Equipped with independent two output and three output modes
Equipped with auto-reference / remote zero-adjustment functions,
More precise pressure management is possible with a minimum of effort
Equipped with two independent comparative outputs, and separate sensing modes can be selected for each of them.
Two comparative outputs are provided, so that one of the outputs can be used as a warning output. In addition, if an
output is not being used, it can be disabled.

The display is forced to “0”, and only the
filling pressure drop range is displayed.
0
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

With auto-reference function applied
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
If the reference pressure of the device changes, the auto-
reference function partially shift the comparative output
judgment level by the amount that the reference pressure
shifts, and the remote zero-adjustment function can
resetthedisplayvaluetozeroviaexternalinput.These
functions are ideal for places where the reference pressure
