Three parameter combination probe

Three parameter combination probe:Mainly used for real-time monitoring of the vibration speed, lubricating oil temperature, and lubricating oil level of the cooling tower fan during operation. When the vibration speed or lubricating oil temperature exceeds the given value, an audible and visual alarm is triggered, and the power supply of the fan is automatically cut off through relay contacts to protect the fan; When the lubricating oil level is below the lower limit or above the upper limit, a corresponding flashing alarm will be triggered to remind the user to take measures.

Advanced technology and scientific research achievements were widely adopted in the design process, which has the following significant characteristics:

The collection of three parameters, namely vibration speed, oil temperature, and oil level, is completed by a combination probe, and the monitoring and processing are completed by a secondary instrument. Therefore, the installation is convenient, and the main control cabinet can leave more space for installing other instruments;

Secondary instruments use microprocessors for data acquisition, processing, and output, resulting in higher reliability, stability, integration, and intelligence levels;

3. It has a standard 4-20mA current output interface and can be connected to a computer controlled by a cluster;

The vibration sensor adopts advanced integrated circuit chips, with high accuracy, stable and reliable operation;

The combination probe is installed on the observation window cover, which is the maximum point of fan vibration;

The connection between the primary and secondary instruments adopts a current interface, which can achieve a longer transmission distance, stronger anti-interference ability, and higher data reliability.

The 7 primary instruments adopt strict sealing technology and a secure installation method, which greatly improves the working life of the primary instruments under harsh conditions.

Due to the use of hardware and software measures, most of the instantaneous large vibration values caused by unexpected factors (such as gusts) can be removed from the data array, greatly reducing the false alarm rate.
