We're among a handful of companies offering transducers that can measure pressures up to 200,000 psi with superior accuracy and reliability. Foil-based strain-gauge technology enables our sensors to withstand pressures that would destroy silicon-based or micromachined-type sensors.

The Model TJE strain-gauge transducer measures pressure up to 60,000 psi with +/- 0.1% accuracy. For ranges up to 100,000 psi, we offer the Model HP with 0.5% accuracy and operating temperature range from –65 to 250 degrees Fahrenheit.

For your most demanding applications, we use a hoop-stress design and special metal alloys to custom-build transducers that measure up to 200,000 psi safely, reliably, and with 0.75% accuracy. Typical applications for these tough, reliable high-end instruments are in oil-field geology and aerospace research and development.

Our high-pressure sensors offer optional compensated temperature ranges from –65 to 250 degrees Fahrenheit with either millivolt or high-level outputs. Versions certified for hazardous environments are also available. All sensors ship with certificates of calibration and traceability.

For high-frequency pressure measurements or in applications with severe space limitations, Honeywell Sensotec offers subminiature flush diaphragm pressure sensors in ranges from 0–100 psi to 0–20,000 psi (0–10 to 0–1,400 bar). All-welded, machined stainless steel sensing diaphragms ensure ruggedness. Bonded piezoresistive and metal foil strain gauges offer high reliability. Millivolt and optional high-level outputs are compatible with most data acquisition systems.

Applications include aerospace hydraulics, flow meters, oilfield down-hole drilling and well logging tools, and automated metering and dispensing control for high-viscosity materials (such as automotive sealants, gaskets, and automated paint systems). Submersible designs with oceanographic-type cabling are also available.

The Super TJE model with 0.05% F.S. accuracy is offered in ranges from 0–10 psi through 0–7,500 psi. Separation of the strain-gauged element from the welded diaphragm by a unique double outer skin design reduces the affect of thermal shock and assures long-term stability. Extra temperature compensation reduces thermal errors from temperature changes to less than +/- 0.0015% F.S./°F.

A century after Ohio brothers Orville and Wilbur Wright first flew their Wright Flyer at Kitty Hawk, North Carolina, Ohioans again played a major role in the history of flight when Honeywell Sensotec provided instrumentation that helped test the reproduction plane built by The Wright Experience of Warrenton, Virginia, for the Experimental Aircraft Association. Corporations and government agencies, including NASA and the FAA, backed the project.

Other teams have simply constructed a plane similar to the Wright Flyer. But the Wright Experience team reverse-engineered the Flyer by examining the original plane (now in the Smithsonian Institution) and using notes left behind by the Wright Brothers, computer simulations, and air-tunnel testing. The result: the world's most accurate reproduction of the original plane.

Honeywell Sensotec provided an essential piece of the highly reliable test and measurement instrumentation that helped the team succeed. The firm's wireless telemetry system enabled the flight engineers to measure the torque between the plane's engine and the propellers. The Wrights' propeller design enabled them to get the maximum possible torque from their small engine and was one of the key factors that made their plane fly in 1903. Modern engineers have found the Wrights' propeller design to be only 2.5% to 3% less efficient than today's computer-designed wood propellers.

The Honeywell Sensotec wireless telemetry system is an off-the-shelf model usually used to measure rotor shaft torque in helicopter testing. No special modifications were needed for the Wright Flyer project. Aerospace research firm ViGYAN, which provided the project's onboard flight data recorder, specified Honeywell Sensotec's product because of its compact size, high frequency response, noise rejection, and the company's knowledgeable and accommodating engineering staff.

From the Honeywell Sensotec strain gauges and a radio transmitter mounted on the Wright Flyer's propeller shaft, data were sent to a radio receiver mounted either on a test stand or one of the wing struts. The receiver then channeled the data to a ViGYAN data acquisition system that also collected data from other instruments. The flight team found that Honeywell Sensotec's telemetry system gave them more information than they expected: They were able not only to check propeller movement but also to tune the engine by using the system's torque measurements. The team also praised the system's signal strength, vibration resistance, and ease of monitoring.

Honeywell Sensotec engineer Andy Bell, a long-time aviation buff, traveled to Warrenton, where the plane was built, to work with the flight engineers. Bell consulted on the design for the bracketry that held the Sensotec equipment on the plane during its wind-tunnel tests and first two test flights. Although weather prevented the reproduction model from becoming airborne on the December 17, 2003, Centennial Celebration attended by President Bush, the little 605-pound plane did actually fly on the earlier test flights. Bell described Honeywell Sensotec's participation in the history-making project as "an exciting way to celebrate 100 years of flight."

This series provides more than 20,000 sensor configurations in accuracies of 0.1% or 0.25 % F.S. and pressure ranges from vacuum to 0–10,000 psi with outputs of 0–5 VDC, 0–10 VDC, or 4–20 mA (2-wire). We offer six pressure ports and six electrical terminations, including a DIN-style (43650) electrical connector, and an integral cable with ½ in. conduit connection. Typical operating temperature ranges are –10°F to 200°F and 40°F to 240°F (compensated). These fully-welded stainless steel and Hastaloy® units offer overpressure capability to 4x rated range. Amplified units offer optional side-mounted zero and span adjustments, buffered shunt calibration, and CE marking.

Because we know that long-term stability is key to maintaining the highly accurate performance of our sensors over the long term, we've focused on minimizing output drift and zero shift. And we've succeeded: Many of our barometric pressure sensors have been under test for over 8 years and have never moved more than 0.05% F.S. from the day that they were built. Quality-conscious engineering design, manufacturing, and testing ensure that our sensors are among the most stable produced anywhere in the world. More>>
