PCB’s Adds High Temperature Accelerometer

PCB Piezotronic’s new accelerometer, Model HTJ356B01 is suited for applications that demand ground isolation to reduce electrical noise and ground loops on test articles in higher temperature environments . This design achieves the ground isolation through the attachment of the accelerometer to a three sided titanium cup that contains an insulating glass filled epoxy. This model has high temperature ICP operation up to 356 °F, with a full temperature range of -65 to 356 °F (-54 to 180 °C).

The sensing elements provide a 5 mV/g output over a 2 to 8K Hz frequency range and are hermetically sealed in a rugged, scratch-resistant, titanium housing. With an overall cube size of just 0.28 inches (7.1 mm) and weight of 1 gram, this sensor is suitable for testing in space restricted locations. Typical applications include environmental stress screening and NVH testing in high temperature environments.
