Before the BetaGauge 330, users had to manually generate pressures with tedious and hard to use manual pumps or use large, heavy and unwieldy boxes with limited portability and limited battery life.
The BetaGauge 330 has a form factor only slightly larger than Martel’s popular BetaGauge 321 and weighs in at a mere 2.5 pounds. The housing is contoured to easily fit a technician’s hand with good balance top to bottom. Performance doesn’t stop with the pump. The BetaGauge 330 provides ±0.025% of full scale accuracy on its internal, isolated pressure sensor. Temperature compensation on its internal sensor ensures accuracy in field applications.
A Pt100 RTD input is provided for temperature measurements accurate to ±0.1 °C (0.2 °F). In addition, the BetaGauge 330 measures and simulates 4-20 mA loop current signals. It can measure up to 30 VDC. An internal 24 VDC Instrument Power Supply supplies power to a transmitter under test.
Like its calibrator siblings, the 330 displays up to 3 calibration values at one time from the choice of internal pressure sensor, external pressure sensor, temperature from the optional RTD probe or electrical (mA or VDC). The display is a large back lit graphics style LCD that’s easy to read in any lighting condition.
The new BetaGauge 330 Pressure Calibrator provides a number of convenience features. Switch test can be performed on internal or external pressure input. Percent (%) Error and damping functions are provided. Up to five frequently used setups can be stored and retrieved with one button recall.
The compact, rugged design operates on eight (8) standard AA Alkaline batteries. Due to the power saving designs incorporated in the BetaGauge 330, it can perform approximately 300 calibration cycles to 150 PSI on one set of batteries.
The 330 comes in 3 ranges of 30 PSI, 150 PSI and 300 PSI. The 300 PSI version uses a manually operated handpump.
