The LVEP-TO5 is a high-performance piezoelectric accelerometer designed for ultra-low power consumption and easy integration into wireless accelerometers and other battery-powered applications. It is also easily integrated into rotating machinery for built-in self-test (BIST) capabilities. It has the full performance of an industrial accelerometer with the low power consumption of a MEMS accelerometer. Request a complementary demo unit for evaluation.

Key features and benefits

• Ultra-low power consumption to take more measurements using less battery, only uses 5% of the power of a traditional industrial accelerometer and lower power consumption than MEMS accelerometers
• TO-5 standard packaging to seamlessly integrate into the final design, small enough for 1- and 3-axis designs
• High performance sensing element to match the measurement capabilities required for effective machinery health monitoring

Applications for the LVEP050-TO5 accelerometer include wireless sensors, battery powered sensors, and sensors powered by energy harvesting.

It can be mounted inside motors, pumps, fans, vehicles, heavy equipment, conveyors, HVAC systems, and other production assets, to enable machinery self-diagnostics and asset monitoring via the Industrial Internet of Things (IIoT).

High performance accelerometer for machinery health monitoring

Like Wilcoxon’s industrial accelerometers, the LVEP050-TO5 was designed with the resolution (50 or 100 mV/g), frequency response (up to 12.5 kHz), and acceleration range (25 g) required for effective machinery health monitoring. Despite its small size and low voltage requirements, its performance matches that of a traditional industrial accelerometer.

Ultra-low power consumption

The LVEP-TO5 has an ultra-low power consumption of 180 µW, requiring a voltage source of 3.0 – 5.5 VDC, with a current draw of 60 µA when taking measurements (and no current draw in power down mode). The power-up and settling time is typically 350 µs.

Benefits of TO-5 packaging

The high-performance vibration sensor was packaged in a common TO-5 standard transistor canister for easy integration into sensors and production equipment.

• Good vibration coupling from the canister base into the vibration pellet is essential to effective machinery health monitoring
• Light weight preserves usable measurement bandwidth
• Hermetic sealing prevents contaminants and moisture from entering the sensor, to ensure stable measurements over a long operational lifetime
