MEMSindustrialcompact

Short description
The TriACCxU40 is a triaxial accelerometer with voltage output and a ±40 g measurement range, designed for industrial and railway applications.

Key facts

• Triaxial MEMS accelerometer in a robust stainless-steel housing
• Measurement range: ±40 g
• Dimensions: 20 × 27 × 27 mm
• Operating temperature: −40 to +85 °C
• Type-tested to railway standard DIN EN 50155
• Voltage output; optional 4-20 mA current output
• Optional IP67 cable version for protection against dust and temporary immersion
• Supply voltage: 9 to 30 V DC

Description

• Compact size: At 20 × 27 × 27 mm the TriACCxU40 integrates easily in confined installations.
• Triaxial measurement: Simultaneous measurement on three axes for comprehensive condition monitoring.
• Railway-certified: Type-tested to DIN EN 50155 to ensure reliable operation under harsh railway conditions.
• Flexible ranges: Wide selection of measuring ranges to adapt from low-frequency vibration monitoring to high-impact events.
• Voltage output: Straightforward integration into existing automation and monitoring systems.
• Robust design: Stainless-steel housing and optional IP67 cable version for demanding environments.
• Wide temperature and supply range: Reliable operation from −40 °C to +85 °C and 9–30 V DC supply.

Additional features

• Static measurement capability: Defined output at 0 Hz enables direct measurement of static acceleration (e.g., gravity).
• Selectable output types (voltage or 4-20 mA) extend integration flexibility.
• Designed for applications requiring precise acceleration measurement, robustness and long-term reliability.

Applications

• Railway technology: Vibration and shock monitoring on axles, bogies and car bodies; supports early detection of critical conditions while complying with DIN EN 50155.
• Industrial monitoring: Machine and plant condition monitoring, vibration analysis, and integration into control systems requiring standard electrical outputs.
• Harsh environments: IP67 option allows use in environments with moisture, dirt or cleaning operations.
