Pressure Sensors, Transducers

Pressure sensors, transducers, also known as pressure transmitters, are electronic devices designed to measure pressure against a reference. Among the most used types are capacitive, piezoelectric, and resistive sensing elements. The U5254-000002-014BA is a capacitive pressure sensor transducer that measures absolute and differential pressure ranges of up to 50 kPa.

Overview

The U5254-000002-014BA is a silicon-on-insulator (SOI) based capacitive system pressure transducer from Dytran Instruments. It is designed to measure differential or absolute pressure ranges up to 50 kPa, with a static accuracy of 0.08%. It features an industry standard mount design, and a wide operating temperature range of -20°C to 125°C. The U5254-000002-014BA is available in either analog or digital output, and is protected from over-pressure (up to 200 kPa) and shock up to 500 g.

• Interface: mV/V or Wetted Sensors

Applications

The U5254-000002-014BA is a low-cost, high-performance pressure transducer specifically designed for use in a wide variety of automotive applications. It offers accurate real-time measurement of pressure at a wide range of temperatures, and is an excellent choice for dynamic performance testing of automotive systems such as power steering, suspension, turbochargers, and brakes. The U5254-000002-014BA is also suitable for industrial applications such as oil and gas pressure sensing, HVAC systems, process control, and automatic inspection systems.

Working Principle

The U5254-000002-014BA pressure transducer utilizes a capacitive sensing element to measure pressure. In a capacitive sensor, a flexible membrane is used to create a variable capacitor. When pressure is applied to the membrane, it deforms and changes the capacitance measurement. This change is measured by an oscillator circuit, which produces an output signal proportional to the applied pressure. The output can be measured in mV/V, digital, or wetted sensors, depending on the application requirements.
