HBM Introduces Digital Charge Amplifier for Piezo Sensors

By DE Editors

The CMD600 charge amplifier is designed for use under harsh ambient conditions.

The new CMD600 digital charge amplifier from HBM acquires signals from a connected sensor and makes them available to a downstream machine control as an analog voltage signal (0 to ±10 V) up to a measuring bandwidth of 30 kHz, or in digital form as measured value streaming, via Ethernet.

HBM says the CMD600 is compact, robust, and noise-immune, making it suitable for industrial applications. Piezoelectric sensors can be operated with the charge amplifier. Sensitivity and measuring range can be adjusted using the CMD Assistant software in a range of 1:10,000.

The included CMD Assistant software allows the user to configure the amplifier via the integrated Ethernet interface. The stripchart service tool integrated in the software makes it easy to display and record the measured values. The amplifier supports the Transducer Electronic Data Sheet (TEDS), so downstream amplifiers can detect and automatically use the measurement chain settings.

The charge amplifier has two digital outputs for applications in machine control, and these can be used, for example, for rapid limit value control or peak value monitoring up to 10 kHz. Typical areas of application for the CMD600 are found in production, joining and forming processes, in test benches for engines or gears, and in research and development.
