Martel Electronics Corporation
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.
