Precision Pressure Instrumentation & Custom Transducers
Capabilities: Since 1951, Paine Electronics has manufactured state-of-the-art precision pressure instrumentation for some of the most vital technologies in the world. Our advanced bonded strain gage transducer technology, hybrid microcircuit design and advanced manufacturing techniques have made Paine Electronics' pressure transducers the preferred choice for customers with applications that require long-term stability in challenging environments.
High Pressure Transducers: Paine's high temperate pressure transducers are well respected in the industry for accuracy and reliability. Our proprietary technology of wound strain wire bonded to a sensing tube is accomplished under rigorous precision at 10x to 50x magnification. This level of precision yields a high temperature pressure transducer suitable for the highest demands of any application.
Our new miniature pressure transducer is only .5 inches in diameter. Because of its small size, this transducer can easily be adapted to many existing down-hole measurement tools. What's more, the unit can be modified to fit your most exacting requirements.
Engineering: The Engineering Department provides customers with cost-effective and reliable solutions for specialized transducer applications. As your partner in developing a successful design solution, Paine Electronics library of custom designs provides a quick and reliable basis. Frequently, existing pressure transducer designs can be simply modified on our sophisticated CAD system, saving you significant development costs. Our engineers can also develop new designs if needed to meet your particular parameters, including:
- High and Low Temperature
- Intense Vibration
- Shock and Acceleration
- Highly Corrosive Media
- Acoustic Noise
- Electromagnetic Pulse
- Electrostatic Discharge
- Humidity
Custom Design: Over 80% of the Paine Electronics business is in developing custom designed transducers. Our on-site machine shop, hybrid microcircuit facility and Specialty Production Department are dedicated resources for providing cost-effective custom transducers - even in small quantities.
Design challenges frequently faced by Paine Electronics’ custom transducer engineers include dual- or quad-channel redundant, unusually small or large transducers, ability to withstand corrosive media, or intrinsically safe transducers.
 Expert Machining: Paine Electronics' fully-staffed machine shop includes technologically advanced manufacturing equipment, allowing us to customize transducers to unique physical requirements. This expanding technology has allowed us to provide specialized transducers such as miniature transducers for oil well down-hole logging equipment and the utilization of specialized metals for casings and components to withstand even the most extreme conditions.
Our CNC lathes are capable of machining strain-gage diaphragms to tolerances within .0001 inch. Other specialized machining and tooling processes are capable of handling special materials, such as titanium and Inconel®. Enhanced welding processes include semiautomatic tungsten inert gas (TIG) welding, which creates a clean and even weld using the machined flanges on a transducer casing itself as the weld filler metal.
Our highly skilled machinists are capable of building, programming and tooling prototype parts quickly to unique specifications, including extreme tolerances, special alloy requirements or precision machined parts.
 Hybrid Manufacturing: With the internal capability to produce thick film hybrid microcircuits, more than 65% of Paine's transducers are designed with built-in electronic signal conditioning. Our experience in creating uniquely shaped circuits for pressure transducers has established our reputation in producing hybrids in unusual configurations. Innovative designs continue to reduce physical size and increase reliability through resistance to shock and vibration.
Virtually every hybrid manufacturing process is completed in-house - from printing and firing our own ceramic substrates to populating boards with advanced hybrid circuit technology. This provides increased design flexibility and service, and ensures that Paine’s pressure instrumentation will consistently outperform in challenging applications and environments. Our in-house capability also enables us to respond to your needs quickly, even if you need a small number of sensors or need us to manufacture your own design.
Unsurpassed Quality: Paine transducers are engineered to withstand extreme environments, and accordingly are built with special alloys to ensure longevity and reliability.
Inconel 718 alloy has consistently proven to provide excellent stability and is accordingly our preferred metal where long term stability is important. For example, we have used it extensively in our Miniature Down-hole Pressure Transducer, where H²S and other harsh fluids exist in down-hole well-logging environments. Inconel is also used for metal-to-metal seals, eliminating the standard o-ring that can extrude or cause leakage under high pressure.
Titanium is used in our oceanographic transducers due to its compatibility with sea water. The titanium sensing elements enable each sub-sea pressure transmitter to provide extremely accurate measurements with virtually no hysteresis.
For applications where adverse weather, intense vibration or electromagnetic interference might occur, hermetically sealed stainless steel casings protect the precise internal instrumentation.
  Precise Testing: Paine transducers must operate under some of the most formidable conditions. To meet these, Paine Electronics has developed much of its own unique test equipment and procedures that every transducer undergoes:
- Each transducer is routinely tested up to 150% of its rated pressure, and heat cycled to 25°F above its maximum operating temperature.
- Each unit undergoes three complete test cycles during its manufacturing and logs a thorough test profile of its performance.
- All units with signal conditioning undergo a 24-hour burn-in period.
 In addition to Paine Electronics own testing procedures, we regularly provide additional ATP's to meet specialized customer requirements. For example, transducers for aerospace applications may undergo thermal cycling and burn-in between -65°F up to 500°F, G-force acceleration, or extreme vibration testing. Transducers for oil well logging systems are cycled repeatedly through a wide range of temperatures and pressures simulating the down-hole environment.
All testing equipment is routinely tested and stringently calibrated in our Calibration Laboratory.
