FYRA High Vacuum Gauge | Pirani & Capacitive Piezo

7.5×10-6 to 1000 Torr | TriSENS Gauge

FYRA Vacuum Gauge Controller – DigiVac’s Latest Innovation

FYRA high vacuum gauge measures from 1000 Torr down to 7.5 x 10-6 Torr includes the TriSens transducer (sensor) a combined pirani, piezo & capacitance manometer. The DigiVac FYRA vacuum gauge controller is a digital vacuum control instrument that employs a 3.9” capacitive touch screen and includes a tactile knob to easily interact with the vacuum gauge functions.

Need vacuum control too? The FYRA gauge controller is modular and can be upgraded to include vacuum control.

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.

Sensor Details

The DPCP Quantum | TriSENS Vacuum 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: Quantum Pirani, Capacitance, Piezo all-in-one gauge

With the combined usage of the ultra wide range TriSENS DPCP and FYRA you no longer will have to use multiple sensors to interpret the process and data.

  • The all-in-one ultra wide range vacuum sensor combines 3 vacuum technologies: the novel MEMS pirani, Capacitive (Capacitance Manometer) and Piezo technology to deliver a measurement range of 7.5 x 10 -6 to 1000 Torr.
  • The Digivac TriSENS Vacuum Sensor Delivers High Vacuum Measurement + Process Control + Overpressure Indication All in One
  • Accuracy Specifications: 1000 Torr to 5 Torr =  +/- 3% 4.99 Torr to 10-5 Torr = +/- 14% 10-5 to 10-6 Torr = +/- 50%
  • Deep & Wide Vacuum Measurement : Highly accurate direct pressure measurement down to 10 microns (.01 Torr) combined with high vacuum measurement down to 10-6

  • High Vacuum Gauge Measurement range:  7.5×10-6 to 1000 Torr
  • Patent-pending Quantum Pirani that extends the measurable vacuum range by up to 3 decades combined with trusted rough vacuum piezo technology delivers a range of 9 decades. All at an attractive price point.
  • Contamination Containment: Integrated baffle helps protect sensor elements from particulate contamination and increase its longevity

  • Visual Process Indicator: Multi-color LEDs to indicate pressure range. Includes a bright yellow overpressure indicator to help you avoid system damage. This is very useful when not using a display controller

  • Ideal for Clean Processes: 1000 Torr down to 10-6 Torr with no ion gauge required. Includes integrated baffle to protect and extend life of sensor
