Pressure Sensor
Four-channel Pressure Sensor
Offers Versatile Functions and High
Precision without Errors
H
The industry's smallest pressure sensor,
compact, lightweight – ideal for robot
arms or other moving components
H
A highly sensitive minute-pressure
sensor model detects very small
differences in air pressure
H
Requires no wiring conduit – can be
located for sensing in small places
H
Simple display panel efficiently saves
space, but offers large LEDs
H
Easy sensitivity adjustment using the
teach function and channel-to-channel
copy function
