Point Load Testing with a PG10 Digital Pressure Gauge

Digital pressure gauge for point load testingIn the civil, mining and geotechnical engineering realms, point load testing of core rock samples and irregular rock fragments are used to determine rock strength and rock compressive strength. This data is vital in when building tunnels, bridges and other buildings, where rock or ground integrity is always crucial to the support of structures.

The PG10 with its highly visible 2/3” LCD digits and 4.5 diameter face, is being used to monitor the force pressure in this type of testing. The PG10 is calibrated to read 99.71KN (kilo-newtons) at 10000 PSI.

Santa's PG7 Altimeter

Santa's Sleigh and ReindeerDuring the holiday season each year, we often hear familiar questions:

  1. Is Santa real?
  2. How do reindeer fly?
  3. How can Santa deliver presents to the whole world in one night?

  4. Or my favorite:
  5. What keeps Santa and his reindeer from passing out when flying at high altitudes?

While the first three questions are better left to other experts, APG provided a solution for question #4:

Which Pressure Gauges Should Be Digital?

digital process pressure gaugePressure gauges are perhaps one of the most important instruments in a plant’s tool belt. They are critical for both safety and process reliability. However, their importance seems to be underestimated, or even ignored.

A major analog pressure gauge manufacturer has found that in any given plant, *25% of gauges are broken and another 40% need immediate corrective action.

This alarming statistic is reflective of two problems. First, we don’t take pressure gauges as seriously as we should. Second, analog pressure gauges break too easily.

So with that in mind, we wanted to discuss which of those broken analog pressure gauges should be replaced with a more accurate, more durable digital pressure gauge.

3 Ways To Field Calibrate Your Digital Pressure Gauge

digital pressure gauge for pump monitoringThere is an important difference between a factory and a field calibration. A factory calibration will completely re-linearize your digital pressure gauge at multiple points. We perform calibrations on NIST certified equipment, and can therefore produce a NIST certificate if you so desire. We recommend you get a factory calibration once a year.

A field calibration is a quick way to get your gauge back in spec, and works great for fixing minor drift, installation shift, barometric pressure changes (for sealed units), or other minor discrepancies.

There are 3 ways to perform a field calibration on our digital pressure gauges:

On Digital Pressure Gauges, What Is The Difference Between Peak Hold & Tare?

they may sound similar, but peak hold and tare are very distinctDigital pressure gauges offer highly accurate readings, rugged durability, and several advanced features which dial gauges cannot compete with. Today, we will look at two of the more popular features that allow your digital gauge to tell you more than just the current pressure: Peak Hold and Tare.

The 7 Deadly Sins of Pump Control

Pump failure is expensive and can be preventedPump control was once an exciting job that, done well, kept pumps running maintenance free for many years at a time. Now, you may be lucky to have a pump stay out of the repair shop for two years – some only for six months.

What happened to pump control? Why are so many needing repairs so frequently?

The truth is, the right way to do pump control has been forgotten by many. It happened as older engineers, technicians, and operators retired. It happened as fluid dynamics classes in college spent less time on pumps....

3 Steps To Use Pressure Gauges The Right Way

Understanding how to use a pressure gauge is half the battleI once heard a major analog pressure gauge manufacturer state that pressure gauge failure is a great early warning sign for bigger problems.

That doesn’t make sense. Mostly because pressure gauges are meant to measure pressure, not to act as a canary in a coal mine – only noticed when it’s dead.

Oh, and it’s not an early warning sign either.

This just shows you how terribly misunderstood pressure gauges are...

Why A (Digital) Absolute Pressure Gauge Is Best For Pump Monitoring

How To Increase Your Pump's Reliability With Pressure Gauges

Proper pump monitoring starts with the right pressure gaugesThe only way to reliably monitor a pump is to install two digital pressure gauges – one on the suction nozzle, and the other on the discharge nozzle. Together with your pump performance curve, the gauges will tell you how well your pump is performing, and offer clues as to how you can improve its performance. A pump running at its Best Efficiency Point (BEP) will run with very little maintenance for decades.

Pressure gauge selection is an important step to making pump monitoring easy for your operators...
