The axial displacement monitor is a kind of monitoring instrument which is specially used to measure the relative axial position change of rotor and static part of large-scale rotating power machinery. It can continuously measure and monitor the axial displacement of single (two) channels, receive signals from two approaching displacement sensors, and display the direction and size of rotor axial displacement on the display, and has standard analog output. The device can also send out warning and danger signals to indicate that the displacement exceeds the set alarm value or danger value. The instrument has power failure protection, digital password protection and watchdog circuit, which can ensure the instrument to recover automatically from "trap" and confusion. It is suitable for monitoring and protecting the axial position of steam turbine, water turbine, compressor, blower and other rotating machinery. The integrated shaft displacement transmitter is integrated with a preamplifier. The function of the transmitter only needs probe and extension cable. It has all the functions of the split type, and saves the front-end device, so that the monitoring components are further reduced and the reliability is greatly improved. The axial position of the rotor is monitored with respect to the main rotating bearing bush.
