Key features
Accurate conversion: it can convert the charge signal into linear and stable voltage signal, which can simplify the back-end processing of the signal.
Low noise: the built-in high-performance amplifier circuit can ensures signal integrity,twist-resistant transmission and signal loss even on long distance and high impedance load.
Wide frequency response: it can be used in the frequency range of 0.5 Hz to 10 kHz, suitable for the frequency of a variety of mechanical equipment vibration.Full protection functions, well input over-voltage protection, good electromagnetic compatibility, enhancing the reliability of the system operation.
Typical cooperation cases
North American refinery: In the centrifugal compressor group of a large refinery, EA402 is used as the core monitoring unit. It is connected to the DCS system through a 4-20mA signal to realize real-time alarm of vibration exceeding the limit. In the past three years, it has successfully warned of two rotor imbalance faults to avoid unplanned shutdowns;
European offshore wind farm: EA402 913-402-000-012 is used in the offshore wind turbine variable pitch system. Its IP65 protection level effectively resists the high humidity and salt spray environment. With the solar power supply module, it has been running stably for more than 5 years, ensuring that the vibration state of the variable pitch mechanism is controllable;
Middle East petrochemical enterprise: In the steam turbine monitoring project, EA402 is linked with the infrared temperature measurement module to build a "vibration + temperature" multi-parameter monitoring system for the equipment, which increases the accuracy of equipment fault diagnosis to 92% and greatly reduces maintenance costs.
