The Measuring Chain - HBM CMD Serie Bedienungsanleitung

Device description
26
The output signals can be transferred to an industrial
controller for monitoring, control and optimization of a
production process.
The device is controlled via digital inputs and the Ether­
net interface.
With its robust aluminum housing, wide power supply
range of 18 to 30 V, and degree of protection IP60
(CMD600P: IP65), the amplifier is designed for use in an
industrial environment and for mounting really close to
sensors. However, the degree of protection only applies
if the connection sockets either have connection cables
attached, or are covered by protective caps.
The charge amplifier is parameterized with the CMD
Assistant PC software. Measurement data can be visuali­
zed and also saved. Device settings can be saved to PC
for backup purposes and also loaded into the charge am­
plifier later.

The measuring chain

Accurate measured values can only be obtained with reli­
able measurement technology. A typical measuring chain
consists of a piezoelectric sensor with cable and a
charge amplifier.
The analog voltage signal of the CMD can be analyzed
and evaluated in evaluation systems (data acquisition
and evaluation, cycle control). This is usually imple­
mented with a PLC.
In order to achieve correct results, the measuring chain
must be individually configured and adjusted.
