IONIVAC ITR
The IONIVAC ITR 90 and ITR 200 are broad-range vacuum gauges that combine a Bayard-Alpert hot cathode ionisation sensor with a Pirani sensor in a single compact transmitter. They provide continuous pressure measurement from 5 × 10⁻¹⁰ mbar up to atmospheric pressure (1000 mbar), making them ideal for analytical instruments, coating systems, vacuum furnaces, research applications, and general high-vacuum processes. The ITR 90 features a single hot-cathode filament, while the ITR 200 incorporates dual filaments for extended service life and increased operational reliability through automatic filament changeover.
They must not be used for measuring flammable or combustible gases in mixtures containing oxidants (e.g. atmospheric oxygen) within the explosion range.
ITR 200
The ITR 200 S is an optimized dual filament combination transmitter on the basis of the well-proven ITR 90. The combination of a hot cathode ionization sensor according to Bayard-Alpert and a Pirani sensor allows vacuum pressure measurements of non-ignitable gases and gas mixtures in the pressure range from 5 x 10-10 to 1000 mbar.
Upon request, the pressure can be displayed on an integrated display.
ITR 200 S (without display, 1 switching function) / ITR 200 S (with display, 1 switching function) / ITR 200 SP (with Profibus interface, 2 switching functions) / ITR 200 SD (with DeviceNet interface, 2 switching functions)
