All you need to know about digital pressure gauges vs analog pressure gauges - pros, cons and suggestions for choosing the right gauge.
Regulatory demands have made the maintenance and calibration of process control instrumentation harder and harder. As the requirements of traceability have increased it has put more burden on those who manage these systems to keep track of more information on both the reference device, device under test, serial numbers and other data. This greater scrutiny has fallen on the instrumentation used on pipelines, refineries, pharmaceutical plants and other process control industries to measure the flow of liquids and gasses. Because of this added traceability requirement, it has grown more difficult to manage instruments in these industries.
Connect to all major connection standards - no matter who makes it. Our expanded line of DP Transmitter Adapters and Bleeder Screw Adapters are now available for Rosemount, Yokogawa, Endress+Hauser, Honeywell, Anderson Greenwood, NOSHOK and Parker.
The FieldLab Outdoor Enclosure along with a Ralston FieldLab Pressure Reference replaces paper-based pressure chart recorders with a digital solution. Instead of changing charts every week or month these can log for three months at a time or longer before data needs to be collected.
Ralston Instruments is excited to release a new 650 psi / 45 bar Pressure Test Pump that it is exceptionally durable and ready for heavy field use.
Ralston Quick-connect adapters can be assembled by hand - without a wrench or thread sealant and they seal up to 5000 psi / 350 bar.
The adapters use a pressure assisted sealing means the more pressure that is applied the better the seal. Connect to pressure gauges which have male NPT, BSPP or Metric threads all without using a wrench or thread sealant. Switch between gauges while calibrating or testing quickly and leak free.
Adapt a standard Pete's Plug (tm) to a Ralston Quick-test hose with our new Pete's Plug Adapters.
The probe in our adapter connects into any standard Pete's Plug (tm) and
allows the user to connect a Quick-Test Hose or Quick-Test Adapter on
the other side.
You're busy and don't have time to figure out all the items you need to
calibrate pressure devices. What if we could take the guesswork out for
you? Whether you're calibrating pressure transmitters, setting pressure
switches, checking gauges or verifying Flow Computers, we have the right
kit for you!
Create and run your own Calibration Test Modes for repeatable, traceable As Found/As Left tests for calibrating pressure gauges or other DUTs. Eliminate log sheets and hand written test points. Ditch the paperwork and get fast and accurate results with 100% digital traceability.
Use a FieldLab to do datalogging of pressure in a wide variety of situations. It can be used for logging pressure during hydrostatic testing, logging of pressure events, checking tire pressures or leak testing products. See how the FieldLab can help you do your job better.
FieldLab is the first pressure reference that is designed to work how you do whether it is on an oil rig, pipeline, power plant, aircraft carrier or ship. The FieldLab is rated Class 1, Division 1 Intrinsically Safe as well as ATEX and IECEx Zone 0 certified for use in hazardous locations.
The Ralston Nitropak is our high-pressure portable calibration kit with an on-board nitrogen cylinder. It allows the user to control pressure very precisely to devices in the field (up to 3000 PSI/ 210 bar) so that test points can be reached quickly.
The Ralston Instruments Volume Controller is an excellent solution for a wide range of Pressure Control Applications.
Ralston Instruments Universal Hose and Adapter Kits help take the guesswork out of selecting adapters. When you go out in the field you can be sure you have every hose and adapter you need to do the job.
Sand, dirt, natural gas liquids (NGLs), water and other liquids can be a serious problem when calibrating pressure instruments on oil or natural gas pipelines. When liquid is mixed in with gas it can contaminate pressure instrumentation and introduce measurement errors. This is particularly a problem when measuring low pressures or differential pressures as any liquid can increase measurement uncertainty. To help reduce measurement uncertainty and to prevent solids and liquids from contaminating your pressure instruments Ralston Instruments has introduced two helpful products.
Taking gas samples from low producing wells or low flow pipelines is a challenge. Ralston Instruments has created a solution to this problem.
Our new Pressure Regulation Kits come with everything you need right out of the box to connect to a compressed gas cylinder, control gas pressure quickly and precisely and connect your hose quickly to the device being calibrated.
As a result of several years of effort Ralston Instruments has been awarded ISO 9001:2008 certification. This certification is one of the most widely recognized international quality system standards. This has several real benefits to our customers.
Get to know the last hydraulic hand pump you will ever need to buy. See how to efficiently and quickly set up and perform calibration tests on a range of devices with on-board gauges or off-board pressure calibrators.
Do you have pressure calibrators, hand pumps or comparators with Medium Pressure fittings but cannot find the right adapter for your application? Do you connect to Medium Pressure fittings in the field or in the lab? Do you have trouble getting the correct Medium Pressure adapter due to limited pressure range, expense or lack of selection? If the answer is yes to any of these questions then we have the solution for you.
