The BetaGauge 330 is a revolution in pressure calibration technology for the process industries. With the 330, technicians have a small, lightweight calibrator that generates from high vacuum to 300 PSI using a high performance integral electric pump. Gone is the drudgery of manual pumping or using large, heavy and unwieldy boxes with limited portability and poor 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 ±0.035% of full scale accuracy on its internal, pressure sensor. Temperature compensation on its internal sensor ensures accuracy in field applications. An external pressure module connection supports all 29 ranges of BetaPort-P pressure modules for even greater measurement capability 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.
