IONIVAC ITR 90 - DN 40 CF-R - Profibus

ITR 90

The ITR 90 is a optimized combination transmitter. The combination of a hot cathode ionisation sensor according to Bayard-Alpert and a Pirani sensor permits vacuum pressure measurements of nonignitable gases and gas mixtures in the pressure range from 5 x 10-10 to 1000 mbar.

The ITR 90 can be ordered with an integrated display or Profibus interface.

Features and Benefits

• Continuous pressure measurements from 10-10 mbar to atmospheric pressure.
• High degree of reproducibility within the typical range for process pressures of 10-2 to 10-8 mbar.
• Controlled switching on and off sequencing through the integrated double Pirani optimized the service life of the yttrium coated iridium cathodes.
• Compact design.
• Enclosed, rugged electrode geometry in a rugged metal housing
• Efficient degassing by electron bombardment
• Simple fitting of the sensor
• Extension for higher bake out temperatures during the measurements
• One signal covering 13 decades - One flange joint for 13 decade
• TR 90 model with built-in display for stand-alone operation without additional display components.
• RS 232 C interface
