Automated Roughing-to-Turbo Crossover

Automated Roughing to Turbo Crossover Application Note — SNAP Cart Mode Achieving High Vacuum Control with SNAP Your process starts at atmosphere and needs to reach a vacuum level deeper than a roughing pump can deliver on its own. The standard approach is to rough the chamber down with a backing pump, then bring a turbomolecular pump online once the pressure is low enough for the turbo to take over efficiently. Done by hand, this means watching a gauge and switching valves at just the right pressure — on every cycle. SNAP Cart mode automates that handoff, so the transition

FYRA Configuration Guide: Driver Cards, Functions, and System Compatibility

FYRA Configuration Guide: Driver Cards, Functions, and System Compatibility The DigiVac FYRA Controller is designed with a modular structure that supports up to six installed cards, allowing users to tailor the system to their applications. These slots can be populated with a combination of sensor cards, valve driver cards, and relay functionality, depending on the level of measurement and control required. For example, a typical configuration might include three sensor cards for pressure monitoring, two valve cards for control, and one relay (integrated on a valve or dedicated card) to interface with external equipment. This flexibility enables FYRA to function

FYRA for End of Primary Drying Detection | Vacuum Drying Monitoring

FYRA for End of Primary Drying Detection | Vacuum Drying Monitoring What is Fyra End of Drying? The FYRA for End of Primary Drying Detection is a bundle that assists in detecting when most of the water or residual solvent from a product has been removed or the end of primary drying has been reached in a vacuum drying application. This bundle includes the FYRA vacuum controller paired with a DPCP Quantum sensor, a KJL 275 Convection-enhanced Pirani Gauge, and a Convection enhanced gauge cable. The DPCP Quantum sensor can measure a range from 10^(-5)Torr to 1000 Torr, while the KJL 275 has a range of 0.1mT to 1000 Torr. How

ATaPsi: Integrated Vacuum and Temperature Control for Vacuum Ovens & Furnaces

ATaPsi: Integrated Vacuum and Temperature Control for Vacuum Ovens & Furnaces What is ATaPsi? ATaPsi — Automated Temperature and Pressure with a Single Interface — is an advanced process control solution designed to unify vacuum and temperature control within vacuum ovens and vacuum furnaces. By integrating the DigiVac SNAP vacuum controller with the Eurotherm 3204 temperature controller, ATaPsi allows operators to monitor, control, automate, and log both process variables from a single interface. The result is improved repeatability, reduced operator intervention, and greater visibility into thermal vacuum processes. Originally developed for pharmaceutical manufacturing applications requiring secure process documentation and synchronized

How a Custom Calibration Cart Streamlined Vacuum Gauge Validation

How a Custom Calibration Cart Streamlined Vacuum Gauge Validation Custom Vacuum Calibration Cart for In-House Validation of Capacitance Manometers Applications Many vacuum processes rely on accurate sensor readings. However, calibration often requires sending gauges off-site, which causes delays and downtime. DigiVac received an inquiry from a customer who operates in medium to high vacuum environments and needed to replace an discontinued calibration cart. Their application required calibration of 2 Torr, 100 Torr, and 1000 Torr capacitance manometers. To solve this, DigiVac designed a custom vacuum calibration cart. This turnkey system allows for in-house calibration and validation, improving efficiency and reducing

Time-Based Vacuum Differential Control with SNAP

SNAP External Valve Control Option The SNAP vacuum controller uses Time-Based Vacuum Differential Control to actively optimize vacuum performance. It regulates an external valve based on real-time vacuum differentials (VD) within a defined time window (VDW), helping the system reach setpoints faster and more reliably. How It Works The controller continuously compares the current vacuum level to the setpoint. If the system fails to reach the required differential within the defined time, it opens the external valve. It then modulates the valve as needed to quickly drive the system to the target vacuum. Configuration Set up Time-Based Vacuum Differential Control

How to Achieve Stable Vacuum Control with Automated Valve Sequencing

Automated Valve Control for Precision Vacuum Systems The Challenge A customer required a reliable way to automate valve sequencing across a complex vacuum system using electromagnetic and pneumatic valves. Maintaining stable chamber pressure while coordinating multiple valves – without constant operator input – created risk in consistency, timing, and overall system performance. The Solution DigiVac delivered an intelligent control architecture built around two FYRA Vacuum Controllers, each equipped with quad solid-state relay capability for synchronized valve actuation. The FYRA platform is a highly configurable vacuum control instrument capable of driving multiple sensors and valves simultaneously. This makes it ideal for

Protecting Multi-Tool Vacuum Processes with Visual Pressure Alerts

Protecting Multi-Tool Vacuum Processes with Visual Pressure Alerts A Simple, Visual Solution to Protect Process Uptime When multiple tools share a single vacuum pump, maintaining stable foreline pressure is critical. In one recent application, a customer was operating five tools connected to a single vacuum pump, all of which function reliably below 558 Torr but become inoperable if pressure rises above that threshold. The challenge was clear: the customer needed a dependable, easy-to-use control solution that would prevent over-pressure conditions while giving operators immediate visibility into system status. DigiVac delivered a purpose-built solution that combined intelligent pressure control, clear visual

Fyra in Action: A Simple Vacuum Alarm Solution for Busy Manufacturing Floors

Simplifying Vacuum Monitoring with Smart, Visual Alarms Using the DigiVac Fyra In high-throughput manufacturing environments, operators are often responsible for monitoring multiple systems at once. When vacuum integrity is critical to product quality and process stability, relying on constant manual checks is inefficient and risky. One DigiVac customer faced this exact challenge and came to us looking for a straightforward solution: a vacuum gauge that could clearly alert operators when vacuum levels drifted outside an acceptable range, without adding complexity to their workflow. The Challenge: Clear, Immediate Vacuum Alerts in a Busy Production Space The customer operates a large manufacturing

Simple Vacuum Pump Testing Made Easy

Diagnose Pump Performance in Minutes with the Right Tools When your vacuum system underperforms, every second counts. The fastest way to identify the problem is simple: test your vacuum pump directly. With the right gauge and a quick setup, you can determine pump health in under a minute – saving time, reducing downtime, and improving process reliability. DigiVac makes that process effortless with dependable, precision instruments designed for accurate pump diagnostics. Why Start with the Pump? Your entire vacuum system depends on one thing: your pump’s ability to achieve its ultimate pressure. If your process requires 400 microns, but your
