Ralston Instruments has passed the rigorous testing scheme for CE certification in the European market.
Ralston Instruments Introduces New Quick-test Hose Configurator OCTOBER 2011
The new Ralston Instruments Quick-test Hose Configurator allows you to customize the exact hose you need for a very specific job. When our standard hoses do not meet your exact criteria, our custom hoses provide you with additional flexibility to help you get exactly what you need for your job.
Ralston Instruments tube adapters make connecting to tube fittings quick and leak-free, all without a wrench AUGUST 2011
Traditionally, tube fittings have been designed to be made up at 1.25 turns. However, when they are disassembled and reassembled they often get tightened beyond 1.25 turns. Over time, this pattern of excessive tightening results in the front ferrule digging into the tube and making it bulge out in a way that puts excessive wear and tear on the fitting. Not only does this cause leaks but it also makes the nut harder and harder to spin thus reducing the life of the fitting. Now there is a better way to connect to a tube fitting.
Ralston Instruments Introduces 90 Degree Elbows JUNE 2011
Ralston Instruments introduces new 90 Degree Elbows. Connect to transmitters in hard to reach places.
A better way to calibrate chart recorders on natural gas pipelines FEBRUARY 2011
Todd has to calibrate multiple chart recorders on a gas pipeline but he has a problem. Since it is a natural gas pipeline he is concerned about using hydraulic fluid to do the calibration. It is also the middle of winter and he doesn't want any fluid to accumulate and freeze in the chart recorders. He has also had problems with pressure stability when using hydraulic fluid. The solution is to use a Ralston Instruments calibration manifold.
Ralston Instruments expands line of Quick-test XT hose and adapters DECEMBER 2010
Over the last several months, Ralston Instruments has introduced a new line of Quick-test XT fittings and hoses. The added flexibility that comes with these products enables you to work more efficiently and ensures you have just the right tools to accomplish your job in a variety of different settings.
See how Dave used Ralston adapters to make connecting to pressure devices in the field OCTOBER 2010
Connecting to devices in the field is difficult and time consuming.
New application guide helps find the right product for the job AUGUST 2010
Based on our approach to pressure calibration we have made it easier to find products. We have organized our products into 4 concepts: Connect, Create, Control and Calibrate.
How the Quick-test system works JUNE 2010
Making Connections Using the Ralston Quick Test System is quick and easy. Connect to virtually any pressure system to 10,000 psi without thread sealant or a wrench.
Connect to pressure sources and references using the Quick-test system JUNE 2010
The Quick-test System lets you connect to any pressure calibrator, pressure gauge, hand pump or pressure source easily and quickly.
How Tube fittings, Flare fittings, Medium and High Pressure and SAE O-ring Seals Perform APRIL 2010
There are several connections that are used for higher pressure connections where taper seals are not ideal. These connections use either a metal to metal seat or an o-ring seal to make a pressure tight seal at high pressures.
The difference between NPT, BSPP and BSPT seals FEBRUARY 2010
Pressure systems in the process industry use different ways of sealing depending on the geographical region, size of the pressure system and the environment. There are regional differences in sealing types as well as industry preferences. For example, many pressure systems onboard ships use BSPP adapters while many applications in the oil and gas industry use NPT fittings. While one sealing style is not inherently better than another each style has its application.
New adapter search helps make finding the right adapter a snap OCTOBER 2009
Ralston Instruments has developed a new adapter search that makes finding the right adapter for the job even easier than ever. Whether you are trying to connect to an NPT connection with a cap and chain or a tube fitting the adapter search can help you find the correct adapter.
A Green Approach at Ralston Instruments JULY 2009
When Ralston Instruments initiated the construction of their new headquarters building in 2007, they considered the impact they would have on the environment throughout the project and beyond. As a company that values the natural world around them, Ralston Instruments vowed to reduce their energy consumption and offset damage to the environment at each step. This dedication and “green” philosophy is the driving force behind how Ralston Instruments operates today.
The Revolutionary Ralston Instruments Calibration Manifold MAY 2009
The Problem Calibrating pressure instruments by filling and bleeding valves can cause pressure to jump around while trying to achieve a specific set point. Moreover, “Christmas trees” made from multiple valves and fittings are cumbersome and can lead to leaks. Calibrations performed with these configurations yield inaccurate results due to hysteresis error and waste valuable nitrogen.
Differential Pressure Calibration using Nitrogen MARCH 2009
Performing differential pressure calibration is challenging for a variety of reasons. As a world-renowned manufacturer of pressure calibration equipment, Ralston Instruments anticipates these situations and has created products that stand up to each challenge.
Ralston Instruments releases Quick-test XT 10,000 psi hoses and adapters OCTOBER 2008
Ralston Instruments is proud to introduce our new 10,000 psi calibration hose and adapters.
Static pressure calibration using nitrogen and hydraulic fluid SEPTEMBER 2008
Using a pressure regulator and needle valves to control pressure during a static pressure calibration is very difficult. Using a Ralston calibration manifold, volume controller or Nitropak saves nitrogen, time and money.
Use nitrogen to generate accurate pressure when calibrating pressure instruments JULY 2008
Using nitrogen when calibrating pressure instruments provides clean, accurate pressure and easy control of the device under test. For pressures under 3000 psi it offers the ideal set of features for pressure calibration.
Collaboration with domestic suppliers creates a winning approach MAY 2008
Ralston Instruments has a long history of making products in the United States. For almost 40 years, we have designed, marketed, manufactured and serviced pressure calibration equipment in Northeastern Ohio on the shores of Lake Erie.
Ralston Instruments new headquarters MARCH 2008
Our new building will help us provide customers with improved delivery, higher quality products, faster service and more innovative products.
Ralston Instruments breaks ground on new manufacturing facility SEPTEMBER 2007
On June 1st, 2007 Ralston Instruments broke ground on their new manufacturing facility. Located in Newbury, OH about 30 miles outside of Cleveland, the new building is 10,000 square feet and includes a multi-product production line, a QA center and an R&D lab for new product development.
Ralston Instruments takes to the road SEPTEMBER 2007
The coming year will be a busy time for Ralston Instruments. Marketing Director, Griffin Ralston, will be exhibiting at a number of trade shows. While he is on the road, Griffin will be demonstrating their new Male Quick-disconnect fitting that reduces set up time by eliminating the need to use thread sealant on pressure transmitter connection. This design streamlines the calibration process and enables service technicians to work faster. Come see Griffin and the Male Quick-disconnect fitting.
Faster, more efficient pressure calibration with the Male Quick-disconnect NPT Adapter SEPTEMBER 2007
Customers are now able to order our newest product the Male Quick-disconnect NPT adapter. Similar to our current model of male NPT adapter but, unlike the standard male adapter, the Quick-disconnect does not require the use of thread sealant and therefore significantly streamlines the calibration process. We also offer a full complement of hoses and hand pumps that can be used to create and connect the pressure to the device being tested.
