KSA-15 Axial Shift Unit
The axial shift unit is used for measuring the axial shift of the controlled object’s rotor, displaying its value on the dial test indicator, emergency or warning alarm in case the gap thresholds are exceeded, channel failure alarm, when the power voltage goes beyond the setpoints.
The axial shift unit is a part of the KSA-15 control and alarm system for measuring the vibration of rotor machines and mechanisms in industrial conditions in various industries.
Elements
· Normalizer
· Amplifier
· Control unit
· Voltage stabilizer.
Functions
· Displaying the axial shift values on the dial test indicator
· Providing the output voltage proportional to the value of the axial shift, with the sensitivity of 5 V/mm
· Providing the output voltage proportional to the value of the axial shift, with the sensitivity of 5 V on the final value of the working part of the scale in millimeters
· Alarm signaling in case the measured axial shift values are beyond the threshold
· Channel failure alarm signaling in case the gauge voltage is beyond the setpoints
· Alarm signaling is provided by indicating lights and switching relay outputs
· Operating mode - continuous, round-the-clock.
