Can be mounted on a DIN rail
Change-over to analog bar display possible
The sensor can be mounted even on a 35 mm
1.378 in
width DIN rail by using the
optional DIN rail mounting bracket (MS-DP-2).
It can be mounted in a narrow space inside of your device.
The pressure changes can be
indicated as a bar display. The analog
bar color reflects the changes in the
output. (The detected pressure value
is displayed in steps of 14 % F.S.
approx.)
Flexible control with four output modes
100 kPa compound pressure type available
To serve a broad range of pressure
needs, we offer
100.0 kPa, compound
pressure type, in addition to the 0 to
101.3 kPa and 0 to 1.000 MPa types.
Incorporated with the memory bank function
You can store two patterns of set
values. Hence, the setup can be
changed by a single touch.
Selection from six pressure units
The pressure unit can be selected from six
different systems to suit your requirement.
The selectable pressure units differ
with the sensor type. When the
pressure unit is changed, the
measured pressure value and the set
values are automatically converted.
MS-DP-2
High speed response of 2 ms or less
The sensor has a high speed response of 2 ms
or less.
In addition, the sensor has a chattering
prevention function. This allows change-over
of the response time so that fluctuation of the
reference pressure generated during operation
of the large-diameter cylinder and the ejector is
not detected as an abnormal pressure.

Hysteresis mode
The hysteresis of the output can
be set, as desired, with the set
values.
Window comparator mode
The output can be turned ON or
OFF by a pressure within the set
range.
Automatic sensitivity setting mode
Using actual objects, if the pressure
values for OK objects and NG
objects are input, then the sensor
automatically set to the optimum
pressure value (mid-value).
Forced output mode
The output is forcibly maintained
in the OFF state in the sensing
mode, irrespective of the set
values.
