Leybold Releases THERMOVAC TTR-RN Filament Pirani Gauges

The ability to reliably measure and control the vacuum level in each vacuum process is key in creating the highest efficiencies. Therefore, Leybold has developed the THERMOVAC TTR-RN series, a new compact filament Pirani gauge for all vacuum applications requiring a measurement range from atmosphere to 1e-4 mbar (7.5e-5torr). With compact dimensions and rugged filaments, this latest innovation from the vacuum specialist is equally well suited for analytical applications and robust industrial processes. All in all, the use of the THERMOVAC TTR-RN series from Leybold will support users to monitor small and large vacuum systems more easily and thus be able to control and scale them in a more targeted manner. The THERMOVAC TTR-RN series is globally available from today onwards.

Leybold THERMOVAC TTR-RN series compact filament Pirani gauge for all vacuum applications.

The core element of the measuring device is its new filament technology. By advancing filament technology Leybold increases the sensitivity and thus the accuracy of measurements. This has been coupled to high end electronics and interfaces, including a bright light ring which immediately indicates the pressure range locally. With reliable and reproducible measurement results, even the roughest vacuum processes can be optimized easily and quickly. As a result, dead process time is reduced and the throughputs in the vacuum processes are increased.

For standard processes, the THERMOVAC TTR-RN series has a tungsten filament, while for harsher process applications a corrosion resistant platinum variant is available. To further increase the reliability of the gauge a filter is integrated into the flange, blocking particles that would otherwise damage the filament. The THERMOVAC TTR-RN Pirani gauges series is available with many flexible options to suit your need – starting with standard or corrosion-resistant measuring cells which can be combined with an array of flange types, communication protocols (0-10v, RS232, RS485) and output scaling options.

Regular maintenance can be easily carried out by end users themselves and without the need for any special tools. Separating the two halves of the meter only takes a simple pull of the pin on the side. Both the cell and individual electronic components are available as spare parts. Based on its many years of experience in the field of vacuum measurement, Leybold can also ensure the individual application and after-sales support required in each case.
