Pressure Sensor | 4-20mA Transmitter | G1/4 Stainless Steel

This industrial pressure sensor measures the pressure of water, oil, fuel, or air and converts it into a stable electrical signal. It outputs a standard 4-20mA current. This makes it easy to connect to your existing control systems and PLCs. Features and Benefits - Stainless Steel Body - The housing resists corrosion from common industrial fluids. It's a dependable fluid pressure sensor for oil and gas. - Multiple Pressure Ranges - Options are available from 0 up to 600 bar. You can choose the right pressure transducer for low-pressure air or high-pressure hydraulic systems. - Standard G1/4 Connection - The common thread size simplifies installation into existing ports, pumps, and pipelines. You won't need special adapters. - 4-20mA Current Output - This signal type is the industry standard for process control. It allows for clear communication with monitoring equipment over long cable runs. Applications - Hydraulic and Pneumatic Systems: Monitor line pressure in real time. This ensures machinery operates within safe limits. It also helps detect leaks or blockages. - HVAC and Water Management: Use it to track water pump output, boiler pressure, or air pressure within commercial building control systems. - Automotive and Engine Testing: Install this pressure sensor to measure oil, fuel, or coolant pressure. It helps with diagnostics and performance tuning. Safety & Preparation Before installing or testing any pressure sensor, ensure the system is depressurised and isolated from power sources. Always wear appropriate personal protective equipment, such as safety glasses. Verify that the media compatibility of the pressure sensor (Water, Oil, Fuel, Gas, Air for this model) matches the application to prevent damage or hazardous leaks. Ensure all connections are secure and free from contaminants. Incorrect installation can lead to inaccurate readings or component failure. Check Excitation Voltage The pressure sensor requires an operating voltage between 12-36V. Before connecting the sensor, use a multimeter to verify that your power supply provides the correct voltage within this range. An incorrect excitation voltage can damage the transducer or lead to inaccurate output readings. For 4-20mA transmitters like this one, it's crucial to supply stable DC power. Fluctuations in the supply voltage can affect the accuracy of the output signal, compromising the reliability of your pressure measurements. Test Output Signal (Zero Pressure / No Load) To test the pressure sensor, connect it to the appropriate power supply (12-36V). Before applying any pressure, measure the output signal. For this 4-20mA transmitter, the output should be at its minimum, typically 4mA, when there is no pressure applied. This 'zero pressure' reading confirms the basic functionality of the pressure transducer. Any significant deviation from 4mA at no load may indicate a fault with the sensor or the testing setup. For Current Output Transducers (4–20 mA): This pressure sensor is a 4-20mA transmitter. To test its output, connect a multimeter in series with the power supply and the sensor to measure the current. At zero pressure, you should read approximately 4mA. As pressure is applied within the 0-600 bar range, the current output should increase proportionally, reaching 20mA at the maximum rated pressure. This linear relationship is how the pressure transducer converts physical pressure into an electrical signal for a logic controller or display. For Voltage Output Transducers (0–5V, 0–10V, or mV): (This section is not applicable to the "Pressure Sensor | 4-20mA Transmitter | G1/4 Stainless Steel" as it has a 4-20mA output signal, not a voltage output. For voltage output transducers, you would connect a multimeter in parallel across the output terminals to measure the voltage, which would typically range from 0-5V or 0-10V depending on the specific model and its specifications.)
