Description
FYRA is DigiVac’s modular vacuum measurement and control platform: a 3.9 in touchscreen controller with six card slots, bench-top or pole mounting, and support for a wide range of third-party and DigiVac sensors. This listing is the vacuum regulator configuration, described as covering 10 millitorr to 6 Torr with two sensors – one at the roughing pump and one on the system – so that pump inlet pressure and process pressure are visible at the same time.
How throttle regulation works
The throttle regulation card presents two valve ports, each with its own upper and lower set point (U1/L1 for valve 1, U2/L2 for valve 2). The FYRA powers a 24 VDC valve directly rather than through an external relay: it opens the valve until the lower set point is reached, then closes it and allows the system to leak up to the upper set point, at which point the valve opens again. The gap between the two set points is the control hysteresis – a narrower band gives tighter control at the cost of more valve cycling. The valve is installed between the pump and the vessel, with the sensor placed near the vessel being controlled.
FYRA can also vent rather than throttle, using bleed control either to deliver a specific flow rate into a chamber or to hold a vacuum level by bleeding gas in.
Specifications
Display: 3.9 in touch screen. Mounting: bench top or pole mount. Power: 100-240 VAC 50/60 Hz. Units: Torr, mbar, kPa, microns, millitorr, mmHg and hectopascal. Telemetry: USB and 0-10 V analogue in and out, with WiFi as an option. Valve support: Dinamo proportional valve, VacStable bleed, solenoid-type bellows and plunger valves, and 24 V valves drawing less than 24 W. Certifications: UL, CE and CSA.

DigiVac SEN-VGT500, SEN-775i and Quantum (SEN-DPP, SEN-DCP, SEN-DPCP); MKS Convectron 275071 (1/8 in NPT) and 275203 (KF16); Agilent FRG700, PCG-750, PCG700, 531, 536, 531 equivalent and PVG 500; Pfeiffer PKR251 and IKR251; Setra 730 capacitance manometers; Inficon PSG500, PSG550, Porter, SKY, Stripe, MAG, MPG and MPG400.
Our source documentation does not itemise which two specific sensors ship with this regulator configuration, so we do not state them. Confirm the sensor pair against your intended pressure range before ordering.
Frequently asked questions
How does FYRA regulate vacuum?+
Through throttle control on two valve ports, each with an upper and lower set point. The FYRA powers a 24 VDC valve directly - no external relay - opening it until the lower set point is reached, then closing it so the system leaks up to the upper set point. The gap between the two set points defines the control hysteresis: narrower gives tighter control but more valve cycling. Install the valve between pump and vessel, and the sensor near the vessel being controlled.
Can it vent or bleed rather than throttle?+
Yes. Bleed control can either deliver a specified flow rate into a chamber or hold a vacuum level by bleeding gas in. Starting the bleed opens flow at the set level; stopping it closes the bleed valve and isolates gas flow to the system.
What does the WiFi option change?+
It selects between part numbers DIGI-FYRA-VR and DIGI-FYRA-VR-WIFI. WiFi is a factory option on the FYRA platform; USB and 0-10 V analogue in and out are present on both builds.
Which sensors does FYRA support?+
DigiVac SEN-VGT500, SEN-775i and Quantum (SEN-DPP, SEN-DCP, SEN-DPCP); MKS Convectron 275071 (1/8 in NPT) and 275203 (KF16); Agilent FRG700, PCG-750, PCG700, 531, 536, 531 equivalent and PVG 500; Pfeiffer PKR251 and IKR251; Setra 730 capacitance manometers; and Inficon PSG500, PSG550, Porter, SKY, Stripe, MAG, MPG and MPG400. Our documentation does not itemise which two sensors ship with this specific regulator configuration - confirm the pair against your pressure range before ordering.
What valves can it drive?+
The Dinamo proportional valve, VacStable bleed valve, solenoid-type bellows and plunger valves, and 24 V valves drawing less than 24 W. The valve card supports up to two valves.
What are the power, units and certifications?+
Power 100-240 VAC 50/60 Hz. Selectable units are Torr, mbar, kPa, microns, millitorr, mmHg and hectopascal. Display is a 3.9 in touch screen, mounted bench top or on a pole. Listed certifications are UL, CE and CSA.
