Acceleration 101
 
The engineering unit used to measure acceleration is "g". 1 g is equivalent to 32.1741 ft/sec2.
An accelerometer with a range of ± 10 g's will measure acceleration from -321.7405 ft/sec2 to +321.7405ft/sec2. The value of 1 g is also expressed in other units such as inches (386.0885 in/ sec2) and meters (9.8057 m/ sec2). Varying g levels are part of one's everyday life, whether accelerating in a car, taking off in an airplane, sneezing or riding a roller coaster. We often do not know how much the g level is -but we certainly feel it.

Systron Donner Tactical MEMS IMU (Inertial Measurement Unit)
 
The SDI500 from SYSTRON DONNER

Leveraging industry's leading MEMS technology to provide previously unheard of capabilities in angle random walk values (0.02°/√hr.) without loss of tactical grade levels across military environments, including 1°/hr. bias stability, the SDI500 is designed to achieve the demanding performance levels required in sophisticated systems applications. It is particularly suited for use by Integrators and OEMs, packaged in a highly miniaturized, cylindrical configuration with a volume of only 19 cubic inches. Boasting a 20-Year lifetime capability without requiring calibration and a MTBF of more than 50,000 hours, multiple output data formats and SDLC, RS232 and UART output interfaces are provided in this revolutionary IMU for optimized systems protocols.

NEW!   VDM28 Distance Measurement Sensor from P+F
 

Pepperl+Fuchs Revolutionizes the World of Distance Measurement

 

New VDM28 distance measurement sensor offers precise technology in the smallest housing

at an incredibly low price.

 

Determining distances is one of the most common metrological applications in automation technology. The market supplies many set solutions, yet not every technology is ideal for each application. The new VDM28 distance sensor is setting standards in this dynamic field. With a measuring range up to 8 m, the sensor reliably detects distances in diffuse mode. The groundbreaking Pulse Ranging Technology (PRT) measuring principle is used.

 

For the first time, a red laser emits short light pulses to determine distance by measuring the time of flight of the reflected pulses. The highly visible beam also enables optimal alignment. This is an innovative combination for sensors with PRT and ensures perfect performance and convenience, while featuring the unique advantages of this technology. In contrast to other procedures, measuring accuracy is independent of object surface. The measuring principle eliminates issues such as detecting "phantom objects" or measuring fluctuations due to ambient conditions.

 

P+F VDM28 Special Features

 

The largest selection of distance measurement sensors on the market is available in the proven VDM28 enclosure design. In addition to the distance-measuring device, thru-beam sensors and retro-reflective sensors are also available. This enclosure design incorporates more optical technologies than any other.
