Setup of BetaGauge P. I. PRO is fast and straightforward, through a menu-driven display, that is simple enough to allow the gauge to be used anywhere in the world. The BetaGauge P. I. PRO first and foremost, provides 0.05% of full scale accuracy of pressure in any one of eighteen (18) ranges. Readings may be displayed in any one of 23 standard engineering units, or in 1 custom unit you define, to eliminate tedious conversion calculations.
The 5 digit, 0.65" high digital display and companion percent-of-range bar graph provide an easy to read display, even from a distance. The sample rate can be user adjusted to match the measurement required. A power saving mode maximizes battery life to 2,000 hours. Other features include MIN/MAX function, Auto Power Off and backlight control.
Password-protected field calibration of the BetaGauge P. I. PRO may be initiated through the keypad. An RS232 port allows pressure reading data to be extracted directly from the gauge for off-line analysis.
(Requires Martel RS232 cable (P/N C232SJ).) In addition to a ZERO function that compensates for sensor drift, large residual system pressures can be nulled using the TARE adjustment. This adjustment, when combined with the ability to create custom engineering units for display, allows the BetaGauge P.I. PRO to be used in a variety of liquid level and volume measurements, easily reading units of interest, such as gallons in a tank, directly.
