As with the original high accuracy Martel BetaGauge PI gauges, the BetaGauge PIR takes the concept of a simple analog Test Gauge and combines it with the accuracy of digital technology. The new Reference Class gauges provide exceptional performance with +/-0.04% of reading accuracy, especially when operated below 50% of their range.. The Reference Class BetaGauge PIR digital test gauges are available six ranges - 30 PSIG Compound, 30 PSIG, 100 PSIG, 500 PSIG, 1,000 PSIG, and 3,000 PSIG. Setup of the BetaGauge PIR is fast and straightforward, through a menu-driven display, with minimal text and intuitive functions, that is simple enough to allow the gauge to be used anywhere in the world without the need for multilingual displays.
Pressure readings are displayed in any one of 18 standard engineering units, or in user-defined custom units, eliminating tedious conversion calculations. Readings are displayed on a 5-1/2 digit, 0.65” high digital display and companion percent-of-range bar-graph. Accuracy is temperature-compensated over a 0 to +50 Deg C range. The internal temperature sensor measurement can be displayed in degrees Celsius or Fahrenheit.
The BetaGauge PIR provides an unmatched feature set, offering the user many options for ease-of-use. The reading sample rate can be adjusted to match the type of measurement, such as for pressure switch threshold points, instrument-grade readings, filtered readings, and a power-saving 1 reading per 2 seconds “sleep” mode. A MIN/MAX function instantly recalls pressure reading extremes. In addition to a Zero function, large residual system pressures can be nulled using the TARE adjustment.
When combined with custom engineering units, the TARE adjustment allows the BetaGauge PIR to be used in a variety of liquid level and volume measurements, easily reading units of interest directly, such as gallons in a tank. Password-protected field calibration may be initiated through the keypad. An auto shutoff feature may be enabled for a preset interval to extend battery life. Damping can be set to integrate readings to accommodate pulsating sources, such as plant air.
An RS232 port allows pressure reading data to be extracted directly from the gauge for off-line analysis. A protective rubber boot is provided as standard to help protect the gauge from damage if dropped. A number of options are available for the BetaGuage PIR Digital Pressure Gauge making the gauge suitable in virtually any application. An optional 24 VDC external power input is available for applications where the gauge will be permanently installed or used continuously. A self-contained calibration kit is available which includes a BetaGauge PIR, hand pressure pump, and associated fittings.
