R750C 10-3000 PSIG Baratron® Absolute Capacitance Manometers with Trip Relays
R750C 10-3000 PSIG Baratron® Absolute Capacitance Manometers with Trip Relays
The R750C High-Pressure Baratron® Absolute Capacitance Transducer is a rugged, industrial-grade pressure and vacuum transducer with superior accuracy, repeatability, and long-term signal stability. It offers both a standard 0-10 VDC analog output signal and two (2) independently-adjusted electromechanical trip relays.
