The digital charge amplifier for piezoelectric sensors assures multiple uses in many applications in the laboratory and production. It is easy to use, absolutely reliable and offers an excellent price-to-performance ratio.
PACEline CMD - The all-rounder from the PACEline product family
The CMD charge amplifier measures very fast force, torque and pressure signals. The measurement range is freely scaleable and even signals of minimum strength are available at high resolution without quality loss via a second, internal measurement range; the CMD is thus eminently suited to measuring very small forces.
The very wide measuring range (from 50 to 600,000 pC with CMD600 and from 200 to 2 million pC with CMD2000) ensures guaranteed accuracy even in the partial load area. The CMD charge amplifier reliably records and evaluates small process values too.
Best price/performance ratio
The CMD operates reliably with both HBM transducers and data acquisition systems as well as third-party products. The standard 10 V analog signal output guarantees that the amplifier can be operated with virtually all measurement systems. Furthermore, the Ethernet interface enables measured values to be transmitted using the streaming method providing up to 1 kHz bandwidth. The CMD charge amplifier offers performance features that are significantly superior to third-party charge amplifiers - at the same price.
Integrated highpass filter
CMD has an integrated highpass filter that effectively eliminates the drift affecting piezoelectric sensors. No signal loss occurs with fast, dynamic processes, because only the static and quasi-static signal components are filtered. The advantage: The CMD is not overloaded, even with long measurement times.

What are the benefits of CMD? See the interview with Michael Guckes, Product and Application Manager at HBM Test and Measurement.
- Measuring range from 50 up to 2 million pC (freely scaleable)
- Measuring of signals at frequencies of up to 50 kHz
- Adjustment of the measurement range via SensorTeach
- TEDS functionality for automatic sensor identification
- Electrically isolated signal inputs and outputs
- IP60 degree of protection for CMD600/2000, IP65 degree of protection for CMD600-P
Quick and reliable sensor adjustment
The adjustment of sensors used in the force shunt is a prerequisite for accurate and reliable measurements. PACEline CMD now comes with an integrated adjustment assistant, which guides users through the necessary steps. The setup parameters are automatically documented.
Furthermore, the software included in the scope of supply allows ease of use and parameterization of the amplifier. It automatically identifies equipment connected to the network via TCP/IP, enables the IP address to be set (remote maintenance by Industrial Ethernet) and measured values to be recorded for monitoring and diagnostics.
The Industrial Ethernet interface permits direct transmission of all process monitoring parameters from the machine control to the CMD digital charge amplifier. If no computer or machine control with an Ethernet interface are available, the CMD can also be parameterized via the digital input. An LED status display enables diagnostics directly on the equipment.
Furthermore, the CMD charge amplifier software provides a line recorder. Measured values and measurement curves can conveniently be visualized online. This enables stored process values to be used for subsequent analysis of the machine so as to analyze the production process and further optimize it.
Integrated into the world of automation
CMD can be easily integrated into downstream automation systems using the measurement signal output's voltage output that is electrically isolated from the mains (+/-10 V). The signal can be used either for transmitting the actual measured value or peak values.
The Ethernet interface enables the CMD charge amplifier to be used in networks through to remote diagnostics. In addition, CMD is suitable for operation in controls used in production.
HBM provides software modules and programming examples needed for easy implementation in Simatic-Step7.
Integration into applications programmed under LabView is easily achieved - thanks to the CMD LabView driver and the examples available from the system CD included in the scope of supply and from the download area.
In addition to the industrial amplifiers HBM provides the appropriate ePLAN macros. They allow easy and error-free integration of the instruments in the project planning of the automation environment.
ePLAN Electric P8 is an engineering tool for modern CAE software supported by a database and facilitates consistent project planning, documentation and administration of automation systems. ePLAN macros enable users to easily integrate the process controllers in their project planning. Parts data, drawings and pin assignments are available in ePLAN Electric P8 immediately after import of the macros.
The free macros are available on the documentation CD included in the process controllers' scope of supply and can also be downloaded here.
