Norsonic Accelerometers
Nor1270
A general purpose accelerometer for industry and laboratory use.
Nor1288 Triaxial accelerometer
The triaxial accelerometer Nor1288 is designed for general vibration measurements and as a reference accelerometer when conducting whole body measurements using the 6 channel vibration meter Nor136. The Nor1288 is then mounted on the vehicle itself and the corrolation between the vehicle vibrations and the drivers seat can be measured.
Nor1291 Handle adaptor plate for triaxial accelerometer Nor1287
Nor1291 handle adaptor plate for triaxial accelerometer Nor1287.
The small dimension and low weight makes the Nor1291 easy to mount it on the handle bar on various devices for testing Hand Arm vibrations in accordance to various standards, such as ISO 5349. Mounting screw for accelerometer is 3mm.
The adaptor plate is strapped to the handle bar by using a standard cable tie. Maximum dimension of the cable tie is 5,9 x 2,9mm (WxH). This allows use of both plastic and steel cable ties.
Nor4557 Mounting magnet
Nor4557 mounting magnet with M4 screw for Nor1288 accelerometer. Base diameter 30 mm.
The Rare-earth magnet material ensures a high magnet mounting force.
Nor1292 Triaxial geophone
The Nor1292 triaxial geophone is a sensitive transducer for vibration velocity based on a rugged geophone construction used by seismologists and geophysicists for decades. One main application is for the measurement of vibrations in buildings. The frequency response is essentially flat from the resonance frequency 4,5 Hz and up to at least 500 Hz. However, by using the frequency compensation found in some Norsonic instruments like the vibration meters Nor133 and Nor136, the applicable frequency range may be extended downwards to 1 Hz. This also applies if the signal is measured as function of frequency, e.g. 1/3-octave bands where frequency correction may be used.
The transducer is a passive device and needs no power for operation.
The geophone Nor1292 plugs directly into the input socket of the six channel vibration meter Nor136. It will then connect directly to channel 1, 2 and 3. A second geophone may be connected to channel 4, 5 and 6 of the same Nor136 instrument by the use of an adapter. By the use of adapters, the unit may be connected to the triaxial vibration analyzer Nor133.
The unit may also be applied in connection with a suitable sound level meter like sound analyser Nor140. Only one direction can then be measured at the time by a one-channel instrument.
