Miniature MEMS High Amplitude Shock Accelerometers for Aerospace, Defense, Extreme Test and Measurement Applications

 

April 11, 2008, Depew, NY, USA – The Aerospace & Defense division of PCB Piezotronics (PCB®) has announced the launch of Series 3991 & 3993, a family of MEMS-based, miniature high amplitude 20,000 g shock accelerometers, which are among the industry’s smallest. Series 3991 & 3993 MEMS-based miniature high amplitude shock accelerometers, available in both single axis and triaxial configurations, represent the state-of-the-art for miniature, high-amplitude, DC response acceleration sensors, capable of measuring long duration transient motion, as well as responding to and surviving extremely fast rise times, typical of a high-g shock event. Several configurations are offered to fulfill a variety of installation requirements, with a standard footprint that is a drop-in replacement for competitive models. Each style shares the same air-damped acceleration sensing element, which is micromachined from silicon using the latest advances in etching techniques. This tiny element measures just 2.5 x 1.7 x 0.9 mm (l x w x h) incorporating a seismic mass, protective over range stops, and a full-active, piezoresistive Wheatstone bridge, which provides minimal zero shift, very low power consumption and DC response capability ...

New Generation Pressure Measurement

 

Presens AS has introduced the PRECISE, a rock solid pressure and temperature transmitter designed for calibrators, digital gauges and other applications where high accuracy, low drift and high resolution is required. In comparison to conventional silicon pressure sensors that use diaphragms with a piezoresistive resistor bridge to measure stress, Presens pressure sensors measure pressure-induced compressive stress with a piezoresistive Wheatstone bridge integrated on a tubular silicon structure. The mechanical design of the sensing element makes it possible to develop extremely robust and sensitive sensor solutions. With a guaranteed total error band (all possible errors) of < ± 0.01% FS, high pressure turndown ratio and an inherent tolerance to over-pressure and pressure spikes, the PRECISE sensor offers a level of performance unparallel to none ...

New Digital BMA020 Acceleration Sensor

 

Bosch Sensortec has launched the BMA020, expanding its selection of ultraflat, digital triaxial acceleration sensors. In this way, the Bosch subsidiary enables a broader penetration of MEMS sensors into consumer electronics market. Many manufacturers in these markets are discovering what are in part spectacular new functions paired with user advantages made possible by MEMS sensors. But mass markets for consumer electronics have their own laws, presenting component manufacturers with quite different challenges to traditional MEMS markets. Bosch Sensortec has consequently initiated product diversification in order to offer big industry customers sensors of high quality and with performance matched to the particular purpose. The dominance, witnessed to date, of universal sensors capable of taking on so many different applications is receding, to make way for components like the BMA020 that are designed to meet specific market requirements ...

Thermal Flow Sensor for the Use in Explosive Environment

 

SCHMIDT Technology expands the range of products by offering a new thermal flow sensor for the use in explosive environment. Designed for the operation according the ATEX-directives, the sensor falls in the category 3G and can be applied in ATEX-zone 2. The insertion sensor with a 9 mm stainless steel tube can measure the flow velocity and detect the direction of clean air and gas flow. The microcontroller based electronic unit is integrated in the tube. The precise sensors tip contains a super fast sensor element in an aerodynamically designed and mechanical protected chamber.The analogue output for the measuring result provides a voltage or current signal. Two switching outputs indicate the flow direction and a limit value. A serial interface allows on-site programming of the sensor via PC and the adaptation of, response time, threshold and switching polarity to the operation requirements. Applications: paint-spray lines, gas flow measuring, exhaust monitoring, flow measuring in medical equipments and test plants ...

Dynamic Pressure Sensors Detect Combustion Instability & High Intensity Acoustics in Rocket Motor Testing

  

April 9, 2008, Depew, NY, USA The Aerospace & Defense division of PCB Piezotronics (PCB®) has introduced a series of dynamic ICP® pressure sensors, Series 106, 116, 122, 123 and 124, designed expressly for measurement of combustion instability and high intensity acoustics in rocket motors. The rugged, hermetically sealed, piezoelectric pressure sensors are structured with acceleration-compensated quartz sensing elements and detect rapid pressure transients, pulsations, turbulence, noise, and spikes. They are ideal for rocket motor testing to verify the amplitude and mode of instabilities during motor firings. Other applications include evaluation of liquid rocket injectors, hydraulic and pneumatic systems, exhaust systems, compressors, turbines, pumps and pipelines, jet engines, and weapons discharge ...

High Radial Load Bearing Torque Sensor

 

These unique rotating torque sensors feature a bearing system that allows the structure to be exposed to very high radial loads without damage. Most standard torque sensors require their housings to float to minimize any extraneous loading other than the torque applied to the shaft. This sensor allows for extraneous loads up to 9000lbs/40kN and overturning moments up 18,000in-lbs/2030Nm to be reacted through the housing.  Its use allows the operator to eliminate pillow block bearings and reduce overall torsional inertia, thereby increasing the overall stiffness of the driveline.  Ideal for measuring components that are subjected to these loads such as steering columns, pulleys, and universal joints ...

Explosion & Blast Pressure Sensors Offer Low Noise and High Output Measurements

 

Depew, NY, USA – Series 137A Quartz, free-field, ICP® blast pressure pencil probes from the Aerospace & Defense division of PCB Piezotronics (PCB®) are designed for a broad range of explosion, blast, and shock wave testing.  Applications include measuring blast pressure in free-field or closed bunker arenas to obtain peak pressure, total impulse, shock wave and time-of-arrival measurements often used to study blast effects on structures, vehicles, and humans.

 

Quartz, free-field, ICP® blast pressure pencil probes have an extremely fast 1 micro-second response time, with resonant frequencies to 500k Hz. ICP® technology features integral microelectronics that provides a high signal-to-noise ratio compared to silicon semiconductor sensing technologies, which require external amplification. The high-level 5 volt output signal is capable of driving cable runs hundreds of feet in length, to a safe zone for data acquisition. Sensors are frequency tailored to capture both peak pressure and total impulse calculations ...
