Digital Pressure Sensor
E8F2
Pressure Sensor with
Easy-to-Read LED Display
Pressure status can be checked at a glance
from the red digital pressure value and analog
bar displays.
Measurement pressure is averaged by the
chattering prevention function to prevent
incorrect outputs due to momentary pressure
changes.
The automatic teaching function teaches
pressure values for good and bad products.
Industry’s smallest models at just 28 × 28 ×
29 mm.
Be sure to read Safety Precautions
on page 6.
