If you need to measure the DCS channel, you can use a 4-20MA signal
Is the oil level given as 4-20mA and is vibration also involved?
The fan reducer is equipped with an integrated detection probe that monitors oil level, oil temperature, and vibration; it outputs a 4-20mA signal which can be directly connected to the DCS
3 instruments naturally mean 3 ranges.
Not all circulating water probes are multi-functional; how could Bentley be used in such cases?
By applying an analog signal to the card, only the DCS range can be verified.
Several probes are installed on the fan – so-called x and y axis vibration probes, as well as probes for monitoring oil temperature and oil level. These probes are used to monitor the operation of the fan, to determine whether there are any abnormalities, and to protect the fan; they don’t have any other special functions.
