1-1 Main Features of the K3MA
The K3MA is a digital panel meter that is capable of converting an input signal into a
digital value and displaying it on the main indicator.
The main features of the product include the following.
Measurement This feature measures an input signal and displays it as a digital value.
The input signal to be measured by each type is as follows.
Scaling This feature converts an input signal into a
desired physical value.
(Only K3MA-J/F) For example, when a pressure sensor is
connected, in which a current range of 4-20
mA corresponds to a pressure range of 0-100
kPa, the readout for the input of 4 mA is
converted into "0" and that for the input of 20
mA is converted into "100" (kPa). Since
Scaling converts an input signal as a value of
current into a unit (kPa) that is used in the
system, it will enable you to get the value
intuitively.
