The Martel BetaGauge PIR Pro is a reference-class pressure gauge that takes the concept of a simple analog test gauge and combines it with the accuracy and features of digital technology. The PIR Pro provides exceptional performance with ±0.04% of reading accuracy, especially when operated below 50% of its range.

The BetaGauge PIR PRO is available in pressure ranges up to 10,000 psig. Additionally, a compound ranges is also available. Readings may be displayed in any one of 18 standard engineering units or in 1 custom user-defined unit to eliminate tedious conversion calculations. Rugged zinc-aluminum alloy high pressure cast housing provides environmental integrity of the gauge in a small, light package.

The PIR Pro includes a 5-1/2 digit digital display. The 0.65" numerals and companion bar graph provide an easy to read display, even from a distance. A number of features provide additional ease of use. The reading sample rate can be user adjusted to match the type of measurement required. Other features include MIN/MAX function, Auto Power Off and backlight control. In addition to a ZERO function that compensates for sensor drift, large residual system pressures can be nulled using the TARE adjustment.

Setting up the Martel BetaGauge PIR Pro is fast and straightforward, through a menu-driven display, with minimal text and intuitive functions. A password-protected field calibration may be initiated through the keypad and an RS232 port allows pressure reading data to be extracted directly from the gauge for off-line analysis (requires Martel RS232 cable). Damping can be set to integrate readings to accommodate pulsating sources, such as plant air. An optional external 24 VDC power input is available for applications where the BetaGauge PIR Pro will be permanently incorporated into a process line. A protective rubber boot is standard to help protect the BetaGauge PI Pro from damage when dropped.

The BetaGauge PIR Pro is available in a self-contained calibration kit which includes a test pump (with MECP500 pneumatic test pump for ranges 500 psi and below or a MECP10K hydraulic test pump for ranges above 500 psi), test hose, fittings, rubber boot and carrying case.
