Pressure Sensors / Detectors / Transducers
Pressure Transducers are useful in oil well logging tools.
Press Release Summary:
Measuring 0.75 in. dia, OMEGADYNE® Series PX3400 features pressure ranges up to 20,000 psi. Model PX3425 operates to 250°F, while Model PX3435 operates up to 350°F. Transducers utilize thin-film strain gages, sputter deposited on vacuum-remelted, 17-4 PH stainless steel diaphragm. Heat sink effect of diaphragm and high bridge resistance reduce gage self-heating. Built-in RTD provides data to correct temperature effects with external microprocessor.
Original Press Release:
PX3400 Series Thin Film Pressure Transducer for Oil Well Logging Tools
The OMEGADYNE® PX3400 Series Pressure Transducers have earned a reputation for high performance, reliability and stability in tough, real-world applications. The PX3400 Series is particularly useful in deep well tools.
They have a narrow body diameter of 0.75" (19mm) and pressure ranges up to 20,000 psi (1,400 bar). Two models are available, PX3425 operates up to 121°C (250°F) and the high temperature PX3435 which operates up to 177°C (+350°F). These outstanding transducers use OMEGADYNE's advanced sputtered thin-film sensor technology. Thousands of the PX3400 Series transducers are used for oil well logging throughout the world. Stability is critical. A transducer that shifts during a logging cycle invalidates costly data. The OMEGADYNE® PX3400 Series transducer uses thin-film strain gages, sputter deposited on a metal diaphragm. This advanced-technology gage system provides superior stability, especially at high temperatures often found in oil wells. The diaphragm is machined from vacuum remelted 17-4 PH stainless steel with elaborate annealing, aging and stress relieving processes to insure a stable system. The gaged diaphragm design minimizes the number of components and welds in the transducer, increasing the reliability and precision of your logging data. The heat sink effect of the diaphragm, and the high bridge resistance reduce gage self-heating, decrease warm up time and conserve battery power. A built in Platinum resistance temperature element (RTD) provides data to correct temperature effects with an external microprocessor. OMEGADYNE's PX3400 series transducer can be modified to meet your design requirements. A broad selection of optional features are available.
Price Starts at $1395.
