S141C, Proximity sensor

Description

Proximity sensor in a rectangular housing for non-contact measurement of displacement (differental rotor expansion) in range 0…30 mm, with an electronic unit built into the sensor housing.

Used in vibration monitoring channels of supports together with the controllers of the "Vibrobit 300" and "Vibrobit 500" systems.

Key features:

rectangular housing
standard temperature range
3-wire connection scheme
capability to operate with "narrow collars" (down to 20 mm).
