3. Sensor Head Installation
1) Cut the cable to an appropriate
length and strip away about 25
mm of the outermost insulation.
Note: It is not necessary to
remove insulation from the
core wires.
2) Insert the cables after aligning
them with the colors on the seal
on top of the connector body.
3) Press together the body and the
connector cover into which the
cables were inserted to make a
connection (use a pair of pliers
or similar tool to press them together).
4) Insert the sensor head connector into the hole of the amp unit.
To remove the connector, depress the connector lock and
pull it out.
* Do not reuse sensor head
connectors that have already
been pressure-connected.

*Hysteresis when operating in general-purpose mode and application
modes 1 and 2 is 0.5% of F.S. in the standard and high-speed modes.
During focus mode operation, it is 0.1% of F.S.
■ Variable hysteresis mode (F-2)
Two detection points may be user-configured, and hysteresis for both
may also be set.

■ Window mode (F-3)
The user may select a pair of upper (Hi) and lower (Lo) thresholds, and
the sensor turns OFF when the pressure falls outside of the resulting
range.
*Control output 1 is 0.5% of F.S. during standard and high-speed
operation, it has a hysteresis of 0.1% of F.S. in the focus mode, and

Connections
●
Always ground the frame ground terminal when using an off-the-shelf
switching regulator.
●
Use separate conduits for power line and high voltage lines , since use
of a common conduit may result in device malfunction caused by noise .
●
Improper wiring may result in the device becoming excessively hot or
in device damage.
Notice about CE marking
●
Attach the ferrite core (OP-87505) if you extend a sensor head cable/
amplifier power cable to 3 m or more to use.
(Attachment position: within 100 mm from the amplifier unit of a
power cable, Number of turns: 2)
Other
●
Do not use this sensor with corrosive gasses or liquids.
●
Do not insert objects such as wire into the pressure insertion area.
Doing so may result in the device failing to operate properly due to
damage to the pressure-sensitive elements.
●
Do not use sharp-tipped objects to press the setting keys.

.Explanation of Features
■ Focus mode
Focus mode increases all display resolutions by a factor of 10.
Normal mode Focus mode
The following focus center pressures can be selected for the models
noted in the table below. (Unit: kPa)
* The current value is displayed as ±20% of the F.S. range with the
focus center pressure as the reference value (0).
■ Zero shift
Zero shift input forces the pressure at that time to be defined as zero.
This feature is useful in applications that require the detection of a certain amount of pressure fluctuation without being influenced by changes
in the original pressure.
(Example: leak testing)
Zero shift input received when a container is filled with air will allow the
amount of leak after a certain time to be displayed as negative pressure.
This approach eliminates the influence of small variations in the final fill
pressure of the container.
The pressure value (reference value) when zero shift input is received
can be verified from the current value display by pressing the button
to switch to the reference value display.
( ⇔ )
Press the button once more to return to the current value display.
■ Analog output
A voltage corresponding to the pressure value is output.
* Ambient pressure compensation is also applied to analog output.
■ Power-save
The value display will be turned off during power-save operation to reduce the amount of power consumed.
●
Use of any keys during eco mode operation will revert the sensor to
its normal display. The sensor will return to the eco display when
there is no key input for a period of 3 minutes.
■ Switching the display color
Corresponds to either output 1 or output 2 based on which setting display has been selected.
* rGr can only be set when either the F-1 or F-2 mode is selected.
Values that fall between the P1 and P2 settings will be displayed in
green, while values outside that range will be displayed in red.
11
.Active Tuning
■ Perform these steps first
Select the setting display as indicated below before performing the
tuning procedures.
Active 2 point tuning: Select either P1 or T1 for the setting display.
Active 1 point tuning: Select P2 from the settings display.
■ Active 2 point tuning / a tuning method suited for automatically configuring suction pick-up detection pressures
The zero shift timer setting is manually configured, and the sensor automatically selects the best pressure setting (P1) for this value.
* When focus mode is being used, the analog output will not be focused.
■ Peak/bottom hold display
The maximum (minimum) values are displayed continuously after power to
the sensor is turned on.
The active hold display indicated below is used when the A-1 mode is selected.
How to display hold values/
From current value/reference value display
+ / Activates peak hold display.
+ /Activates bottom hold display.
The minimum value during zero shift input is displayed for the bottom
hold during A-2 mode operation.
Resetting the peak/bottom hold values/
Pressing for 3 seconds or more while the peak and bottom hold
values are being displayed will reset the values.
*The values will also be reset when power to the sensor is turned off,
and when the device's detection mode or operating mode is changed.
●
During A-1 mode operation (active hold display)
The hold values are reset each time the pressure value exceeds (or falls
below) the setting, and the peak hold (bottom hold) will then vary from
this point.
Peak hold value:
Bottom hold value:
The peak hold value will be reset once a value is
encountered that exceeds setting P1, and new peak
values will be held from that point.
The bottom hold value will be reset once a value is
encountered that falls below setting P2, and new
bottom values will be held from that point.
■ Active 1 point tuning / tuning optimized for vacuum burst
detection
The sensor automatically selects the best pressure setting (P2) for
vacuum burst detection.
12
.Ambient Pressure Compensation
Open the applied pressure to the surrounding air so that it equals the
ambient pressure and press the button for 3 seconds or more while
the current value or reference value is being displayed.
The ambient pressure point will be corrected.
*1 Ambient pressure can be corrected within a range of ±5 % of F.S.
When atmospheric pressure compensation has been performed, the
settings will be saved even when power to the sensor is turned off.
*2 Can also be used when operating in focus mode, although for some
center pressures the display will read FFF.
(Atmospheric pressure compensation is being performed.)
13
.Key Lock
Disables operations that would modify the sensor’s configuration. Display
content can be toggled.
Pressing and holding either or for at least 3 seconds while pressing
button will lock the keypad and cause the display to flash.
* The same key combination will deactivate the key lock feature.
