Problems with the Bentley 3300 shaft displacement and shaft vibration sensor probes
Thread Content
For the Bentley 3300 shaft vibration sensor, what changes occur in the voltage and current values as the sensor probe gets closer to the metal? (Do the voltage and current values increase or decrease simultaneously?) For the Bentley 3300 shaft displacement sensor, what changes occur in the voltage and current values as the sensor probe gets closer to the metal? (Do the voltage value and current value increase simultaneously or decrease simultaneously?)
As the Bentley displacement probe gets closer to the metal, the voltage value decreases, and the displacement is displayed as a positive value
The closer to the metal, the higher the voltage! Note that the voltage is negative! It shows a negative value of over -20 volts when not near metal
The relationship between voltage value and distance is 200 mV per mil; 1 mil equals 1/1000 inch. In other words, the greater the distance, the higher the voltage value, though this is only true within a certain range of distances. It’s similar to the case with displacement and vibration probes.
