The TR890 Series Electronic
PID Controller is designed for
use on applications where
large load changes are
expected, or extreme accuracy
and fast response times are
needed. With full auto-tune
capabilities and a large
selection of available inputs,
the TR890 Series is ideally
suited for use with a Watson
McDaniel Control Valve.
Use of a Watson McDaniel
No. TA987 Air Filter/Regulator
is recommended for filtering
and regulating the pressure of
plant compressed air, and for
delivering clean, dry air at
the proper pressure to
pneumatic control devices.
