Triaxial accelerometer TriACCxI20

MEMSG-forcevoltage output

Overview The TriACCxI20 is a compact triaxial accelerometer designed for demanding industrial and railway environments. It provides precise acceleration measurement on all three axes and offers industrial signal outputs for straightforward integration into monitoring and automation systems.

Key facts

• Triaxial MEMS accelerometer in robust stainless steel housing
• Measuring range ±20 g
• Dimensions: 20 × 27 × 27 mm
• Operating temperature: -40 … +85 °C
• Type-tested according to railway standard DIN EN 50155
• Current output (4-20 mA) available; voltage output option

Description The TriACCxI20 combines a compact footprint with industrial-grade robustness. Its triaxial sensing measures simultaneous acceleration across X, Y and Z axes for complete vibration and shock analysis. The stainless steel housing and optional IP67 cable version enable use in harsh or contaminated environments. The sensor supports a defined static signal at rest, allowing direct measurement of static acceleration (e.g. gravity). Supply voltage range 9 to 30 V DC ensures compatibility with common industrial power systems.

Applications

• Railway: condition monitoring of axles and car bodies, vibration and impact detection; type-tested to DIN EN 50155
• Industrial machinery: machine and plant vibration monitoring, condition-based maintenance using standardized outputs (e.g. 4-20 mA)
• Harsh environments: IP67 cable option for use with moisture, dust or washdown processes
