October 17, 2008 - Tom Fatur, President of Martel says, "The new BetaGauge 330 Pressure Calibrator has been engineered to put an end to the complicated use of hand operated pumps for pressure calibration. With the new BetaGauge 330, technicians will have a lightweight hand held calibrator that generates pressures up to 150 PSIG (10 Bar/100 kPa) using a high performance integrated electric pump. 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. That time has come to an end."
The Hand Held Pressure Calibrator has a form factor only slightly larger than Martel's popular BetaGauge 321 Dual Sensor Pressure Calibrator and weighs only 2.5 pounds (1.1 kg). The housing is contoured to easily fit a technician's hand.
A Pt100 RTD input is provided for temperature measurements accurate to ±0.1°C (0.2°F). This facilitates the calibration of mass flow computers.
In addition, the BetaGauge 330 calibrator measures and simulates 4-20 mA loop current signals. It can measure up to 30 Volts DC. The pressure calibrator sends power to a transmitter under test using an internal 24 Volt DC power supply.
Like its BetaGauge calibrator siblings, the hand held pressure calibrator displays up to 3 calibration values from either the internal pressure sensor, external pressure sensor or temperature from the optional RTD probe. The display is a 128 x 64 pixel back lit LCD that's easy to read in any lighting condition.
The BetaGauge 330 calibrator provides ±0.025% of full scale accuracy on its internal, isolated pressure sensor. Wide range temperature compensation on its internal sensor ensures accuracy in field applications. An external pressure module connection supports 29 ranges of BetaPort-P pressure modules for greater measurement capability.
The new Hand Held Pressure Calibrator provides a number of convenient features. Switch tests can be performed using the internal or external sensor inputs. Percent (%) error and damping functions are also provided. In addition, Up to five frequently used setups can be stored and retrieved with one button recall. Pressure signals can be displayed in the user's choice of 19 engineering units to fit the specific requirements of the job.
The compact, rugged design operates on eight (8) standard AA Alkaline batteries. The power saving design incorporated into the pressure calibrator, allows it to perform 300 calibration cycles to 150 PSI on single set of batteries.
The pressure calibrator is available in 3 ranges: 30 PSI (2 Bar/20 kPa), 150 PSI (10 Bar/100 kPa) and 300 PSI (20 Bar/200 kPa). The 300 PSI version uses a manually operated hand pump. All ranges are capable of generating and reading vacuum as well as pressure.
Like all Martel calibrators, the BetaGauge 330 Hand Held Pressure Calibrator comes from the factory ready to go to work. Batteries are included along with NIST traceable calibration certificate, test leads, test hose, carrying case and user manual. The calibrator is also available in several kits with RTD probe, adapter fittings and hoses.
Martel Electronics Corporation offers a diversified line of hand-held and bench calibrators, process instruments, process indicators, power supplies, meters and displays, and test and measurement instruments manufactured to the highest quality standards for the process industry and OEM applications.
