Description:

As with the original high accuracy 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 psi 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-defi ned 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

/2

digit display with 0.65" high

graph. Accuracy is temperature-compensated over
a 0 to +50 °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, fi ltered
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 fi eld 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 incorporated
into a process line. A self-contained calibration kit
is available which includes a BetaGauge PIR, hand
pressure pump, and associated fi ttings.
