Application of Wireless Sensor Network in Indoor Alarm


Abstract: The digital electronics, embedded systems and wireless communications together result in wireless sensor networks. A general wireless sensor network consists of a number of sensors spread across a geographical area. Each sensor has wireless communication capability and sufficient intelligence for signal processing and networking of the data. So these networks have a wide range of potential applications, including security and surety and surveillance, control, actuation and maintenance of complex systems, and fine grain monitoring of indoor and outdoor environments. In the paper, a small scale of wireless sensor network is presented and applied to indoor alarm in detail.

High Temperature, Through The Case, Eddy Current Blade Tip Sensors

Abstract: Hood Technology has developed eddy current sensors that can operate up to 1000°F and can see “through the case” of an engine and make measurements of blade tip timing, tip clearance and interblade angle. These measurements are used in conjunction with a Non-Intrusive Stress Measurement System (The Hood Kit NSMS) to detect synchronous resonances, the onset of rotating stall, asynchronous vibration like blade flutter, foreign-object-damage, High Cycle Fatigue of blades and Low Cycle Fatigue of disks (crack detection). The technology has been demonstrated in the laboratory, in spin pit testing, and on live engine tests up to 1000°F. Preliminary experiments have shown that it also has the potential for extension to cryogenic temperatures for use in turbo-pumps for rocket motors, and to turbine temperatures (approximately 2000°F).

High Amplitude Triaxial ICP® Accelerometers


Depew, NY - The Vibration Division of PCB Piezotronics, Inc. has introduced Model 350B50 high amplitude triaxial ICP® accelerometer that combines three, 10,000 g sensing elements in one housing. The 350B50 features a built-in, 2nd order, low pass filter between the sensor element and the amplifier, which reduces the risk of saturation at high frequencies.


Sensor contains built-in signal conditioning circuitry that can be powered by a 2-20 mA constant current, regulated DC voltage of 18-20 VDS. The sensor is ideally suited for high amplitude random vibration testing, qualification of aerospace components and shock measurements.

ABR1000 Air Bearing Rotary Stage Redefines Accuracy

and Performance Benchmarks


Aerotech's ABR1000 ultra-high precision rotary stages combine air bearing technology and direct drive, slotless/brushless servomotors to provide unsurpassed error motion, wobble performance and velocity stability for high-throughput production and test applications such as MEMS (Micro-Electro-Mechanical Systems). MEMS is a specific area of Nanotechnology concerning the integration of sub-micron mechanical elements, sensors, actuators, and electronics on a common silicon substrate through various micro-fabrication techniques. This rapidly evolving technology demands enhanced-precision automated mechanical systems capable of providing highly stable, accurate and repeatable positioning platforms. The ABR1000 is also well suited to other demanding manufacturing and test applications such as wafer inspection/singulation, DVD mastering, disk drive test/servo writing, optical inspection and fabrication.

New EE80: CO2, RH and Temperature Transmitter for Building Control


The Carbon dioxide (CO2) content in the air is an important parameter for assessing the quality of the air. Everyone knows the effects of high CO2 concentration during “never-ending” meetings, even if the topics are very interesting: tiredness, sleepiness and headaches. With every breath we take we convert Oxygen (O2) into CO2 and by this increase the CO2 content in the surrounding air. As guideline, the highest CO2 content of „well ventilated“ air is typically below  800ppm CO2, while the fresh outdoor air contains around 360ppm (it is typically 400 to 450 in urban areas). Since a high CO2 content in the air has a negative impact on comfort and performance, CO2 measurement is becoming as common as temperature and humidity in buildings. Based on CO2  measurement one control outside air ventilation to avoid under ventilation or excessive over ventilation that can waste energy.


The new transmitter series EE80 from E+E Elektronik is an ideal choice for building control applications. The EE80 measures the three most important physical quantities for air quality control and comfort: CO2, relative humidity and temperature.  This is the first transmitter available that accurately measures all three parameters. The CO2 measurement principle in EE80 is based on the proven principal of infrared gas detection. The measuring range is 0...2000ppm. A patented self-calibration feature compensates for aging of the infrared source and assures a unique long-term stability for the CO2 sensor. Relative humidity in the range of 10...90% RH is measured with the proven capacitive E+E humidity sensor. A built in, state-of-the-art microprocessor ensures high accuracy and excellent long term stability.


The EE80 Series transmitters include combination sensing for CO2, relative humidity and temperature.  There is also a CO2 and temperature version. The EE80 humidity sensor  utilizes  plug-in module.  As a result, humidity measurement capability can easily be added to any existing CO2 and temperature EE80.

Affordable Sensor Measures Heat Distribution


East Hanover, NJ (USA) - Sensor Products Inc. presents Thermex®, a temperature indicating sensor paper (TISP). Since they reveal temperature distribution between any two heated contacting surfaces, TISP’s are a valuable aid in R & D as well as in QC/QA procedures for assessing heat distribution.  Applications benefiting from this innovative yet affordable technology include heat sealing bars, welding heads, clutch and brake assemblies, and many other industrial uses.


Senior technical manager Jeffrey G. Stark says, “Thermex® temperature sensor comes in the form of a large thin sheet, actually a paper. When placed between heated surfaces, the sensor instantly and permanently turns varying intensities upon contact.  Color variations between light blue to black reveal minute variations in temperature. Response time is 0.1 seconds or less, with heat detection ranges from 93° C to 149° C.”


As a non-destructive testing concept, Thermex® makes temperature distribution measurement simple and affordable. Its ultra-thin profile makes the sensor ideal for environments unable to accept traditional heat or temperature indicators. Available in 17” by 14” sheets, TISP’s can be trimmed with scissors to accommodate smaller applications.

Explosion-Proof Laser Transmitter Measures Level, Distance

and Position in Challenging Environments


Prairieville, LA (June 1, 2004) - K-TEK, a leading manufacturer of state-of-the-art level instrumentation for liquid and bulk solids detection, today announced the SureShot™XP laser transmitter designed for measurement of dry bulk solids, opaque liquids, and slurries in challenging environments. The laser features virtually no beam divergence and is housed in an explosion-proof assembly with screw-on, glass cover for quick and easy access. A dual-compartment design allows users to isolate the wiring and terminations from the sensing elements and internal electronics. With virtually no beam divergence, and therefore no false echoes, the SureShot XP is ideal for use in vessels with complex internal structures and numerous obstructions, such as in petrochemical refineries and chemical plants, or in small, tight spaces, such as stilling wells. Designed to meet the requirements for use in hazardous areas (Class I, Division 1 and 2, Groups B,C,D), the rugged, powder coated aluminum enclosure is rated for IP67 or NEMA 4X, DIP ratings. This ensures operation even in the harshest of conditions.
