Single axis charge mode accelerometer
Dytran Model 3316C2 is an electrically i solated ultra- high temperature piezoelectric charge mode accelerometer designed to operate reliably i n temperatures up to + 530° C. A unique, singlecrystal, planar shear charge mode sensing element mounted in a miniature hermetically sealed Inconel housing enables the 3316C2 to operate at extremely high temperatures over l ong periods of time, promises the manufacturer. Employing Silver Window technology, a Dytran patented feature on the top cover of the accelerometer housing allows a diffused oxygen molecule to pass through at high temperatures, replenishing oxygen to the crystal while maintaining the hermetic seal i ntegrity. This i nnovative feature assures continued high temperature operation with no loss of insulation resistance due to oxygen deprivation, says Dytran.
The Dytran model 3316C2 weighs 13 grams and has a height of just 12.5mm, making it ideal for use in tight locations that are inaccessible to larger accelerometers. The calibrated sensitivity is between 1 and 2 pC/g and the upper frequency response is 5kHz (+/- 10%). Model 3316C2 has a 10-32 tapped hole and 10-32 radial connector.
This workhorse accelerometer is characterised by its small size and by an internal electrical isolation design that eliminates the need for an additional isolated mounting block. Model 3316C2 is a great choice for high temperature applications including turbine engine test cell, exhaust manifold testing, nuclear reactor cooling tubes, automotive vibration studies, exhaust system analysis, exhaust vibration analysis and environmental stress screening (ESS).
