TTR91 / Display 1

TTR91 transmitters are active sensors using thermal conductivity according to Pirani. The TTR91 uses an easily replaceable and robust Pirani sensing cell that can be easily aligned to any precisely known pressure value by pressing a button. The transmitter has a very fast response and is highly resistant to overpressures, plus optimised temperature compensation results in stable measurements. It is well suited to applications of safety circuits in vacuum systems, controlling ionization gauges and analytical engineering. It is also suitable for pressure measurement and control on systems in the fine and rough vacuum range requiring digital display, low voltage power supply, (0-10V) chart recorder output, user selectable (mbar, torr or pascal) read out and high reliability together with simple operation.
