Uniaxial accelerometer ASC QBA-1515

MEMScrystalcurrent output

Overview The uniaxial accelerometers ASC QBA-1515 are based on proven, high-performance servo-balanced quartz sensing elements (Q‑MEMS) with a standard measurement range of ±30 g. They deliver high accuracy and long-term stability suited for structural health monitoring and precision vibration measurement in industrial applications.

Output & Electronics Single-ended analog current output 4-20 mA. Flexible power supply: 9 to 36 VDC. Resolution < 1 µg. Long-term stability: scale factor K1: 1200 ppm; bias K0: 1200 µg (1.2 mg).

Housing Robust stainless-steel housing (V2A material no. 1.4301) with protection class IP67. Circular metric M12 connector for a detachable cable. Available for vertical mounting with sensitive directions VX, VY or VZ. Customized connecting cables available on request.
