Pressure Sensors

What are Pressure Sensors?

Pressure sensors convert the force of a fluid or gas into an electrical signal that can be monitored, recorded, or used to trigger control actions. They’re one of the most widely used measurement devices in industrial processes — found in everything from hydraulic systems and pneumatic equipment to chemical reactors, pipelines, and HVAC systems. The right pressure sensor gives you the data you need to keep processes running safely, efficiently, and within spec.

Pressure measurement comes in several flavors: gauge pressure (relative to atmosphere), absolute pressure (relative to vacuum), differential pressure (between two points), and sealed pressure (relative to a fixed reference). Selecting the right type, pressure range, accuracy class, and output signal is critical to getting reliable measurement for your application. At Process Solutions Corp., we help you navigate the options and select sensors that match your media, environment, and performance requirements.

Why Reliable Pressure Measurement Matters

• Process Safety — Detect overpressure conditions before they become hazards
• Equipment Protection — Monitor system pressure to prevent damage to pumps, valves, and vessels
• Quality Control — Maintain consistent pressure for repeatable process results
• Energy Efficiency — Optimize compressor and pump performance with accurate pressure data
• Regulatory Compliance — Meet documentation requirements for pressurized systems

Common Pressure Sensor Types

• Gauge Pressure Sensors — Measure pressure relative to ambient atmospheric pressure
• Absolute Pressure Sensors — Measure pressure relative to a perfect vacuum reference
• Differential Pressure Sensors — Measure the difference between two pressure points
• Sealed Gauge Sensors — Reference a sealed atmospheric pressure for stable readings at altitude
• Submersible Level Sensors — Pressure-based level measurement for tanks and wells
• High-Purity / Sanitary Sensors — Specialized designs for pharma, food, and semiconductor applications
