Accelerometer TP-ACC20 - 09 | DCT | Test and Measurement

Features

Measures acceleration on two axes with a range of ±2 g, suitable for both static and dynamic measurements
Voltage output design with typical sensitivity of 420 mV/g for accurate signal analysis
Low power consumption, drawing less than 0.5 mA from the instrument’s extension connector
Compact and lightweight sensor unit with integrated magnets and velcro for flexible and secure mounting on various surfaces
Includes a manual external trigger button with BNC connectors, allowing for manual control of measurement initiation
Compatible with high-performance instruments like the Handyscope HS5, HS6, HS6 DIFF and WiFiScope WS5, WS6, WS6 DIFF
Long, durable cabling: 2.5 m for the sensor and 2 m for the trigger button, enabling easy access and maneuverability in testing setups
Wide bandwidth up to 500 Hz, ideal for capturing fast motion or vibrations
High sensor resonant frequency around 5.5 kHz ensures minimal interference from mechanical resonance

The Accelerometer TP-ACC20 is a dual axis accelerometer combined with a manual, external trigger button, designed to be used with the Handyscope HS3, Handyscope HS4, Handyscope HS4 DIFF, WiFiScope WS4 DIFF (order code TP-ACC20-25) and Handyscope HS5, Handyscope HS6, Handyscope HS6 DIFF, WiFiScope WS5, WiFiScope WS6, WiFiScope WS6 DIFF (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.

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.
