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 room with multiple extruder units running simultaneously. A small deviation in vacuum pressure could impact performance, but operators could not realistically watch every gauge at all times. They needed an unmistakable, facility-wide indication when action was required – both visual and audible – so issues could be addressed immediately.
The Solution: A Custom Fyra Vacuum Controller with Light Tower and Alarm
To meet this need, DigiVac engineered a custom solution built around the Fyra vacuum controller, configured specifically for alarm-based monitoring. The Fyra was paired with a 775i vacuum sensor and integrated into a rugged enclosure designed for easy installation on customer-provided struts.
At the core of the solution is simple, intuitive status indication:
- Green light: Vacuum pressure is within the acceptable range
- Red light + audible buzzer: Vacuum pressure is outside the defined limits
A red/green light tower mounted on top of the Fyra ensures visibility from nearly anywhere in the manufacturing room, while a side-mounted buzzer provides an audible alert that cuts through ambient noise. An arm/disarm switch on the front panel allows operators to quickly enable or disable alarms as needed during startup or shutdown.
Why Fyra: Flexible, Reliable, and Built for Control
The Fyra vacuum controller is well-suited for this application because it combines precision measurement with flexible control and I/O capability. For this configuration, the system includes:
- Fyra vacuum controller with the required drive card for the 775i sensor
- 775i sensor for accurate vacuum measurement
- 24 V throttle card to support system control needs
- Integrated light tower and audible alarm hardware
The customer’s target vacuum range was 15 to 18 inches of mercury, and the system was initially programmed to trigger alarms below 15” Hg and above 18” Hg. Importantly, these limits are user-settable, allowing the same unit to be reused for future projects or adjusted if process requirements change.
Simple Operation, Real Results
From an operator’s perspective, the workflow is intentionally minimal:
- Start the process
- Activate alarms
- Run the process
- Deactivate alarms
- Stop the process
This straightforward approach delivers exactly what the customer needed: a clear indication of system readiness and immediate feedback when something is wrong – without requiring constant attention.
A Practical, Scalable Alarm Solution
By leveraging the flexibility of the Fyra vacuum controller and integrating highly visible and audible alarms, DigiVac delivered a dependable, ready-to-use solution tailored to the customer’s environment. Mounted on a pipe stack and visible across the production floor, the system reduces operator workload, minimizes response time, and simplifies vacuum monitoring in a demanding manufacturing setting.
For customers who need reliable vacuum oversight without unnecessary complexity, this custom Fyra alarm configuration demonstrates how targeted engineering can turn a simple requirement into a highly effective solution.
