Testing triaxial transducers

 

 

An optional triaxial accelerometer angled adaptor can be purchased separately (part number 
TAA01). The fixture has a mounting surface that has been designed to 

excite all of the sensor’s 

axes simultaneously.  The resulting vibration level will be approximately 57.8% of the applied 
acceleration. It is important that the sensor be mounted using its positioning pin to achieve the 
desired result.

Note that there are two holes on the mounting surface.  The 10-32 threaded hole is for mounting the 
sensor, the unthreaded hole is to accommodate the alignment pin provided on the 993B-7-M12 
accelerometer.  The weight of the fixture is 93 grams.

Universal AC adaptor

 

 

If AC operation of the ReferenceMate2500 is required, part number REF003 is available. This AC 
adaptor comes with several universal plug adaptors and will operate from 50/60 Hz 110/220 VAC.  
 
To power the shaker with the AC adaptor, unscrew and remove the DC jack cover on the rear of the 
unit.  Store the jack cover in a safe location.  Connect the coaxial power plug of the power supply to 
the DC jack on the ReferenceMate.  When the power plug is inserted into the DC jack, the batteries 
are automatically disconnected.  After connecting the adaptor to the shaker, plug the adaptor into an 
AC supply. 
 

CAUTION

:  The external supply is rated for indoor use only.  The shaker should not be 

powered with an external supply when used outdoors or in wet locations.  The shaker does 
not meet the IP54 rating when the DC jack cover is not securely installed.  The DC jack cover 
should always be installed whenever an external supply is not being used.
