Industrial Charge Amplifier.
The model 421A25 is the latest electronic unit to be
introduced. It has been designed primarily for use
with a charge mode force sensor to enable dynamic
force monitoring in the industrial environment.
This unit will connect to any piezoelectric sensor having a pC
charge mode output, and serves to amplify the signal to provide
level and peak monitoring of dynamic behaviour.
When used with an appropriate sensor, this amplifier is ideally
suited to applications such as press monitoring, as well as
crimping or stamping operations.
The amplifier is built into a rugged die cast aluminium housing,
and can be pre-programmed via the built in RS-232 interface,
and has a self check function. The sensor is simply connected
to the BNC input connector on the side of the housing, with the
computer using the other connector for setting up.
The model 421A25 has continuous gain settings and 16 different
input ranges from 100pC to 1,000,000pC, and also allows for
force level monitoring via two built in adjustable alarm outputs.
There is a peak hold and reset function, so that repetitive operations
can be monitored.
