The BetaGauge 321 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 321 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 321 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 (custody transfer) calibrations.

The BetaGauge 321 is available in two standard configurations; 15 psi/1500 psi or 30 psi/3000 psi ranges, or customized with any two ranges selected from 5, 15, 30, 100, 300, 500, 1000, 1500, 3000, 5000, or 10,000 psi.

Available in a Kit, which includes the BetaGauge 321 Pressure Calibrator, Pt100 RTD Probe, batteries, manual, NIST-traceable certificate, test leads, and hard-sided carrying case. Also available with single pressure sensor as the BetaGauge 311 and economy version single sensor as the BetaGauge 301

AI Overview BETA

The Martel Electronics BetaGauge 321 is a pressure calibrator that measures pressure, temperature, loop current and voltage for instrument and transmitter testing. It displays up to three simultaneous measurements in any combination, including pressure and temperature for gas flow custody-transfer calibration work. Temperature compensation maintains measurement accuracy when the BetaGauge 321 is used in field applications.

Two isolated stainless-steel pressure sensors, each with 0.025% FS accuracy
External connection supports all 25 BetaPort-P pressure module ranges
Measures 4–20 mA loop current and voltage up to 30 VDC
Internal 24 V loop supply powers a transmitter under test
Stores up to five frequently used setups and recalls the last at startup
