The BetaGauge 311 Pressure Calibrator provides unmatched pressure measurement flexibility over any competitive unit, setting a new standard over the venerable BetaGauge 320. The BetaGauge 311 provides 0.025% FS accuracy on both internal, isolated, stainless steel pressure sensors. An external pressure module connection supports all BetaPort-P pressure modules for even greater measurement capability. A Pt100 RTD input is provided for temperature measurements accurate to 0.1 C (0.2 F). In addition, the BetaGauge 311 measures 4-20 mA loop current and up to 30 VDC. An internal 24 V Loop Power Supply can power a transmitter under test. The BetaGauge 311 supports up to three simultaneous measurements in any combination, including three pressure measurements. With simultaneous display of two pressure and an RTD temperature measurement, the BetaGauge 321 is ideal for gas flow calibration(custody transfer) applications. The BetaGauge 311 is available in many ranges from 10" water up to 10,000 psig. Compound and Absolute (PSIA) ranges are also available. It is also available in a Kit, which includes the BetaGauge 311 Pressure Calibrator, Pt100 RTD Probe, batteries, manual, NIST-traceable certificate, test leads, and hard-sided carrying case.
