Martel's New BetaGauge 321 Dual Sensor Pressure Calibrator Provides Full Sale Accuracy

Martel Calibrators, a unit of Martel Electronics Corporation has announced its new BetaGauge 321 Dual Sensor Pressure Calibrator, which provides unmatched pressure measurement flexibility over any competitive unit.

The BetaGauge 321 Pressure Calibrator provides 0.025% Full Scale accuracy on both internal, isolated and 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 calibrator 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 (3) simultaneous measurements in any combination, including (3) three pressure measurements. With simultaneous display of two (2) pressure and an RTD temperature measurement, the BetaGauge 321 is ideal for gas flow calibration (custody transfer) applications.

The new BetaGauge 321 Dual Sensor Pressure Calibrator provides a number of convenience features. Temperature compensation ensures accuracy in field applications. A switch test can be performed on both internal or external pressure inputs. % Error and damping functions are provided. up to five frequently used setups can be stored and retrieved with one button recall; the last setup used is automatically recalled on power-up. The BetaGauge 321 provides layered operating modes, which both support simple measurements and complex applications. The large graphic-style LCD with backlight and three (3) "soft" function keys provide measurements that are easily read and setup. The compact, rugged design operates on standard AA batteries.

The BetaGauge 321 is available in two (2) standard configurations - 15 psi/1500 psi or 30 psi/3000 psi ranges - or customized with any two (2) ranges selected from 5, 15, 100, 300, 500, 1000, 3000, 5000, or 10,000 psi. It is also available in a Kit, which includes the BetaGauge 321 Calibrator, RTD PT100 Probe, batteries, manual, NIST-traceable certificate, test leads and hard-sided carrying case.
