Systems and methods for data collection and frequency evaluation for pumps and fans

A method for collecting data in an environment comprising pumps, the method comprising:

• collecting data from a plurality of input channels, wherein a subset of the plurality of input channels is communicatively coupled to sensors measuring operational parameters of a pump;
• storing one or more frequencies related to an operation of the pump;
• interpreting a plurality of detection values from the collected data, each of the plurality of detection values corresponding to at least one of the plurality of input channels;
• and
• detecting a signal on one of the plurality of input channels at a frequency higher than the one or more frequencies at which the pump operates.

A monitoring system for data collection in an environment comprising fans, the system comprising:

• a data collector communicatively coupled to a plurality of input channels, wherein a subset of the plurality of input channels is communicatively coupled to sensors measuring operational parameters of a fan;
• a data storage structured to store one or more frequencies related to an operation of the fan;
• a data acquisition circuit structured to interpret a plurality of detection values from the collected data, each of the plurality of detection values corresponding to at least one of the plurality of input channels;
• and
• a frequency evaluation circuit structured to detect a signal on one of the plurality of input channels at a frequency higher than the one or more frequencies at which the fan operates.
