Digital Pressure Sensor
E8F2
CSM_E8F2_DS_E_4_3
Pressure Sensor with
Easy-to-Read LED Display
• Pressure status can be checked at a glance from the
digital display and bar display.
• Measurement pressure prevents incorrect outputs due
to momentary pressure changes. (*)
• Perform automatic teaching simply by teaching pressure
values for good and bad products.
• Industry’s smallest models at just 28
