Precise Compressed Gas Pressure Control for Smart Calibration

Precise control of compressed gas is an intelligent approach to calibration. Ralston Instruments offers smart ways of compressed gas pressure control, better than anyone in the industry. Our exclusive range of precision calibration equipment is able to control compressed gas at any pressure level – vacuum, low pressure (0 to 7 bar), medium pressure (7 to 20 bar), and high pressure (20 to 350 bar).


Applications

Ralston precision pressure controllers can be used for a wide range of industry applications such as:

  • Absolute pressure measurement
  • Vacuum gauge calibration
  • Airspeed indicator calibration under low pressure
  • Pressure gauge calibration
  • Calibrating pressure transmitter
  • Deadweight replacement
  • Calibrating a static pressure transmitter under medium pressure
  • Testing safety relief valves
  • Calibrating pressure gauge under high pressure


Ralston Compressed Gas Volume Controller for Optimum Pressure Calibration

Perform both ultra-precise low-pressure differential or high-pressure static pressure calibrations with nitrogen using the same device with an external pressure calibrator.

A conventional pressure regulator functions by filling & bleeding the pressure. Ralston compressed gas volume controller helps you seamlessly perform accurate high pressure static calibrations or low-pressure differential calibration. It ensures stability and precision at any pressure level.

Calibration in Remote Locations Made Easy with Ralston NitroPak

Self contained nitrogen source, regulator, precision fine adjust, hoses, gauge adapters and process connections provide a complete pressure control solution for doing nitrogen calibration of pressure instruments in remote locations.

The fully integrated compressed gas source kit has everything you need to perform calibration in remote locations. Ralston NitroPak includes a compressed gas cylinder, hoses, pressure regulator, and adapters. It ensures quick set up and accurate compressed gas pressure control, despite difficulties working in a remote location.

Excellent Control Over Compressed Gas with Calibration Manifolds

An excellent solution for doing static pressure calibrations with compressed nitrogen gas. Brass and stainless steel manifolds are available to provide solutions for every type of environment. The most economical way of performing static pressure calibrations in the field using nitrogen or other compressed gas.

Ralston pressure calibration manifolds are made using highest grade materials to perform unmatched static pressure calibrations in the field or in the shop. It provides fine control over a compressed device, irrespective of the device being controlled.

We also provide pressure regulators, Benchtop manifolds, and fluid & gas filters for high-precision & stable Benchtop calibration.
