What Are MCP Pressure Sensors?

MCP pressure sensors are microelectromechanical devices designed to measure pressure in absolute, gauge, or differential modes. They are a critical component in modern automation, control, and monitoring systems. These sensors convert pressure changes into electrical signals that can be easily processed by control units or monitoring systems.

Types of MCP Pressure Sensors

• Absolute Pressure Sensors (MCP Absolute): Measure pressure relative to a perfect vacuum. They are often used in environments where atmospheric pressure variation must be eliminated, such as aerospace, weather monitoring, and vacuum systems.
• Gauge Pressure Sensors (MCP Gauge): Measure pressure relative to ambient atmospheric pressure. These are common in automotive tire pressure monitoring, HVAC systems, and fluid control applications.
• Differential Pressure Sensors (MCP Differential): Measure the difference between two pressure points. They are widely used in filtration systems, air flow measurement, and industrial process control.
