BetaGauge 330 has absolute pressure ranges

In June, we started shipping the BetaGauge 330 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. Coupled with the 330’s built-in electric pump, this allows calibration down to about 20% of barometric pressure. If needed an external high… Read more »

BetaGauge 330 Valve Cleaning Video

We have posted a new video on YouTube that details the cleaning process for the BetaGauge 330 pump valves. The 330 has been a really trouble free product except that many users don’t bother to try cleaning the pump valves if they become contaminated. They end up sending it in for service that they could… Read more »

Custody Transfer – It's the Law

Did you know that the accuracy and validity of natural gas custody transfer metering is covered under the US Sarbanes Oxley law? I didn’t either until I read this informative post by Jim Cahill over at the Emerson Process Experts blog. Here’s my short take on what’s required to do a professional job at custody… Read more »

Martel Updates BetaGauge Calibrators

We have updated the very popular and powerful BetaGauge 311 and BetaGauge 321 Advanced Pressure Calibrators. The new models are the single range BetaGauge 311A and dual range BetaGauge 321A. What we didn’t change are the great performance and ease of use we already had. Here are the new features: Super rugged “Power-Tool-Tough” housing. We’re… Read more »

BetaGauge 330 FAQ – 3

Q. Can the BetaGauge 330 be field recalibrated? A. Yes. The BetaGauge 330 is calibrated through the serial port like many Martel calibrators. Other than a computer with a terminal emulation program (we normally recommend HyperTerminal), a LEM232 serial communications cable is needed along with a URA-1 RTD adapter. Both of these can be purchased… Read more »

BetaGauge 330 FAQ – 2

Q. How often do I need to change the batteries? A. On the BetaGauge 330-150, we have tested the battery life by repeatedly cycling the pump to 150 PSI. Similar to the test for pump life, the cycle went to 150 PSI ten times and then rested for ten minutes.  This is a much higher… Read more »

BetaGauge 330 FAQ – 1

Q. How long does the internal electric pump last? A. Under normal use the BetaGauge 330 internal pump can be expected to last a minimum of 5,000 cycles to full pressure before requiring a rebuild. Since the pump won’t normally always be cycled to full pressure (typically 150 PSI / 10 Bar / 100 kPa),… Read more »

BetaGauge Makes Pressure Switches a Snap

One of the common and more tedious jobs done in the calibration field is pressure switch testing. The new BetaGauge 330 actually makes this job easy and relatively quick. We have put in some special features for this particular task. When the pressure switch function is selected, the calibrator goes into a special high speed… Read more »

History of the BetaGauge-Part IV

Martel is making history with the latest iteration of the BetaGauge, The model 330. This is the first handheld pressure calibrator with a built-in ELECTRIC pump to generate test pressure from high vacuum to 150 PSI (10 Bar/1000kPa). We’re calling it fingertip calibration. All the tech needs to do is push the button. An electric… Read more »

History of the BetaGauge – Part III

The BetaGauge PI was engineered as a completely new addition to the BetaGauge line in the form of a digital test gauge. Although it’s not strictly a calibrator, the use of the familiar BetaGauge name was judged to be a good marketing move. By the way, the PI in the name is short for Pressure… Read more »
