G1/4 Industrial Pressure Sensor | 0-10 Bar Range | 4-20mA Output Transmitter

This G1/4 pressure sensor works in industrial and commercial systems that measure oil, water, or gas pressure. It comes in several common ranges, including 1 bar and 5 bar. You can also choose the output signal you need, such as 4-20mA, 0-10V, or RS485. Features and Benefits - Flexible output signals - Available as a 4-20mA pressure transmitter for long cable runs or a 0-10V pressure sensor for local controllers. - Stainless steel body and G1/4 thread - Gives you a secure, corrosion-resistant connection for many industrial applications. - Specific pressure ranges - Select a low-range sensor, like a 1 bar pressure sensor for vacuum, or a 0-5 bar model for light hydraulics. - Measures various media - Designed to accurately read the pressure of non-corrosive gases, oil, and water. Applications - Hydraulic systems: A 0-5 bar pressure sensor is a good fit for monitoring pressure in low-force hydraulic circuits. - Water management: Use a G1/4 pressure sensor with a 4-20mA output to monitor water line pressure from a central control room. - Pneumatics: Check the pressure in compressed air systems to make sure tools and machinery operate correctly. Safety & Preparation Before commencing any work on pressure sensing systems, ensure all relevant safety protocols are observed. This includes depressurising systems and isolating power sources where necessary. Pressure transducers like this one are designed to measure pressure in various mediums, including oil, water, and gas. Understanding how a pressure transducer works involves converting applied pressure into an electrical signal. Always ensure you have the correct tools and a multimeter for testing. Check Excitation Voltage The transducer requires an excitation voltage to operate. This is typically 24V DC for industrial applications, but some models may use 5V or 10V. Consult your system documentation or the transducer's general specifications for the required voltage. Use a multimeter to verify the excitation voltage at the transducer's terminals before connecting the device. An incorrect voltage can damage the internal strain gauge or other components. Test Output Signal (Zero Pressure / No Load) To understand how pressure transducers work, it is important to test their output at known conditions. With no pressure applied (zero pressure or no load), the transducer should output its minimum signal. For a 4-20mA output, this would be 4mA. For a 0-10V output, this would be 0V. Use a multimeter to measure the output signal. This baseline measurement is crucial for calibrating and troubleshooting the sensor. For Current Output Transducers (4–20 mA): This G1/4 Industrial Pressure Sensor offers a 4-20mA output. To test, connect a multimeter in series with the output loop. With zero pressure, you should read approximately 4mA. As pressure increases within the 0-10 Bar range, the current output will increase proportionally, reaching 20mA at 10 Bar. This linear relationship allows a logic controller or other monitoring device to accurately interpret the measured pressure. Ensure your multimeter is set to measure current (mA). For Voltage Output Transducers (0–5V, 0–10V, or mV): While this specific product offers 4-20mA, it also has options for 0-10V and 0.5-4.5V outputs. For voltage output transducers, connect a multimeter in parallel across the output terminals. At zero pressure, the output should be 0V for a 0-10V transducer, or 0.5V for a 0.5-4.5V transducer. As pressure increases, the voltage will rise proportionally up to the maximum output (e.g., 10V at 10 Bar). Ensure your multimeter is set to measure DC voltage.
