The Martel BetaGauge 311A and 321A are designed to be simple to use yet very versatile pressure calibrators. The internal pressure sensors of the BetaGauge 311A and 321A can be combined with inputs for mA, voltage, switch contacts and an RTD probe to allow the 311/321 to calibrate virtually any pressure device. An external pressure module option allows an even wider range of pressure calibration options including absolute and differential.

The Martel BetaGauge 311A and 321A feature isolated, stainless steel, pressure sensors with 27 available pressure ranges. Accuracy across all ranges is 0.025% F.S. Temperature-compensation ensures accuracy in field applications. The BetaGauge 311A is a single sensor pressure calibrator while the BetaGauge 321A is a dual sensor pressure calibrator ideal for gas custody transfer. The 311A uses the P1 port for all pressure inputs. The P2 port is only used on the model 321A. Therefore on the model 311A, all menu choices involving pressure are limited to the P1 port only. All other model 311A features and functions are the same as for the 321A. Both the 311A and 321A are available in intrinsically safe models.

The Martel BetaGauge 311A and 321A both have a large graphic style LCD with backlight that can be configured to display up to 3 inputs simultaneously (i.e. pressure 1, pressure 2, and RTD or any combination of inputs). Pressure readings can be displayed in the user's choice of 19 engineering units. Setting up the 311A or 321A is simple and up to five frequently used setups can be stored with the last setup automatically recalled on power-up. Operating mode layers support simple measurements to complex applications.
