Technical Specifications
Product Overview
Large diameter earth pressure cell for foundation and embankment monitoring.
Working Principle
Pressure transducers convert fluid pressure into proportional electrical signals using strain gauge, piezoresistive, or capacitive sensing elements. The sensing element deforms under applied pressure, producing a measurable change in electrical properties. Strain gauge designs bond multiple gauges to a metal diaphragm in a Wheatstone bridge configuration for enhanced sensitivity and temperature compensation. Piezoresistive sensors integrate the sensing elements directly into a silicon diaphragm for compact size and high performance. Advanced signal conditioning provides amplification, linearization, and temperature compensation, delivering accurate measurements across wide pressure and temperature ranges.
Application Scenarios
Critical for process control, hydraulic system monitoring, and safety instrumentation across industries. Extensively used in chemical processing, oil & gas production, water treatment, and manufacturing automation. Essential for monitoring pipeline pressures, controlling pneumatic systems, and protecting equipment from overpressure conditions. The sensor supports applications requiring precise pressure measurement for quality control, efficiency optimization, and regulatory compliance. Particularly valuable in applications with aggressive media, high temperatures, or demanding accuracy requirements.
Technical Advantages
Provides accurate and stable pressure measurement with excellent long-term stability and minimal drift. Wide pressure range options from vacuum to ultra-high pressure accommodate diverse applications.
