Product catalog summary

Applications

Turbine/Generator Sets
Fans or Blowers
Motors
Gear Boxes
Bearing Caps

Features

4-20 mA output proportional to target's axial position
Compatible with major probe types
DIN Rail mountable
Probe failure detect modes
BNC buffered output and Gap voltage

The 1-830 series axial displacement transmitters are part of CEC's line of vibration transmitters. These devices are single-channel signal conditioners that interface with proximity transducers like the 3300, 3300XL, and 7200 series. They provide a calibrated 4-20 mA output proportional to the axial position sensed by the transducer. The probe gap and buffered dynamic signal can be accessed via the front panel BNC. Probe failure conditions are indicated by a multicolored status LED and the 4-20 mA output, providing instant feedback during installation or operation.

1-830 Axial Displacement Transmitter Applications • Turbine / Generator Sets • Fans or Blowers • Motors • Gear Boxes • Bearing Caps • 4-20 mA output proportional to targets axial position • Compatible with major probe types • DIN Rail mountable • Probe failure detect modes • BNC buffered output and Gap voltage The 1-830 series axial displacement transmitters continue the successful line of vibration transmitters designed and manufactured by CEC. These single channel signal conditioners interface with proximity transducers like the 3300, 3300XL and 7200 series or probe types with similar specifications. Probe failure conditions are quickly identified via the multicolored status LED and the 4-20 mA output. This unique feature allows for instant feedback of the probe system condition during installation or machine operation. Each unit provides a calibrated 4-20 mA output that is proportional to the targets axial position as sensed by the transducer and extension system. The probe Gap and buffered dynamic signal are easily accessed via the front panel BNC.
