R740D 20-3000 PSIG Baratron® Differential Capacitance Manometers with Trip Relays
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.
- 10 Torr (13 mbar) to 3000 PSI (204 bar) ranges with ±1% of reading accuracy
- 0-10 VDC analog output proportional to differential pressure
- Two independently-adjusted trip point relays
- All-welded Inconel® sensor construction allows for use with most corrosive media
- Self-contained sensor and signal conditioner in a compact and rugged enclosure
