Roessel helium leak testing service

As part of Roessel's continuous services, Roessel Messtechnik offers a new service to support their customers.

The tightness of building components or equipment depends on their intended purpose and the allowable leakage rate. There is no absolute tightness. If the leakage remains below the limit fixed for the component, the component is considered technically tight.

To quantitatively assess leakage, the term "leak rate" is introduced (as the symbol "gL"). In vacuum technology, the unit for leak rate is defined as (mbar * L) / s. If, in a vacuum, the leak rate value is 1 mbar * L / s - for a reservoir with a volume of 1 liters, the pressure changes by approximately 1 millibar within 1 seconds, or the pressure drop in the reservoir is about 1 millibar. In practice, permissible leak rates (from an agreed 100 (mbar * L) / s to <10-11 (mbar * L) / s) require the use of different tightness testing methods and equipment.

In addition to establishing total leakage, leak localization is of interest, allowing leaks to be removed in a targeted and appropriate manner. Using the introduced leak detectors, you can not only find leaks specifically but also check the overall leak rate of the test object.

Weidou Intelligent Technology professionally acts as an agent for the sales of the full range of Roessel temperature sensors, Roessel thermocouples, and Roessel thermometers, providing high-quality services to customers through close cooperation with the manufacturer.
