Minimizing Circuit Board Strain Propagation in Surface Mounted Pressure Sensors
Milled PCB isolation slots and controlled solder standoff heights decouple surface mount pressure sensors from assembly flexure and thermal board strain.
Pressure Sensor
Transduction Mechanism
An industrial instrument that converts a physical force exerted by a gas or liquid into an electrical signal provides the essential data required for process monitoring and control. This device, known as a pressure sensor, detects the mechanical deflection of a flexible diaphragm or sensing element. The physical deflection is converted into a measurable electrical property such as resistance, capacitance or voltage, which is then processed by transmitter electronics into a standardized output signal.
Technology Type
Sensing elements utilize different electronic technologies to achieve the required accuracy, response time and temperature stability. Choosing a piezoresistive pressure sensor is common for dynamic applications, while capacitive designs offer superior stability and precision for low pressure measurements. Each technology has unique advantages that make it suitable for specific environmental and process conditions.
Industrial Application
Integration into complex systems requires careful consideration of mounting configurations, electrical connections and process seals. A robust pressure sensor is used in applications ranging from hydraulic systems to process piping and storage vessels. These instruments prevent overpressure events and optimize process efficiency.
Performance Parameter
Key characteristics like linearity, hysteresis and thermal drift define the overall capability of the measuring instrument. Selecting a pressure sensor requires matching these performance parameters to the requirements of the process loop. This careful selection prevents excessive measurement uncertainty and maintains system safety.
