Spend More Time Calibrating and Less Time Looking for Leaks

Ralston Quick-connect Adapters Do you find that when testing pressure instruments, connecting everything actually takes the longest time? Do you find that looking for leaks takes longer than doing the actual test!? Will not anymore! If you are connecting to pressure gauges using NPT or BSPP adapter then Ralston Quick-connect Adapters will make your job much easier.  If you are connecting to JIC/AN 37-degree flare connections in aerospace, marine or military applications then these adapters will allow you to spend more time calibrating and less time looking for leaks (saving you time and…Read more

Calibration of Temperature Sensors in the Process Industry

Temperature sensors within the process and pharmaceutical industries are important devices in ensuring that the process runs smoothly and product specifications are met on a continuous basis.  The calibration of these sensors on a regular schedule is important to provide confidence in the measurements being taken and thus the quality of the end product being produced.  This blog looks at the various types of temperature sensors, contrasts the value/benefit of dry-block calibrators verses liquid bath calibrators, and the effective process to follow in specifying and procuring temperature calibrators. Where are the temperature sensors…Read more

Using the Ralston Instruments Volume Controller for Pressure Control Applications

The Volume Controller (QTVC) from Ralston Instruments is the ideal lab tool.  Calibrate both very low pressure or high pressure instrumentation using nitrogen with an attached pressure gauges or calibrator.  The proprietary pressure balanced fine adjust piston allows for extremely precise, finger-tip control of pressure at 0.03 psi (2 mbar) or 3000psi (210 bar) or any range in between.  The test system includes a handle, Quick-test System outlet connections, hoses and adapters.  The Volume Controller is a versatile instrument useful for many types of calibration processes.  Find out more below and watch the…Read more

Is Your Pressure Pump Really Leaking?

Archimedes-born in 287 BC - was a practical man and took full advantage of Laws and the repeatable behavior of Physics.  He invented a variety of machinery including a screw pumping device that lifted water from a river to irrigate field crops.  Today we employ the same laws and engineering to manufacture a variety of pumps for many different applications.  All of these pumps make life easier and surely Archimedes would approve.  Regardless of the type, under some circumstances they still leak or appear to leak, what can we do about it? The…Read more

What you need to know about Pressure Gauge Calibration

To start off our discussion of calibration and its importance we should first start with a clear definition.  Calibration is a comparison between measurements - one of known magnitude or correctness made or set with one device and another measurement made in as similar a way as possible and with a second device.  The device with the known or assigned accuracy is called the standard.  The second device is the unit under test.  There are a couple of different methods of collecting calibration data; Cardinal Point Calibration and, Nominal Point Calibration.  For the…Read more
