Transducer with Ceramic Sensor | 5-300 PSI | 1/8NPT Stainless Body

This pressure transducer combines a sensor, transducer, and transmitter into one unit. It measures water, oil, fuel, or gas. The core is a ceramic sensor for accuracy, housed in stainless steel with a 1/8" NPT thread. It accepts a 5-16V input and provides a proportional output signal. Features and Benefits - Ceramic pressure sensor core - Gives you a stable reading that's less affected by temperature shifts and vibration. - Wide pressure selection (5-300 psi) - Choose the range that matches your needs, from a fuel pressure sensor to a water pump monitor. - 1/8" NPT stainless steel fitting - Installs easily and holds up against different fluids without corroding. - Broad 5-16V input voltage range - Works with the varied power supplies found in automotive, marine, and industrial settings. Applications - Automotive diagnostics: Use it as a fuel pressure sensor to verify fuel pump and regulator function. - Residential or commercial plumbing: Install it as a water pressure sensor to monitor supply line pressure. - HVAC and compressed air: A good choice for a gas pressure sensor to check for consistent pressure in pneumatic lines. Safety & Preparation Before commencing any work on your transducer, ensure that the system is de-energised and depressurised. Pressure transducers convert physical pressure into an electrical signal, and incorrect handling can lead to damage or inaccurate readings. Always wear appropriate personal protective equipment. Handle the transducer carefully, avoiding dropping or subjecting it to harsh impacts, as this can affect the ceramic sensor's accuracy. Verify the process connection of 1/8 NPT is clean and free from debris before installation. Check Excitation Voltage The transducer requires an input voltage, also known as excitation voltage, to operate. For this transducer, the input voltage range is 5-16V. Before connecting the transducer to your system, use a multimeter to verify that the power supply provides a stable voltage within this specified range. Providing an incorrect voltage can damage the transducer's internal electronics. Ensure the wiring is correct according to the manufacturer's instructions for positive and negative terminals to prevent polarity issues. Test Output Signal (Zero Pressure / No Load) To test the transducer's functionality, connect it to the appropriate power supply within the 5-16V input range. With no pressure applied (zero pressure or no load), measure the output signal. The expected output will vary depending on whether it is a current output (e.g., 4-20 mA) or a voltage output (e.g., 0-5V, 0-10V, or mV). This baseline reading helps confirm the transducer is operational before full system integration. For Current Output Transducers (4–20 mA): This specific transducer's output type is not specified. If it were a current output transducer, with no pressure applied, the output should typically be 4 mA. You would connect an ammeter in series with the transducer's output to measure this current. As pressure is applied within the 5-300 psi range, the current output would proportionally increase, reaching 20 mA at the maximum pressure. This signal can then be read by a logic controller or other monitoring equipment. For Voltage Output Transducers (0–5V, 0–10V, or mV): This specific transducer's output type is not specified. If it were a voltage output transducer, with no pressure applied, the output should typically be 0V, 0.5V, or a specific mV reading depending on the transducer's design. You would connect a voltmeter in parallel across the transducer's output terminals to measure this voltage. As pressure is applied within the 5-300 psi range, the voltage output would proportionally increase, reaching the maximum specified voltage at the full pressure.
