OMEGA’S high accuracy PX409 Series Pressure Transducers have a proven record in high-performance commercial and aerospace applications for over 25 years. A full Wheatstone bridge is diffused into a silicon wafer and then micro-machined to exacting standards to produce a silicon sensor that has excellent stability, linearity, repeatability, and excellent long-term stability. At our state-of-the-art facilities, transducers are calibrated using extremely high accuracy equipment, and a 5-point NIST traceable calibration certificate is included with each model. All Stainless Steel wetted parts, welded construction and premium temperature compensation makes transducers suitable for use in tough industrial environments. OMEGA’s free downloadable Software provides advanced data logging capabilities hence add value and flexibility to your transducer performance.

Build/Order/Ship OMEGA’S MM Series Custom Pressure Transducers to meet your pressure sensing requirements:  As a lead pressure transducer manufacturer, Omega has developed a new interactive configuration tool that provides a fast and simple way to build custom transducer suitable for application. MM Series custom transducers allow for over 1-million possible combinations of parameters such as pressure type, range, unit, material, output, accuracy, fitting, temperature compensation range, and electrical termination.  At the end of the process, the Configurator will provide a part number, price and delivery time for the transducer.

Some of the most Popular Applications  of Pressure Transducers include: 
  • Measuring inlet, outlet, or system pressure in engine test setup
  • Measuring pressure drops in a line for preventive maintenance
  • Measuring fluid height or level in tanks
  • Measuring a water pipe leak or gas leak and monitoring gas pressure
  • Maintaining pressure in food and beverage lines
  • Sanitary pressure  measurement  in the bio or pharmaceutical industry.
  • For Intrinsically Safe and CSA ratings see model PX509-IS .

     

    What is the accuracy of the PX409 Series?

    The PX409 Series has a high accuracy of ±0.08% BSL and includes linearity, hysteresis, and repeatability. To obtain their high accuracy and stability, the PX409 Series uses state-of-the-art digital mapping of the temperature, pressure, and output performance of the silicon sensor in conjunction with a custom ASIC to provide dynamic thermal compensation across the temperature and pressure parameters.

    Is the PX409 Series suitable for any liquid and gas applications?

    OMEGA piezoresistive pressure transducers have a proven record in high performance commercial and aerospace applications for over 25 years. The piezoresistive process and the construction of the PX409 Series provides a very rugged transducer with exceptional accuracy, stability, and thermal effects. The PX409 Series is all stainless steel (316 SS) wetted parts. Please ensure the media under measurement is compatible with wetted parts.

    What is the power supply for the PX409 Series?

    The power supply of the PX409 Series depends on the output of the chosen model and power supply fluctuation protection is standard on all models. Please refer to the table below for details.

    Output Model

    Power Supply

    0 to 5 Vdc

    10 to 30 Vdc@10 mA

    0 to 10 Vdc

    15 to 30 Vdc@10 mA

    4 to 20 mA

    9 to 30 Vdc

    10 mV/V

    Ratiometric 5 to 10 Volts DC

    Is the PX409 Series calibrated?

    The Px409 Series are calibrated using extremely high accuracy equipment and a 5-point NIST traceable calibration certificate that is included with each transducer. It is recommended that the sensor be recalibrated once a year. The most popular ranges and configurations are stocked for immediate delivery. All others typically have a very short lead-time.

    How can I install a PX409 Series in a pipe? Does it need a specific orientation (vertical or horizontal)?

    The PX409 Series has a ¼ - 18 NPT male fitting that is threaded into a pipe fitting for installation. There is no specific orientation needed – the unit is calibrated in the vertical direction with fitting down. The sensor is designed to be quickly customized to meet your exacting specifications, often with fast delivery.
