Sensors NCS

NCS 1002

MEMS Accelerometer (±18g, DC…2500Гц, 15кГц/g).

The sensor detects on the support bearing unit of the vertical, transverse or axial component of vibration and generates a corresponding electrical signal proportional to the acceleration, to the control module.

Recommended for turbines, pumps, compressors and other equipment.

ncs 1002

Can be operated in an atmosphere containing water vapor, oil, dust, can be operated in submerged state.

The method of installation of the sensor (through-bolt) eliminates twisting and kinking of cable during installation.

Frequency-modulated output signal enables the signal transmission to a distance of over 1000 m without additional intermediate converters and amplifiers.
