The E8F2 provides output according to the measured values to control external devices, such as valves and pumps. In order to control
the external devices, a reference value can be set so that the output will be ON or OFF if the measured values are above or below the
reference value. The output ON- and OFF-point settings are described below, provided that the output is normally open.

Bar Indicator
The user can visually sense the measured pressure according to the ON and OFF points from the bar indicator. This indicator is available to OUT1 output only. There is a difference in indication mode between hysteresis mode and window mode.
• Hysteresis Mode
The five LEDs indicate the present pressure provided that the ON point is between the second and third LEDs from the left.

(ON point)
The indication range per LED is obtained from the following.
• 300 kPa ≤ 1 MPa x 1/2
• 300 kPa x 1/3 = 100 kPa
The first through third LEDs from the left are all ON under condition 1. The indication range per LED is the set value of the indication
range in special setting mode. If the set value is aut, the following ranges are obtainable.
When ON point ≤ Rated pressure x 1/2
Indication range per LED = ON point x 1/3
When ON point > Rated pressure x 1/2
Indication range per LED = (Rated value -- ON point) x 1/3
Window Mode
The distance between ON and OFF points are divided into five equal portions. The present pressure will be indicated by a single
LED that will be ON. The left LED will flash if the present pressure is below the ON point and the right LED will flash if the present
pressure is above the OFF point.

Precautions
J ENVIRONMENT
•
•
•
J MOUNTING
Do not use the Sensor in locations subject to explosive or
flammable gases.
Do not use the Sensor in an environment subject to corrosive
or combustible gases.
Make sure that the Sensor is free of water.
J AVOID DAMAGE TO THE E8F2
•
•
•
•
•
•
•
Do not impose any voltage exceeding the rated voltage on
the E8F2.
Do not short-circuit the load connected to the E8F2.
When supplying power to the E8F2, make sure that the polarity of the power is correct.
•
•
J WIRING
•
•
Do not wire power lines or high-tension lines adjacent to the
lines of the E8F2.
If no linear output is used, cut the gray lead wire short and
apply insulating tape to the lead wire so that it will not come
into contact with any other terminal.
•
Mount the Sensor so that ultrasonic vibrations will not be
applied directly to the Sensor.
Do not insert any wire into the pressure port. Doing so may
damage the pressure elements and cause a malfunction.
Do not apply a tensile strength in excess of 50 N (11.25 lbs)
to the cords or connectors.
The pressure-introducing section (aluminum die-cast made)
is fixed with tapered 1/8 NPT male screws and M5 female
screws. When using tapered screws, use tapered 1/8 NPT
female screws.
Wrap the tapered 1/8 NPT male screws with sealing tape to
prevent any leakage. Tighten the male screws to a torque of
10 NSm (7.38 ftSlbs) max.
Tighten M5 female screws to a torque of 2 NSm
(1.48 ftSlbs) max.
Tightening each male screw by using a 12-mm wrench to
hold its hexagonal head, not the screw itself.
E8F2
Hexagonal head
•
When attaching the Mounting Bracket to the Sensor, make
sure that each M3 screw is tightened to a torque of
0.5 NSm (0.37 ftSlbs) max.
NOTE: DIMENSIONS SHOWN ARE IN MILLIMETERS. To convert millimeters to inches divide by 25.4.
