Switching is possible between analog voltage output and external input
Multi-function type is available that allows selection of analog voltage output or external input (auto-reference / remote zero-adjustment).
This is suitable for multi-specification applications.
Equipped with auto-reference / remote zero-adjustment functions
More precise pressure management is possible with a minimum of effort
If the reference pressure of the
device
reference function partially shift
the
judgment level by the amount
that the reference pressure
shifts, and the remote zero-
adjustment function can reset
the display value to zero via
external input. These functions
are ideal for places where the
reference pressure fluctuates
wildly, or where fine settings are
desired.
When auto-reference input is applied, the reference pressure ‘30’ is added
to the threshold level. If the reference pressure changes to ‘20’ or ‘40’, the
auto-reference input compensates for this every time by changing the
threshold level, so any variation in the filling pressure can be ignored.

Pressure
When remote zero-adjustment input is applied, the reference pressure is forced to ‘0’.
If the reference pressure changes to ‘20’ or ‘40’, the remote zero-adjustment input
adjusts the reference pressure to ‘0’ every time the reference pressure changes, so
any variation in the filling pressure can be ignored.
Because the threshold level is fixed for conventional pressure sensors,
changes in the reference pressure result in wrong decisions.
