FYRA High Vacuum Gauge | Pirani & Capacitive Piezo

7.5×10-6 to 1000 Torr | TriSENS Gauge

The FYRA High Vacuum Gauge is paired with the TriSENS DPCP Quantum Sensor, which is a combined pirani, piezo, and capacitance manometer. It measures from 1000 Torr down to 7.5 x 10-6 Torr. The combined usage of the ultra wide range TriSENS DPCP and FYRA can eliminate the use of multiple sensors to interpret processes and data.

Vacuum Science Simplified

We know vacuum applications can get complicated. FYRA was created to deliver scientific measurement and vacuum control simply with easy integration into almost any system in the market. FYRA Features:

  • Easy integration into systems
  • Capable of driving multiple types of sensors (ex. piezo, thermal, active, passive, and capacitance manometers)
  • Has touchscreen and dial interface
  • Intuitively display and manage multiple sensors + control points
  • Comes standard with:
    • 10 Volt DC output for PLC integration
    • USB for data download + documentation of vacuum processing data-points

TriSens | DPCP Quantum Sensor

The DigiVac TriSens DPCP Quantum Gauge is an ultra wide range vacuum sensor that combines the novel Quantum pirani with piezo technology to deliver a measurement range of 7.5 x 10 -6 to 1000 Torr. 0-10V output, RS232 and 1 relay included.

This sensor establishes new standards with an all-in-one wide range measurement solution for a wide selection of vacuum applications. This transducer is an overall cost-effective solution with an ultra-wide 9 decade range that includes 5 decades of gas independent measurement. The Digivac TriSENS combines 3 technologies: Quantum Pirani, Capacitance, Piezo into an all-in-one gauge.
