DJB Instruments UK has announced the launch of the AF/50/5 and AF/100/10 IEPE Impedance heads which integrates an IEPE accelerometer and force sensor into one device to measure dynamic acceleration and force simultaneously. The AF impedance head is manufactured in stainless steel, has a mass of 30 grams and an operating temperature range of -40 to +121°C (-40 to +249°F).
IEPE sensitivity options including 5mV/N and 10mV/N for measuring force and 50mV/g and 100mV/g for acceleration dependent on your requirements. With a low impedance voltage mode and an effective anti-jamming facility the AF impedance head is ideal for use in modal and structural analysis.
It can be attached to an input stinger that is itself driven by a modal shaker and also attached to the test structure via the two M5 tapped mounting holes. The use of IEPE sensors provides accurate measurement of applied forces over a wide bandwidth providing extensive excitation range for Modal testing, unlike other strain gauge sensors which are used for static and quasistatic environments.
As with all IEPE sensors, setup is easy and the AF can be connected directly to a data acquisition and analysis system equipped with IEPE signal conditioning within the range of 2-10mA and 18-28VDC. Cables of any length can also be supplied to suit all test set ups and the calibration certification supplied provides National traceability.
Neill Ovenden, DJB’s Managing Director said of the launch ‘This is the next product in a full program of product launches in 2017. The AF represents a continued expansion of our traditional accelerometer range into new and wider variables including Force and soon to expand further into Pressure.’
The AF range of Impedance heads are available to order now and full details including datasheet can be found on the DJB Instruments website www.djbinstruments.com, to keep up to date with other new product launches from DJB please sign up to our newsletter online.
If you have a challenging application that would benefit from high temperature accelerometers or have a new requirement looming please get in touch, the more information we have about requirements the better we are placed to develop the right solutions.
