Sensor | G1/4 Stainless Steel Body | 5V Ceramic Transducer

This water pressure sensor transmitter is made for monitoring water systems. It runs on 5V and comes in 0.5 MPa or 1.2 MPa ranges. The stainless steel body resists corrosion. This makes it a reliable industrial water pressure sensor for pumps, tanks, and irrigation lines. Features and Benefits - Specific 0.5 MPa or 1.2 MPa ratings - Gives precise measurements for common water pump systems (0.5 MPa is about 72 PSI). - Stable 5V DC operation - Fits easily with common microcontrollers and data acquisition boards that use a 5V logic level. - 316L stainless steel construction - Resists corrosion, good for constant contact with water, including seawater. - Linear voltage output signal - Lets you monitor pressure remotely and program control logic for pumps or alarms. Applications - Water Pump Control - Keep constant pressure in a well or booster pump system. - Irrigation Systems - Monitor pressure to make sure water is spread evenly across sprinkler zones. - Tank Level Monitoring - Can be used as a submersible pressure transducer to measure liquid depth in a water tank. Safety & Preparation Before connecting any pressure transducer, including this G1/4 Stainless Steel Body sensor, always ensure the power supply is off. Verify the compatible media for the sensor – this unit works with water, oil, fuel, gas, and air. Operating outside of these parameters could damage the transducer or lead to inaccurate readings. Handle the sensor carefully to avoid damage to the ceramic transducer element. Ensure your testing environment is clean and free from debris that could interfere with connections or sensor performance. Check Excitation Voltage The correct excitation voltage is crucial for the proper operation of a pressure transducer. This particular sensor has a 5V output signal, which typically implies it operates with a specific input voltage, often 5V or 10V, though the exact excitation voltage is not specified. Consult the manufacturer's data sheet for the precise excitation voltage required. Using an incorrect voltage can prevent the transducer from functioning or even cause permanent damage. A multimeter can be used to verify the output of your power supply before connecting it to the transducer. Test Output Signal (Zero Pressure / No Load) To understand how a pressure transducer works, it's essential to test its output at zero pressure. With no pressure applied to the G1/4 process connection, power on the sensor. This ceramic transducer should produce a baseline output signal. For a 5V output transducer like this one, you would expect a specific voltage at zero pressure. This baseline reading is important for calibrating your system and ensuring the transducer is functioning correctly before it's subjected to actual pressure. For Current Output Transducers (4–20 mA): While this specific sensor has a 5V output signal, current output transducers, such as those with a 4–20 mA range, operate differently. These transducers provide a current signal proportional to the applied pressure. A 4 mA output typically represents the lowest pressure point (e.g., 0 MPa), while 20 mA represents the maximum pressure (e.g., 1.2 MPa). They are often preferred for long cable runs due to their immunity to electrical noise. You would use an ammeter in series with the transducer to measure the output. For Voltage Output Transducers (0-5V, 0-10V, or mV): This sensor is a voltage output transducer with a 5V output signal. Other common voltage ranges include 0-10V or millivolt (mV) outputs. These transducers provide a voltage signal that corresponds to the applied pressure. For example, a 0-5V transducer might output 0V at 0 MPa and 5V at its maximum pressure (e.g., 0.5 MPa or 1.2 MPa, depending on the range). To test, connect a voltmeter across the output terminals of the transducer. The voltage reading will change as pressure is applied to the G1/4 connection.
