Single Conditioning


Measured Units:

  • RPM
  • Acceleration in RPM/Minute
  • Direction of rotation


Measured Parameters:

  • Direction (Forward / Reverse)
  • Speed
  • Acceleration
  • Peak Speed
  • Gap / Bias voltage


Peak Speed:

Retains the value of the highest speed observed, per channel, since the module was powered up or since the "peak speed" value was manually reset.


Measurement Modes:

  • Dual Channel—Inputs are used independently to perform two separate speed, acceleration and peak speed measurements.
  • Single Redundant Channel—One sensor is used to perform the speed, acceleration and peak speed measurement. If the current sensor fails the module automatically switches to the second (redundant) sensor.
  • Reverse Rotation—Two sensors are used to monitor both the speed and direction. The first sensor measures the speed, acceleration and peak speed in the forward direction. The second sensor measures the speed, acceleration and peak speed in the reverse direction.


Amplitude Range:

Dependent on sensitivity


Integration:

One level provided in hardware


Low Pass Filters:

Independently configured per channel

  • Optional Overall measurement LP filter: 200 Hz - 20 kHz; Roll Off: -24 dB per octave


High Pass Filters:

Independently configured per channel

  • Integration OFF: 1, 5, 10, 40, 1000 Hz, Roll Off: -30 dB per octave for the 1 Hz HPF, otherwise -24 dB per octave
  • Integration ON: 5, 10, 40, 1000 Hz, Roll Off: -30 dB per octave for the 5 Hz HPF, otherwise -24 dB per octave
