Range Pressure Sensor | 5-300 PSI Ceramic Core | G1/4 for Water & Oil

This pressure sensor measures water, oil, fuel, or air. Its stainless steel body and G1/4 port resist corrosion and connect easily. The ceramic core gives stable readings across a 5-300 PSI range. It's a useful pressure transducer for many projects. Features and Benefits - Stainless steel body and G1/4 port - Resists corrosion from fuel or water; fits common connections. - Ceramic sensor core - Gives stable, accurate readings that don't drift much with temperature changes. - 5-12V operating voltage - Lets you use it with various automotive or industrial electronics. - Multiple pressure ranges (5-300 PSI) - Choose the right pressure transmitter for your task, from low-pressure air to higher-pressure hydraulics. Applications - Automotive Systems - Monitor fuel or oil pressure to find engine issues. - Industrial Controls - Manage air pressure in pneumatic tools or water pressure in processing lines. - HVAC Equipment - Check refrigerant levels or system pressure for diagnostics and maintenance. Safety & Preparation Before commencing any work on the Range Pressure Sensor, ensure all power sources are disconnected to prevent electrical hazards. Verify that the system you are connecting the sensor to is depressurised and drained of any medium. This prevents accidental spills or high-pressure releases. Always wear appropriate personal protective equipment, such as safety glasses and gloves, especially when handling tools or working with oils and fuels. Work in a well-ventilated area. Check Excitation Voltage The Range Pressure Sensor requires an input voltage of 5-12V. Before connecting, use a multimeter to verify that your power supply provides the correct voltage within this range. Applying an incorrect voltage can damage the transducer. Ensure the polarity is correct when connecting the power supply to avoid damaging the internal ceramic sensor. This step is crucial for the proper functioning and longevity of the pressure transducer. Test Output Signal (Zero Pressure / No Load) To understand how the pressure transducer works, it's helpful to test its output at zero pressure. With the sensor connected to its 5-12V input voltage but not under any pressure, measure the output signal. For a voltage output transducer, this will be a specific voltage (e.g., 0V or 0.5V). For a current output transducer, this will be a specific current (e.g., 4 mA). This baseline reading is essential for accurate calibration and troubleshooting. For Current Output Transducers (4–20 mA): If your Range Pressure Sensor is a 4–20 mA output type, connect a multimeter in series with the output loop. With no pressure applied, the multimeter should read approximately 4 mA. As pressure increases within the 5-300 psi range, the current output will rise proportionally, reaching 20 mA at the maximum rated pressure. This linear response is how the transducer converts physical pressure into an electrical signal for a logic controller or display. For Voltage Output Transducers (0–5V, 0–10V, or mV): For voltage output transducers (e.g., 0–5V, 0–10V, or mV), connect a multimeter in parallel across the output terminals. At zero pressure, you should observe the low-end voltage output (e.g., 0V or 0.5V, depending on the specific model). As pressure is applied to the G1/4 connection, the voltage will increase linearly up to the high-end voltage (e.g., 5V or 10V) when the sensor reaches its 300 psi maximum. This voltage change provides a direct reading of the applied pressure.
