1: Description
1-1: General
The field mount type indicating controllers measure and indicate various types of
process variable (PV) and, at the same time, they compare the process variable with
the set point (SP) and generate a pneumatic control output signal of 20 to 100 kPa
{0.2 to 1.0 kgf/cm²}.
Setting of the set point value can be done either in the local mode with the manual
setting knob (this knob is adjustable either inside the casing or from outside of the
casing) or in the remote mode with an external pneumatic signal. These instruments
also can transmit a pneumatic signal of 20 to 100 kPa {0.2 to 1.0 kgf/cm²} which is
corresponding to the measured process value.
The only difference between pressure measuring instruments and temperature
measuring instruments is their sensor element.
1-2: Structure
The KF instrument is comprised of three major units, namely, casing, circuit board on
which various units are mounted, and pressure sensor (or temperature sensor).
