Laser Measurement

Ophir Photonics’ 1000WP-BB-34 high-power water cooled thermal sensor is designed with the requirement that all materials coming in contact with the cooling water are either copper or nonmetallic. This eliminates the possibility of contaminating the water or corroding the sensor, improving the accuracy and reliability of the measurements. The sensor features a 34-mm aperture and a wide dynamic range, measuring powers from 5 W to 1000 W and energy from 400 mJ to 300 J. More detail at http://articles.sae.org/13730.

Unmanned Ocean Drone

Accurately forecasting weather conditions and currents prior to mission deployment is an invaluable intelligence tool for the warfighter. Being able to accurately predict a Category-5 typhoon or hurricane, instead of a tropical storm, also saves lives, saves property, and saves time in evacuations. The Liquid Robotics' Wave Glider®, a surfboard-sized ocean drone filled with sensors, computers, and communications equipment, can survive a Category-5 typhoon while continuously collecting and transmitting meteorological and oceanographic data. Previously this type of data was unobtainable because it was too risky to send manned ships out in the middle of a hurricane/typhoon; buoys can become severely damaged or come off their moorings in such conditions; and satellites have difficulty seeing through the dense cloud cover.

Rotary Transformer Coupled Torque Sensors

The Model T261 series rotary transformer coupled torque sensors from SensorData Technologies meet the demanding inline testing requirements of small motors, pumps, compressors, turbines, fans, and other fractional horsepower rated devices. Overall performance of the T261 Series offers higher stiffness and lower inertia than comparable torque sensors on the market. Units are available in three standard rated capacities of 5, 10, and 20 K rpm, along with three unique mounting configuration options (others upon request).

Oil Pipeline Fault Detection System Determines Material Permittivity at Microwave Frequencies

Researching fault location techniques for the oil industry requires data on the complex permittivity of the polyamide Rilsan at microwave frequencies. Rilsan is a vital material used in oil pipe construction. Currently there is no published data for the complex permittivity of Rilsan. The task for this project was to develop an accurate method to measure the complex permittivity of Rilsan to gain an understanding of the dielectric relaxations that occur within it. A fast, accurate method was developed using a vector network analyzer (VNA) and rectangular waveguide.

Submersible Pressure Sensors

The AST4520 media-isolated, submersible pressure sensor from American Sensor Technologies (Mt. Olive, NJ) features a flush diaphragm steel cage design with stainless steel construction for level monitoring of turbulent tanks with viscous media. It is approved to UL/cUL913 Class 1, Division 1 IS, Groups C and D with an approved barrier. The steel cage design allows for proper flow of media while keeping the sensor at the bottom of the tank or well. It also features an engraved 316L housing and Kynar PVDF cable.

Units operate at temperature ranges of -40 to 185°F and offer pressure ranges from 0-5 to 0-15 PSIG. All units come standard with EMI/RFI protection of 100V/meter and a 4-20mA output.
