Pressure Calibrator comes with 30 or 150 psia internal sensor.
July 30, 2010 -
Providing ±0.025% full scale accuracy, BetaGauge 330 uses absolute pressure internal sensors for pressure measurements in applications such as steam turbine power plants, chemical production, and petroleum refining. Unit allows calibration down to 20% of barometric pressure when coupled with built-in battery powered electric pump. Operating from 24 Vdc supply, calibrator includes built-in loop calibration, multi-variable display, and automatic pressure switch test.

New Ranges Featured for BetaGauge 330 Pressure Calibrator
In June, Martel Electronics began shipping the revolutionary BetaGauge 330 Electric Pump Pressure Calibrator with available absolute pressure internal sensors. The 330 is now available with a 30 PSIA (2 barA) or a 150 PSIA (10 barA) internal sensor. Absolute pressure is a barometric measurement referenced to a true full vacuum. These types of pressure measurements are common in steam turbine power plants, chemical production and petroleum refining.
Coupled with the 330's built-in battery powered electric pump, this allows calibration down to about 20% of barometric pressure. Greater vacuum can be achieved with the use of the calibrator's vernier adjustment or connection to an external high vacuum source.
The new ranges offer the same ±0.025% of full scale accuracy (6 month specification) as the previously offered gauge ranges (30, 150 & 300 PSI).
Some of the other features included with the BetaGauge 330 are built-in loop calibrator (input and output), large multi-variable display, 24 VDC instrument power supply, automatic pressure switch test, available gas custody meter calibration kit, 17 engineering unit display choices and external pressure module compatibility.
