The Penningvac PTR series belongs to the broad - range vacuum gauges. It is designed to be robust, reliable, and accurate, enabling pressure measurement in the high - vacuum region, and can be regarded as a full - range gauge.
Types and Principles - PTR 90 RN: It is a combined cold - cathode gauge that uses the inverted magnetron principle of cold - cathode ionization and combines it with a Pirani gauge. By integrating the two technologies into a single, more compact sensor, the measurement range is expanded, enabling reliable pressure measurement from atmosphere to 1\times10^{-9} mbar. The on - off function of the cold cathode is automatically controlled by the integrated Pirani gauge, which can avoid the risk of running the cold cathode at too high a pressure and prolong its service life. - PTR 225 RN: It is a pure cold - cathode gauge that uses the Penning principle of cold - cathode ionization. Its measurement range is from 10^{-2} to 10^{-9} mbar, which allows measurement in the high - vacuum region. To control the startup of the gauge, it is best to combine it with one of
Thermovac or Ceravac gauges.
Features and Advantages - Compact size: It is easy to integrate into various systems. - Rugged cold - cathode design: It is durable and requires little maintenance. - Customizable: It has a wide range of interface options, which makes it easy to integrate into specific systems. Both analog 0 - 10V linear outputs and digital communications are available.
