ACTIVELINE GAUGESThe new ActiveLine PKR and IKR gauges.
Compact, durable and maintenance-friendly, minimized stray magnetic field.

Longer service life,easy maintenance

Various new developments have substantially improved thedurability of these gauges: The new dual-chamber design
ensures that contaminants are collected in the first chamberwhile the second chamber offers a clean area for vacuum
measurements. The texture of the surface inside the measurement chamber prevents measuring errors or faults causedby self-sputtering effects. The measurement chamber andthe ignition tool are easy to replace, facilitating effortless
maintenance.

Pure cold cathode andFullRange® gauges

The new gauges are available as pure cold cathode gauges
IKR 360/361 and as Pirani cold cathode gauges PKR 360/361.
The IKR gauges cover the pressure range from 1 · 10-2 to
1 · 10-9 hPa, whereas the FullRange® PKR gauges allow
atmospheric pressure measurements up to 1 · 10-9 hPa.

Compact dimensions

The new gauges are significantly smaller than conventional
vacuum gauges (IKR/PKR2XX). This facilitates installation in
new and also in existing applications.

Variant with increased
corrosion protection

With an optional ceramic coating, these gauges can also
be used in corrosive applications. The coating protects thevacuum feedthrough as well as the Pirani filament.

High and low current
versionFor optimal process compatibility they are available as alow current version (IKR 360 and PKR 360) and as a highcurrent version (IKR 361 and PKR 361). The low current
version is especially suitable for applications in the medium
vacuum range, in order to prevent contamination in thispressure range. The high current version, on the other hand,is the version of choice in high vacuum, in order to achieve
optimal ignition characteristics even at low pressures.

The innovative design minimizes the stray magnetic field. This
is of particular benefit in applications where external magnetic
fields are undesirable (e.g. mass spectrometer or electron
microscope). With the new IKR 360/361 and PKR 360/361,
elaborate and expensive magnetic shielding becomesobsolete.
