N1xxC, rotation speed sensor

Description

Eddy current sensor in a cylindrical housing for non-contact measurement of rotor rotational frequency (range 0…6000 Hz), with an electronic unit integrated into the probe housing. Output type: 4…20 mA pulse signal, three-wire connection. Maximum operating temperature up to +125 °C.

Designed for use in rotor rotational frequency monitoring channels together with the controllers of the "Vibrobit 300" and "Vibrobit 500" systems.

Key features:

sensor output signal — current pulses
compatibility with non-ferromagnetic materials
