Advanced impedance head available from DJB Instruments UK

0

DJB Instruments UK has launched the AF/50/5 and AF/100/10 IEPE impedance heads, which integrate 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 30g and an operating temperature range of -40°C to +121°C (-40°F to +249°F). IEPE sensitivity options are available, including 5mV/N and 10mV/N for measuring force and 50mV/g and 100mV/g for acceleration dependent.

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.
