Chell has used
its considerable experience in the supply and calibration of pressure
and flow transducers to develop what we consider to be the most versatile
controller / display / power supply
on the market.
The CMD100 can be used as a process controller as it incorporates a fully
adjustable and self-learning PID algorithm. The CMD100 can be configured
to
control any of the 4 analogue inputs using the PID
control. The process can be controlled by driving a
standard 100 Ohm process valve (as commonly
fitted to flow controllers) or it can control via the flow
controller setpoint.
The PID control parameters can be set using the
CMD100’s autotune facility or the P, I and D values
can be edited manually.
It can also be used as a self-contained power
supply and display for gas mass flowmeters and
controllers, pressure transducers or any other
device with a voltage or current output. The
transducer signal can be scaled displayed and then
used to control another device or retransmitted in
many different ways .These include voltage or current
analogue signals.
Configuration extends to displayed units and real
channel names, not just channel numbers.
