PACEline CMD Digital Charge Amplifier: Measures Signals From 50 pC to 2 Million pC

The PACEline CMD digital charge amplifier for piezoelectric sensors precisely measures fast force, torque and pressure signals. It is ideally suited to highly dynamic applications such as production monitoring in press processes or end-of-line testing in the automotive sector due to its very wide measurement range and fast data acquisition up to 50 kHz. PACEline CMD can be easily integrated via digital or analog interface and parameterized via Ethernet as well as Software and Adjustment Assistant. 

  • HBM accuracy class: 0.5
  • Measurement ranges: between 50 pC and 2 million pC
  • Degrees of protection: up to IP 65

Wide measuring range

  • Very wide measurement range and high dynamics
  • Measurement range freely adjustable or via SensorTeach
  • Calibration certificate included in scope of supply
  • Guaranteed accuracy also in partial ranges

Can be used in many applications due to extremely wide, individually adjustable measurement range.

Easy to use

  • Direct data transfer via Ethernet interface or 10 V analog output
  • Digital and analog signal inputs and outputs, peak value detection
  • Integrated Assistant for time-saving sensor adjustment
  • 2 parameterizations enable formulations to be quickly changed
  • Parameterization software including chart recorder and data storage

Easy to program and use due to digital interfaces and software support.

Highly reliable

  • High signal quality with 14 bit resolution
  • Robust design featuring IP 60 and IP 65 degree of protection
  • Selectable high-pass filter minimize signal drift
  • Electrically isolated signal inputs and outputs prevent faultsFast data acquisition up to 50 kHz measurement frequency

High-quality measurement result due to robust design and high EMC interference protection

CMD LabView driver and example project

To simplify the use of CMD meauring amplifier a complete support for communication in form of a Labview driver is available, respectively Labview programs/subroutines called virtual instruments (VIs).
The purpose of this document is to explain in detail all aspects of the Labview CMD driver:

  • Driver structure
  • VI blocks
  • Application example – getting started

The CMD driver is completely written in Labview Professional Development System. In order to use the drivers the user will need Labview version 9.0.1 or later.
This example does not imply any warranty or guarantee.

CMD Siemens Profinet integation example project

This is an instruction for using a CMD charge amplifier with a Siemens 1200 controller in a Profinet network.

It shows how to stream data via UDP from the charge amplifier to the controller via UDP with up to 1000 Hz and send a command via TCP.

This non-real-time communication can be performed simultaneously to an existing real-time ProfiNet connection over the same line.

Communication is done with program blocks, which are enclosed with the technote in the .scl file.


HBM does not guarantee the completeness and correctness of this example.
