New Endevco Valuline Accelerometer Family.
Noise and vibration specialist, Brüel & Kjaer has launched
Endevco's new Valuline accelerometer family with the
variable capacitance (VC) model 7596.
Economical and rugged, the new model 7596 offers a low cost solution
for low-level, low frequency applications. The Valuline has many of the
same features as Endevco's rugged model 7290A Microtron accelerometer
making the new 7596 ideal for applications where the 7290A's tight
thermal characteristics are not required. Applications include laboratory
measurements, ground transportation studies and measurements where
the accelerometer will be subjected to high shock levels up to 10,000 g's.
The model 7596 is also suitable for modal studies on large structures.
Four models are available offering ±2, ±10, ±30 and ±100g measurement
ranges. Specifications include sensitivity of 1000 ±20mV/g, 200 ±10mV/g,
66 ±4mV/g and 20 ±1mV/g respectively, frequency response from 0 to
15Hz, 0 to 500Hz, 0 to 800Hz and 0 to 2000Hz respectively and mounted
resonance frequency of 1300, 3000, 5500 and 5500Hz respectively.
Operating temperature range is -55 to +121°C for all models.
Gas damping and internal over range stops enable the anisotropically
etched silicon microsensors to withstand very high shocks and acceleration
loads. The use of gas damping in the sensor results in very small induced
changes of frequency response while the patented sensor design
ensures immediate stability making the unit ready to take accurate
DC (steady state) or dynamic data within 1ms.
The Endevco model 7596 operates from 9.5 to l8V DC (or ±4.75 to
±9V DC) and provides a high level, low impedance output that is high
enough to drive most laboratory instruments, tape recorders and data
acquisition systems without amplification or signal conditioning.
The output can be fed into either a differential or single-ended amplifier
or standard bridge electronics with 10V DC excitation if required.
