Pressure Transducer | 0.5-4.5V Output | For Oxygen Generators

The XGZP6847A is a piezoresistive sensor. It measures pressure in non-corrosive gas or air. It sends a 0.5-4.5V analog output that is already calibrated and temperature-adjusted. This sensor comes in several pressure ranges, from -100kPa to 700kPa, to fit what you need. Features and Benefits - Ratiometric Analog Output - The 0.5-4.5V output changes with the power supply voltage. This helps reduce errors from power changes. - Piezoresistive Silicon Chip - This main part of the sensor reacts evenly and directly to pressure changes. - Temperature Compensated - It's set up to work accurately across a wide temperature range. This keeps measurements correct in different conditions. - Multiple Range Options - Pick from several pressure ranges. This gives you the best detail for your project. Applications - Watching pressure in oxygen generators and medical devices - Controlling airflow and pressure in heating and cooling systems - Monitoring pneumatic tools and industrial processes Safety & Preparation Before working with any electrical components, always ensure the power supply is disconnected. Wear appropriate personal protective equipment, such as safety glasses, to prevent injury. Ensure your work area is clean and well-lit. When handling the pressure transducer, avoid dropping it or subjecting it to sharp impacts, as this can damage the internal resistance sensor. Always refer to the manufacturer's instructions for specific safety guidelines related to your power supply and measurement equipment. Check Excitation Voltage The pressure transducer requires an excitation voltage to operate. For this specific pressure transducer, the output signal is 0.5-4.5V DC, which typically indicates it operates within a 5V supply system. Before connecting the transducer, verify that your power source provides a stable voltage within the recommended operating range. Using an incorrect excitation voltage can damage the transducer or lead to inaccurate readings. Use a multimeter to confirm the voltage output of your power supply before making any connections. Test Output Signal (Zero Pressure / No Load) To test the pressure transducer, connect it to a stable power supply. For this 0.5-4.5V output model, apply the appropriate excitation voltage. With no pressure applied (ambient pressure), measure the output signal using a multimeter. For a 0.5-4.5V output pressure transducer, you should expect to see an output close to 0.5V DC at zero pressure, although slight variations may occur due to environmental factors or calibration. This initial reading confirms the transducer is powered and providing a baseline signal. For Current Output Transducers (4–20 mA): This section is not applicable to the Pressure Transducer | 0.5-4.5V Output | For Oxygen Generators, as its specified output signal is 0.5-4.5V DC, not 4-20 mA. Current output transducers typically generate a 4-20 mA signal proportional to the measured pressure. To test them, connect a multimeter in series with the transducer and power supply. At zero pressure, you should read approximately 4 mA. As pressure increases, the current output should rise, reaching 20 mA at the maximum specified pressure. For Voltage Output Transducers (0–5V, 0–10V, or mV): The Pressure Transducer | 0.5-4.5V Output | For Oxygen Generators is a voltage output transducer. To test it, connect the transducer to its appropriate excitation voltage. Connect a multimeter in parallel across the output terminals. At zero pressure, you should observe an output close to the specified minimum voltage, which is 0.5V DC for this model. As pressure is applied within the specified ranges (-100-0 kPa, 0-100 kPa, 0-200 kPa, 0-500 kPa, 0-700 kPa), the voltage output should increase proportionally, reaching 4.5V DC at the maximum specified pressure.
