Pfeiffer PKR 361 w/ NW-25 – High Current ActiveLine Gauge, 25 ISO-KF

• Nominal diameter: 25 ISO-KF
• FullRange gauge with two sensors in one housing
• Very low external magnetic field
• Display range: 1 · 10-9 – 1000 hPa
• The maximum pressure applies to inert gases and temperatures below 55 °C

Total pressure vacuum gauge with analog signal outlet

The ActiveLine series offers a wide range of vacuum gauges that work on a variety of measuring principles and have a classic analog outlet. The series thus covers the technically relevant vacuum range from ultra-high vacuum to overpressure. The outlet voltage of the transmitter, that is proportional to the pressure, can be displayed as pressure on the three controllers or read into controllers through analog inputs for further processing.

The 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 the durability of these gauges: The new dual-chamber design ensures that contaminants are collected in the first chamber while the second chamber offers a clean area for vacuum measurements. The texture of the surface inside the measurement chamber prevents measuring errors or faults caused by self-sputtering effects. The measurement chamber and the ignition tool are easy to replace, facilitating effortless maintenance.

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.

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

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 becomes obsolete.
