Axis displacement vibration probe ECS-3180-51-00 Axis vibration transmitter probe ECS-303-00-16-05-01-00 Displacement probe ECS-303-00-08-05-01-00 Axis vibration function module, equipped with two displacement sensors produced by our company, can simultaneously monitor the shaft vibration of two channels, mainly used to measure the vibration of the rotor relative to the bearing cover of large rotating mechanical devices (such as turbines, fans, compressors, motors, etc.); When the vibration level exceeds a certain set limit, the functional module emits a light alarm signal and a relay contact control signal; The axis vibration function module has a high degree of intelligence. The module adopts advanced embedded microprocessors and is equipped with large-scale digital and analog integrated circuits. It can be easily connected to the upper computer, DCS, and handheld computer through RS232, RS485, and handheld computer I/O interfaces, respectively The upper computer and handheld computer can conveniently configure the functions and manage data of the module The main function is to display the vibration values of two channels simultaneously Set alarm values, alarm delay values, alarm reset methods, clear historical peaks and valleys, and use or disable any one or two channels through configuration software or handheld computers Each channel is divided into two alarm contacts: upper limit alarm and upper limit alarm, which are respectively indicated by LED light-emitting tubes Automatically remember and save the maximum (peak), minimum (valley), and historical alarm states detected during a certain period of time for users to view or process; The set parameters and historical data can be saved for a long time after power failure Equipped with power on and power off protection functions (protecting historical data and suppressing false alarms); Self locking alarm output function within 25 seconds after power on; LED failure indication and alarm output when input signal is abnormal; It has a disconnection detection function, which can cut off the alarm output circuit when disconnected, effectively suppressing instrument false alarms ■ 4-20mA or 0-10mA current output corresponding to the range, convenient for connecting to DCS. ■ It can be connected to the upper computer or DCS communication through RS232 or RS485 communication interface by RS22-RS485 converter; The regulator adopts a fully isolated input and output design, which can truly provide on-site anti-interference capability. The input end uses a precision instrument amplifier, which effectively suppresses common mode interference caused by long-distance transmission on site, ensuring that the signal entering the signal conditioner is the true vibration signal of the machinery itself.

Mainly applicable to fields such as water conservancy, electricity, steel, metallurgy, chemical industry, petroleum, and mineral resources, it continuously monitors and measures the vibration of various rotating machinery in real-time. Facilitate users to understand the real-time operation status of the device, and conduct analysis and maintenance. When the vibration of the equipment exceeds the normal value, the vibration monitor will immediately issue an alarm and danger signal, so that your equipment can be protected in a timely manner. It is mainly used for monitoring and protecting large machinery and rotating equipment that operate continuously. It can avoid equipment damage caused by abnormal operation and increased vibration amplitude. It is a monitoring instrument for equipment maintenance and upkeep. During user use, the control value (mm/s) for vibration intensity (speed) can be set based on the allowable vibration level of the device. When abnormal phenomena occur during the operation of the equipment, the vibration speed increases, and the vibration speed value is greater than the set value, the yellow warning indicator light will turn on. If the continuous overshoot time exceeds the set delay time, the red indicator light will turn on and the internal relay of the instrument will activate. Effectively cutting off the main power supply of the control equipment, forcing the equipment to shut down, preventing accidents, and achieving the purpose of protecting the equipment. Users can directly adjust the warning and alarm values on site according to their needs, with simple operation and easy on-site measurement. The instrument can be connected to two magnetic electric speed sensors simultaneously to continuously monitor the vibration of the casing or bearings of rotating machinery such as motors, blowers, compressors, etc. in the vertical or horizontal direction. The vibration monitoring and analysis system for rotating machinery is a high-tech product that integrates sensor technology, signal processing, computer applications, expert systems, and other technologies. The system continuously monitors the vibration parameters of rotating machinery online, timely understands the operating status of the unit, provides important data for the pre diagnosis of accident symptoms, and provides reliable guarantee for the safe operation of the unit. In addition, the system also provides a technical foundation for enterprises to establish a scientific predictive maintenance mechanism: that is, through the rigorous monitoring and analysis of the system, to determine whether there are abnormal or faulty trends in rotating machinery.
