Accelerometer TP-ACC20

Accelerometer TP-ACC20


The Accelerometer TP-ACC20 is a dual axis accelerometer combined with a manual, external trigger button, designed to be used with the Automotive Test Scope ATS5004D, Automotive Test Scope ATS5004DW (order code TP-ACC20-25) and Automotive Test Scope ATS605004D-XMS, Automotive Test Scope ATS610004D-XMSG, Automotive Test Scope ATS605004DW-XMS, Automotive Test Scope ATS610004DW-XMSG (order code TP-ACC20-09).

The dual accelerometer is a low power dual axis accelerometer with voltage outputs. It can measure accelerations in two axes, up to ± 2 g. It can measure both dynamic acceleration and static acceleration (gravity).

The manual external trigger button can be used to trigger measurements in situations where no trigger condition can be derived from the input signals.

Accelerometer TP-ACC20 sensor front

The acceleration sensor of the Accelerometer TP-ACC20 is placed in a small package with a long, thin flexible cable. The package contains strong magnets to attach the sensor to magnetic (steel) surfaces without the need of screws or clamps. One side of the package contains a patch of velcro, to attach the sensor to fabric surfaces.

The Accelerometer TP-ACC20 also contains a manual, external trigger button. This button can be used to manually trigger measurements in situations where no trigger condition can be derived from the input signals. The manual external trigger button has a solid aluminum body and is fitted with a female BNC connector. A long flexible cable with a male BNC connector is used to connect the button to the instrument.
