Dynamic Piezoelectric Pressure Sensors

 

Depew, NY -Quartz pressure sensors from the Pressure Division of PCB Piezotronics, Inc. are designed for dynamic measurements of compression, combustion, explosion, pulsation, cavitation, blast, shock wave, pneumatic, hydraulic, fluid, and other such pressures. ICP@ or charge output pressure sensors, structured with naturally piezoelectric, stable quartz sensing elements, are well-suited to measure rapidly-changing pressure fluctuations over a wide amplitude and frequency range. Solid-state construction, hermetically-sealed housings, and laser-welded flush diaphragms provide undistorted high frequency response and durability, even in adverse environmental conditions. PCB's Series 111/112/113 pressure sensors are available with dynamic ranges to 20kpsi (138 MPa), resonant frequencies to 500k Hz, and sensitivities to 100 mY/psi (14.5 mV/kPa). Stock models and alternate mountings are available.

Intelligent Digital Signal Conditioner

 

The Electro Standards Laboratories’ Model 4325 Intelligent Digital Signal Conditioner connects directly to a standard strain gage transducer such as a load cell or extensometer, and generates a +/-10V analog output along with a serial digital output suitable for connection to a computer. The Model 4325 can compensate for transducer non-linearities using its integrated six-point calibration capability not found in standard signal conditioners. This compact unit is ideally suited for in-situ transducer conditioning and distributed process measurements. Its multidrop RS-232 serial port and simple command set allow for connection of multiple units in a serial network configuration. Features include nonvolatile memory for parameter and calibration storage, ability to select between two transducers, multi-point and mV/V calibration, remote sense excitation, and 24-bit internal resolution with 16-bit analog output. Field programmable for software updates.

Data Acquisition Instrumentation Systems on Palm Handhelds

 

CAMPBELL, CA, August 12, 2004 - Datastick Systems, Inc., once again changes the way instrumentation is done, with today's release of the Datastick® DAS-1254 and DAS-1294 data acquisition systems: including two new hardware modules that attach to PalmTM PDAs, three new members of the Datastick ConnectionTM suite of software applications that run on Palm handhelds, and a fast, easy way to get information from a handheld instrument to the desktop PC.

 

New Datastick® Report SystemTM (DRS) software eliminates one of the most frustrating problems of portable datalogging and handheld instruments: the ability to quickly view the measurement data on the desktop pc, to integrate with standard databases and other software applications in the enterprise, and to publish the data in reports and on the Web with ease. At the push of a button, DRS uses a newly developed software conduit that translates the proprietary data format into a file that Microsoft Excel software can read, copies it to the pc, launches Microsoft Excel on the pc, and seamlessly loads the data into the DRS workbook.

 

Among the many other new features are: up to 8 analog input channels, strip-chart recorder emulation, enhanced power management, lower analog input noise, and faster sample rates.

 

The new DAS-1254 and the DAS-1294 data acquisition modules, which firmly attach to the Palm handheld, have 4 and 8 analog input channels respectively, with 12-bit resolution. Users attach their analog sensors to the Datastick hardware module, making a complete portable instrumentation system for measuring pressure, acceleration, etc.

 

Designed for most Palm series-m and Tungsten T handhelds, the new DAS units also provide a digital counter input line for tachometer or accumulating purposes; a digital-switch input line for triggering, and two digital-switch output lines to start and stop external devices. New power management features and enhanced circuitry aid battery life.

Three-Component Force Sensors

 

Depew, NY -The Force/Torque Division of PCB Piezotronics, Inc., offers ICP'" and charge output Three-Component Force Sensors capable of simultaneously measuring dynamic or quasi-static forces in three orthogonal directions (X, Y, and Z), and delivering an independent measurement signal for each direction. Three-Component Force Sensors are ideal for a variety of applications, including cutting tool force monitoring, product quality assurance monitoring, modal analysis, engine mount analysis, biomechanics, and impact testing. Sensors are structured with a quartz sensing element for long-term stability, small size, high stiffness, and a wide dynamic range of 1,000 to 10,000 Ib (4.45 to 44.45 kN) in the z-axis and 500 to 4,000 Ib (2.22 to 17.79 kN) in the x and y axes. ICP'" versions utilize built-in 'microelectronics to convert the high impedance charge to a low impedance voltage; charge output versions operate with in-line charge converters or laboratory style charge amplifiers.
