Differential Pressure Gauges and Differential Pressure Switches for HVAC and Industrial Control
If you’ve ever tried to keep a complex HVAC or process system running smoothly, you already know that the smallest details often make the biggest difference. That’s where differential pressure gauges and differential pressure switches come into play. At Peak Amp Instruments, we offer tools that give you real-time visibility into what's happening between two points. No guesswork, no unnecessary system stress.
These gauges aren’t just display pieces. They’re workhorses, helping you monitor and control pressure differences across filtration systems, airflow lines, and other equipment. The ability to control pressure differences accurately allows technicians to catch problems before they escalate.
Digital Differential Pressure Gauges Bring Modern Functionality
Analog tools have their charm, but digital differential pressure gauges bring a whole new level of convenience to the job site. With clear, backlit displays and features like programmable units, alarm outputs, and data storage, these instruments simplify both diagnostics and compliance logging. They're especially valuable in lab systems and testing environments where precise readings are not a luxury but a necessity.
You might see benefits in systems where pressure differences in industrial processes need to be monitored throughout the day. These differential pressure gauges often operate alongside transmitters to deliver information remotely. Used in commercial or industrial projects, they add clarity when tracking flow rate, liquid levels, or absolute pressure. Our differential pressure gauges and differential pressure switches help you monitor and control.

Differential Pressure Gauges for Process Filters Reduce Risk and Boost Maintenance Timing
Clogged filters are a silent killer in many systems, slowly eating away at energy efficiency. That’s where process filter gauges earn their keep. They track the difference in pressure across a filter, helping you identify rising resistance and time your maintenance just right. Instead of running a system to failure or changing filters too early, these gauges help strike that perfect balance.
Used in food processing, clean rooms, and pharmaceutical systems, filter gauges improve both safety and reliability. The pressure drop across the pipe or filter is displayed clearly, giving maintenance teams the kind of actionable data that keeps systems smooth and downtime low. Plus, with heavy duty options available, you can keep them in play even under intense operating conditions.

Differential Pressure Switches Automate Reaction Points
A differential pressure switch doesn't just observe, it acts. Designed to monitor and control pressure between two locations, these switches are used when you need immediate feedback from changing conditions. For example, when air filters begin to clog and the pressure differences increase, these switches monitor and control the process by sending alerts or engaging relays.
Whether you're in HVAC, medical filtration, or pump operations, differential pressure switches monitor key thresholds and help protect equipment. Used properly, they can automate fan speed changes, stop a system before damage occurs, or activate an alarm when readings go beyond safe ranges. In other words, they serve as a built-in decision-maker, reducing the need for constant oversight.
Pressure Switches Offer Reliable Control in Broader Applications
Looking beyond differential models, general-purpose pressure switches still serve as backbone components in many commercial and industrial settings. Used to activate circuits when reaching a maximum pressure or hitting a setpoint, these switches play a central role in systems managing air pressure, water supply, or hydraulic movement. Differential pressure control switches offer more customization and reliability.
They’re frequently found paired with electronic controllers and other equipment for automated system responses. With options that range from compact enclosures to high-load relays, these switches are built to meet a wide range of industry needs. When chosen wisely, they offer reliable performance that helps extend the life of your core equipment and streamline your maintenance cycles.
Product Options That Suit Every Professional Level
From boots-on-the-ground contractors to facility planners making high-level decisions, Peak Amp Instruments supports every phase of monitoring and control. Whether you need a differential pressure gauge to measure airflow in a rooftop unit or a differential pressure switch to monitor pressure changes in a chemical process, our lineup offers the right match.
