Digital Pressure Sensor
E8F2
CSM_E8F2_DS_E_3_1
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.
Industrys smallest models at just 28 28 29 mm.
