenced to atmospheric pressure, offering full-scale measurements from 20 to 3000 PSIG (1.4 to 204 bar).
