Accelerometer operates at 180C
A
Bruel and Kjaer product story
Edited by the Engineeringtalk editorial team
Jan 21, 2009
Bruel and Kjaer have designed an accelerometer capable of continuous operation up to 180C.
The Thetashear1 accelerometer Type 4526 design provides low susceptibility to temperature transients.
Two versions are available: the 4526 with 100mV/g sensitivity and the 4526-001 with a sensitivity of 10mV/g.
Thetashear1 consists of a central mass and two piezoelectric elements which undergo a shear deformation when the accelerometer is subjected to a mechanical vibration along its main axis.
The Deltatron2 name identifies products that operate with a constant-current power supply and give output signals in the form of voltage modulation on the power supply line.
The 4526 is ideally suited to applications such as gas turbine auxiliary equipment, environmental stress screening, and automotive engine and exhaust systems.
