TriACCxU8

The TriACCX is a compact, robust, and versatile triaxial accelerometer that meets the highest requirements in industrial and railway applications.

Compact size & efficient integration: Measuring just 20 × 27 × 27 mm, the sensor can be easily integrated even in confined spaces. As the smallest form factor for three analog 4-20 mA current channels, it maximizes space efficiency without compromising functionality.

.

Triaxial measurement: Measures acceleration along all three spatial axes simultaneously - ideal for comprehensive condition monitoring with minimal external electronics required.

.

Noise-immune signal transmission: The current output (4-20 mA) delivers exceptional signal integrity over longer distances, ensuring reliable data transmission even in electrically noisy industrial environments. High precision is achieved through very low noise design, enabling accurate measurements across the full frequency spectrum from 0 Hz to 1000 Hz.

.

Certified for railway applications: Compliance with DIN EN 50155 ensures reliable operation even under harsh operating conditions in the railway sector.

.

Flexible measuring ranges: A wide selection of acceleration ranges (2g to 40g) allows precise adaptation to various application scenarios - from low vibration to strong shocks.

.

Robust design: The optional IP67 cable version offers protection against dust and temporary immersion - ideal for demanding environments.

.

Wide temperature and voltage range: Operates reliably from -40°C to +85°C and with supply voltages from 9 to 30 V DC.

Static signal at rest: The sensor delivers a defined output signal even at 0 Hz, enabling the direct measurement of static acceleration values (e.g., gravity).

.

Applications:

.

Railway technology: For monitoring vibration, rotational fluctuations, and sudden impacts on vehicle axles or car bodies - enables early detection of critical conditions while complying with type testing (DIN EN 50155).

.

Industrial applications: Diverse applications in mechanical engineering, plant monitoring, or vibration measurement - especially where electrical integration via standardized 4-20 mA current output is required. The noise-immune signal ensures reliable data transmission across extended cable runs.

.

Harsh environments: Thanks to its IP67 cable design, the TriACCX can be used in environments with moisture, dirt, or cleaning.

.
